Product Overview
Our Electronic Potting for Zener Diodes is a professional Silicone Potting Compound developed for the encapsulation, sealing, insulation and protection of Zener diodes. As a leading manufacturer of electronic Potting Compound and silicone raw materials, we optimize the formula for the voltage stabilization precision, high insulation, thermal stability and surge resistance requirements of Zener diodes. Unlike ordinary potting silicones, it features low dielectric loss, does not interfere with voltage stabilization performance, absorbs internal stress from temperature cycles, resists corrosion and ozone, and has excellent adhesion to aluminum, copper, stainless steel and PC/PMMA/PCB, effectively protecting Zener diode chips and ensuring long-term stable voltage stabilization for procurement partners.
Key Features & Advantages
- Low Dielectric Loss & Voltage Stabilization Compatibility: Low dielectric loss and excellent insulation, ensuring no interference to the voltage stabilization precision and reverse breakdown performance of Zener diodes, maintaining stable output voltage and electrical performance, which is critical for Zener diode performance in voltage regulation applications.
- Superior Insulation & Surge Resistance: Ultra-strong insulation performance (dielectric strength ≥25 kV/mm, volume resistivity ≥1.0×10¹⁶ Ω·cm), preventing short circuits and ensuring safe operation; effectively resisting voltage surges and electromagnetic interference, avoiding voltage drift and ensuring stable voltage stabilization of Zener diodes.
- Excellent Thermal Stability & Temperature Adaptability: Operating stably from -60℃ to 220℃, with outstanding high and low temperature resistance; excellent thermal stability ensures no obvious voltage drift of Zener diodes under temperature changes, absorbs internal stress caused by temperature cycles, protecting Zener diode chips and welding wires from damage.
- Strong Adhesion & Easy Operation: Excellent adhesion to aluminum, copper, stainless steel and other metals, as well as PC, PMMA and PCB materials (common in Zener diode modules), forming a tight seal without detachment; two-component design, easy to mix evenly, optional vacuum defoaming (0.01MPa for 3 minutes), supports room temperature or heated curing, full curing in 24 hours, suitable for batch production of Zener diodes.
- Environmental Protection & High Stability: Addition-curing silicone, non-toxic and non-hazardous, fully compliant with EU RoHS directive; low volatility, high strength, no stratification after long-term storage (stir before use without affecting performance); mixed glue can be used up at one time, avoiding waste and reducing procurement costs.
How to Use (Step-by-Step Guide)
- Pre-Mixing Preparation: Fully stir Component A in its container to mix the settled filler evenly, and shake Component B thoroughly to ensure uniform consistency, avoiding affecting curing effect, adhesion and dielectric performance, which is crucial for Zener diode voltage stabilization precision.
- Mixing: Mix Component A and Component B according to the specified weight ratio (customizable), stir slowly and evenly to avoid generating air bubbles, which may affect insulation, thermal stability and sealing performance of Zener diodes.
- Degassing (Optional): Put the mixed potting compound into a vacuum container, degas at 0.01MPa for 3 minutes to completely eliminate air bubbles, then pour it into Zener diode packaging molds or casings.
- Curing: Place the encapsulated Zener diode at room temperature for curing or heat to accelerate curing; enter the next process after basic curing, and full curing takes 24 hours. Note: Environment temperature and humidity significantly affect curing speed and final performance.
