Product details
Overview
PLZ15C-HG3_A/H from Vishay Semiconductors is a silicon planar Zener diode in the AEC-Q101-qualified MicroSMF (DO-219AC) package, delivering 14.35 V to 15.09 V nominal zener voltage at 10 mA test current, 4.50 Ω dynamic resistance, and 22.0 A peak pulse current for transient suppression in automotive power rails.
For engineers reviewing the PLZ15C-HG3_A/H datasheet, PLZ15C-HG3_A/H pinout, PLZ15C-HG3_A/H application, or PLZ15C-HG3_A/H equivalent, this device serves as a precision voltage reference and ESD/surge clamp in space-constrained, high-reliability automotive control modules, infotainment power supplies, and ADAS sensor interfaces.
Technical Context
The PLZ15C-HG3_A/H operates as a single-element, unidirectional Zener diode optimized for stable voltage regulation under reverse bias. Its design integrates low leakage (<0.2 μA at VR), high ESD immunity (≥30 kV per IEC 61000-4-2), and robust surge capability (70 W for 8/20 μs transients).
Thermally, it features a junction-to-ambient thermal resistance of 130 K/W on FR4 and junction-to-lead resistance of 40 K/W, enabling reliable operation up to 150 °C junction temperature with 500 mW power dissipation at 85 °C ambient.

FAQ
What is the exact zener voltage tolerance of PLZ15C-HG3_A/H at 10 mA test current?
The PLZ15C-HG3_A/H has a guaranteed zener voltage range of 14.35 V minimum to 15.09 V maximum at 10 mA test current (IZT), representing a ±2.5% tolerance around the nominal 15 V rating. This specification is verified per the Vishay PLZ Series datasheet Rev. 1.7 and applies strictly to the PLZ15C-HG3_A/H variant with HG3_A/H suffix indicating AEC-Q101 qualification and green RoHS compliance.
Is PLZ15C-HG3_A/H suitable for use in a 12 V automotive system experiencing load dump transients?
Yes, the PLZ15C-HG3_A/H is explicitly rated for 70 W peak pulse power (8/20 μs per IEC 61000-4-5) and clamps at 22.0 V (VC) under 22.0 A peak current, making it suitable for suppressing load dump transients in 12 V systems. Its AEC-Q101 qualification and 150 °C junction rating further confirm its suitability for under-hood deployment in conjunction with appropriate series impedance.
Does PLZ15C-HG3_A/H have a defined forward voltage specification?
Yes, the PLZ15C-HG3_A/H specifies a forward voltage (VF) of 0.8 V minimum and 0.9 V maximum at 10 mA forward current, per the Electrical Specifications table in the Vishay PLZ Series datasheet. This VF value is relevant for polarity-check circuits and low-voltage drop applications where the diode may conduct in forward bias during fault conditions.
What is the moisture sensitivity level (MSL) and reflow profile compliance for PLZ15C-HG3_A/H?
The PLZ15C-HG3_A/H is rated MSL level 1 per J-STD-020, meaning it is not moisture-sensitive and can be stored indefinitely at ambient conditions without baking. It is qualified for standard lead-free reflow profiles (up to 260 °C peak, 10 s duration at terminals) and double-wave soldering per IEC 61760-1, as confirmed in the Package Characteristics section of the official datasheet.
How does the dynamic resistance of PLZ15C-HG3_A/H impact its regulation performance?
The PLZ15C-HG3_A/H exhibits a typical dynamic resistance (ZZ) of 4.50 Ω at 10 mA test current, which directly determines how much the zener voltage shifts under varying load current. For example, a 10 mA change in zener current results in only ~45 mV variation in output voltage-enabling precise regulation in feedback networks and reference circuits where stability under dynamic load is essential for the PLZ15C-HG3_A/H's intended automotive applications.
