A: Yes. PLZ36A-G3/H is a parametric equivalent with identical electrical specifications (36 V nominal Zener voltage, 500 mW power rating, ±3% tolerance, 75 Ohms maximum impedance) and mechanical packaging (DO-219AC surface mount). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between standard grade (G3/H) and automotive grade (HG3_A/H) variants?

A: Automotive grade variants (HG3_A/H) carry AEC-Q101 qualification, indicating compliance with automotive industry reliability and quality standards. Electrical and mechanical specifications are identical. Automotive grade variants are required for automotive applications; standard grade variants are suitable for general industrial and consumer applications.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format is a logistics and handling specification only. PLZ36D-HG3_A/H supplied in Cut Tape format has identical electrical and mechanical characteristics to equivalent parts supplied in Tape & Reel format.
