Product details
Overview
BZD27B6V2P-HE3_A08 from Vishay Semiconductors is a surface-mount, AEC-Q101 qualified Zener diode with nominal breakdown voltage 6.2 V, ±2 % tolerance, 100 mA test current, 3 Ω dynamic resistance, and -0.01 to +0.06 %/°C temperature coefficient - used for precision voltage regulation and overvoltage protection in automotive power rails.
For engineers reviewing the BZD27B6V2P-HE3_A08 datasheet, BZD27B6V2P-HE3_A08 pinout, BZD27B6V2P-HE3_A08 application, or BZD27B6V2P-HE3_A08 equivalent, key selection criteria include its 150 W peak surge power rating (10/1000 μs), 175 °C max junction temperature, SOD-123W-compatible DO-219AB package, and low leakage (5 μA at 5 V reverse).
Technical Context
This unidirectional Zener diode operates in reverse-bias breakdown mode with tightly controlled voltage regulation. Its silicon planar construction ensures excellent long-term stability and low leakage current (≤5 μA at VR = 5 V), while the AEC-Q101 qualification confirms suitability for automotive environments including under-hood applications.
The device features a low-profile DO-219AB (SMF) package with MSL level 1 moisture sensitivity and JESD 201 Class 2 whisker resistance. Thermal performance is defined by RthJA = 180 K/W on 3 mm × 3 mm Cu pads and RthJL = 30 K/W, enabling robust surge handling up to 150 W (PRSM) and 300 W (PZSM) for short pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage (VZ) | 6.08–6.32 V at 100 mA - enables stable reference in 5 V–6.5 V rail monitoring circuits |
| Dynamic resistance (ZZ) | 3 Ω max at IZT = 100 mA - ensures minimal output voltage variation under load transients |
| Temperature coefficient (αVZ) | -0.01 to +0.06 %/°C - supports stable regulation across -65 to +175 °C operating range |
| Peak surge power (PRSM) | 150 W (10/1000 μs waveform) - protects against ISO 7637-2 pulse 1/2a/3a-induced transients |
| Reverse leakage (IR) | 5 μA max at VR = 5 V - minimizes standby power loss in always-on automotive modules |
| Junction-to-ambient thermal resistance | 180 K/W on 3 mm × 3 mm Cu pad - defines maximum continuous power dissipation (800 mW at TA = 30 °C) |
| ESD rating (HBM) | >8 kV - meets stringent automotive ESD immunity requirements per AEC-Q101 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2LT1G | Higher ZZ (10 Ω typ.), ±5 % VZ, SOT-23 package, 350 mW Ptot | Limited to low-power consumer applications; not AEC-Q101 qualified | Select when cost-sensitive non-automotive designs require smaller footprint and lower surge capability |
| PZM6.2NB,115 | Same 6.2 V nominal, ±2 %, but TO-236AB (SOT-23) package, 500 mW Ptot, no AEC-Q101 | Lower thermal mass limits surge handling; unsuitable for under-hood temperature cycling | Choose for industrial PCBs where DO-219AB height constraint is absent and automotive qualification is unnecessary |
Compared with BZX84-C6V2LT1G and PZM6.2NB,115, the BZD27B6V2P-HE3_A08 delivers superior surge resilience (150 W vs. <10 W), automotive-grade reliability (AEC-Q101), and thermal robustness (175 °C TJmax), making it the only suitable choice for safety-critical vehicle subsystems.
