• Store in dry conditions (<40°C and <90% RH) in original packaging.
• Use proper ESD precautions during handling and installation.
• Follow J-STD-020 guidelines for reflow soldering profiles.
• Clean with isopropyl alcohol if contamination occurs; avoid ultrasonic cleaning.

Design Considerations

When incorporating the BRY62 into circuit designs:

• Include current-limiting resistors where appropriate to prevent excessive I_GT.
• Ensure proper gate drive circuitry for reliable triggering.
• Consider snubber circuits for inductive load applications.
• Maintain clearance and creepage distances per IEC 60950 for safety-critical designs.
