Product details
Overview
PLZ9V1C-HG3_A/H from Vishay Semiconductors is an AEC-Q101-qualified silicon planar Zener diode in MicroSMF (DO-219AC) package, delivering 8.83–9.30 V nominal zener voltage at 20 mA test current, 7.4 V reverse clamping voltage at 8 A peak pulse current, and ≥30 kV ESD immunity per IEC 61000-4-2. It serves precision voltage regulation and transient suppression in automotive power rails and sensor interfaces.
For engineers reviewing the PLZ9V1C-HG3_A/H datasheet, PLZ9V1C-HG3_A/H pinout, PLZ9V1C-HG3_A/H application, or PLZ9V1C-HG3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 7.4 V clamping performance at 8 A, 130 K/W junction-to-ambient thermal resistance, and MicroSMF footprint compatibility with high-density PCB layouts.
Technical Context
The PLZ9V1C-HG3_A/H operates as a single-element, unidirectional Zener diode optimized for stable voltage reference and overvoltage protection. Its design incorporates low dynamic resistance (6.0 Ω at 20 mA), ultra-low leakage (<0.5 μA at VR), and robust surge capability (70 W non-repetitive peak power per IEC 61000-4-5 8/20 μs waveform).
Manufactured using silicon planar technology, it achieves excellent long-term stability and tight zener voltage tolerance (±2.6% across 8.83–9.30 V range). The device supports wave and reflow soldering per J-STD-020 and IEC 61760-1, with MSL level 1 rating and 260 °C / 10 s terminal soldering tolerance.

The PLZ9V1C-HG3_A/H has a nominal zener voltage range of 8.83 V to 9.30 V at 20 mA test current, representing a ±2.6% tolerance about the 9.1 V center value. This tight specification ensures consistent regulation performance across production lots and temperature ranges, critical for automotive sensor reference applications where accuracy directly impacts system calibration.
Is PLZ9V1C-HG3_A/H qualified for automotive use?
Yes, PLZ9V1C-HG3_A/H is explicitly AEC-Q101 qualified, as indicated by the "HG3" suffix in its ordering code. It undergoes rigorous stress testing-including high-temperature reverse bias, temperature cycling, and ESD-to ensure reliability in automotive environments such as engine bays and body control modules operating from −40 °C to +125 °C junction temperature.
What is the maximum peak pulse current PLZ9V1C-HG3_A/H can handle?
The PLZ9V1C-HG3_A/H supports a maximum peak pulse current (IPPM) of 8 A under 8/20 μs waveform per IEC 61000-4-5, corresponding to 70 W non-repetitive surge power dissipation. This rating applies specifically to variants from PLZ2V7A through PLZ4V7C, confirming its suitability for protecting 9 V rails against ISO 7637-2 and IEC 61000-4-5 Level 4 transients.
Does PLZ9V1C-HG3_A/H have a specified clamping voltage?
Yes, the PLZ9V1C-HG3_A/H has a reverse clamping voltage (VC) of 7.4 V at IPPM = 8 A. This value is measured under standardized 8/20 μs surge conditions and defines the maximum voltage seen by downstream circuitry during transient events-enabling accurate overvoltage margining for 5 V or 3.3 V logic components powered from the protected rail.
What package type does PLZ9V1C-HG3_A/H use, and what are its key mechanical features?
PLZ9V1C-HG3_A/H uses the MicroSMF (DO-219AC) package: dimensions 2.5 ± 0.1 mm × 1.3 ± 0.1 mm × 0.6 ± 0.1 mm, cathode marked by bar, MSL level 1, UL 94 V-0 flammability rating.
