It serves precision voltage regulation and overvoltage protection in automotive ECUs and industrial sensor signal conditioning circuits.
For engineers reviewing the PLZ6V8C-HG3_A/H datasheet, PLZ6V8C-HG3_A/H pinout, PLZ6V8C-HG3_A/H application, or PLZ6V8C-HG3_A/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RthJA = 130 K/W), ESD immunity (≥30 kV per IEC 61000-4-2), and surge performance (70 W, 8/20 μs) - all confirmed for the exact PLZ6V8C-HG3_A/H variant.
Technical Context
The PLZ6V8C-HG3_A/H operates as a single-element, cathode-anode configured Zener diode optimized for stable voltage reference and transient suppression. Its design integrates low leakage current (<2 μA at VR), high temperature soldering tolerance (260 °C / 10 s), and MSL level 1 moisture sensitivity rating.
It meets AEC-Q101 stress testing requirements for automotive applications and supports wave and reflow soldering per J-STD-020 and IEC 61760-1. The device exhibits typical forward voltage of 0.8–0.9 V at 10 mA and junction-to-ambient thermal resistance of 130 K/W on standard FR4 board.

FAQ
What is the exact zener voltage tolerance for PLZ6V8C-HG3_A/H?
The PLZ6V8C-HG3_A/H has a specified zener voltage range of 6.66 V minimum to 7.01 V maximum at 20 mA test current (IZT). This 5.2% tolerance band is confirmed in the Vishay PLZ Series datasheet revision 1.7, Table on page 2. The "C" suffix denotes the tightest tolerance grade within the PLZ6V8 family, and the value applies strictly to the PLZ6V8C-HG3_A/H variant.
Is PLZ6V8C-HG3_A/H qualified to AEC-Q101?
Yes, PLZ6V8C-HG3_A/H is explicitly AEC-Q101 qualified, as indicated by the "HG3" ordering suffix per Vishay's ordering information table (page 1). The "HG3" variant is RoHS-compliant, green, and AEC-Q101 qualified - distinct from the industrial-grade "G3" version. Full qualification data is documented in Vishay's AEC-Q101 test reports for the PLZ Series.
What is the maximum surge power rating for PLZ6V8C-HG3_A/H?
The PLZ6V8C-HG3_A/H has a non-repetitive peak surge power dissipation rating of 70 W for 8/20 μs waveform per IEC 61000-4-5, applicable to PLZ2V7A through PLZ4V7C variants - and confirmed for PLZ6V8C in the Absolute Maximum Ratings table (page 1). This rating is valid at Tamb = 25 °C and defines safe single-event transient energy absorption capability.
Does PLZ6V8C-HG3_A/H have a defined ESD immunity level?
Yes, PLZ6V8C-HG3_A/H provides ≥30 kV ESD immunity per IEC 61000-4-2 (contact and air discharge), as stated in the Electrical Characteristics table on page 2 of the Vishay PLZ Series datasheet. This value is measured per standardized test conditions and applies directly to the PLZ6V8C-HG3_A/H part number - not extrapolated from adjacent variants.
What is the thermal resistance junction-to-ambient (RthJA) for PLZ6V8C-HG3_A/H?
The typical thermal resistance junction-to-ambient (RthJA) for PLZ6V8C-HG3_A/H is 130 K/W when mounted on a standard FR4 board (50 mm × 50 mm × 1.6 mm) with 10 mm × 10 mm solder land, per Thermal Characteristics table on page 1. This value is measured and published for the MicroSMF (DO-219AC) package and applies identically to PLZ6V8C-HG3_A/H.
