Product details
Overview
BZD27B160P-HE3_A18 from Vishay Semiconductors is a surface-mount, AEC-Q101 qualified Zener diode with nominal breakdown voltage of 160 V, ±2 % tolerance, 5 mA test current, and 130 V clamping voltage at 5 A surge current. It delivers 150 W peak surge power (10/1000 μs), operates from −65 °C to +175 °C, and is used for overvoltage protection in automotive power rails and industrial DC bus lines.
For engineers reviewing the BZD27B160P-HE3_A18 datasheet, BZD27B160P-HE3_A18 pinout, BZD27B160P-HE3_A18 application, or BZD27B160P-HE3_A18 equivalent, key selection criteria include its 160 V Zener voltage tolerance, 130 V clamping performance under 5 A transient, AEC-Q101 qualification, SOD-123W-compatible DO-219AB package, and 175 °C maximum junction temperature.
Technical Context
This unidirectional Zener diode functions as a precision voltage reference and transient voltage suppressor. Its silicon planar construction ensures stable breakdown characteristics, low leakage (<1 μA at VR = 130 V), and tight ±2 % VZ tolerance across temperature.
The device features a low dynamic resistance of 150 Ω at IZT = 5 mA and a positive temperature coefficient of +0.09 to +0.13 %/°C - enabling predictable voltage drift in high-temperature environments such as engine control units and battery management systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A | TVS diode (not Zener); 160 V standoff, 219 V clamping at 5 A, 600 W peak power | Designed for fast transient suppression (response <1 ns); higher clamping but less precise regulation | Choose SMBJ160A when surge energy exceeds 150 W or sub-nanosecond response is required; not suitable for voltage reference use. |
| BZD27C160P-HE3_A18 | Same package and AEC-Q101 qualification; ±5 % VZ tolerance (152–168 V), 10 mA IZT | Looser tolerance reduces cost; higher test current increases self-heating in precision bias networks | Choose BZD27C160P-HE3_A18 where ±5 % VZ is acceptable and higher IZT does not impact thermal budget. |
Compared with BZD27B160P-HE3_A18, SMBJ160A offers higher surge capacity but lacks Zener regulation stability, while BZD27C160P-HE3_A18 trades voltage precision for cost and higher bias current - making the BZD27B160P-HE3_A18 optimal for applications requiring both AEC-Q101 compliance and ±2 % accuracy.

FAQ
What is the Zener voltage tolerance of BZD27B160P-HE3_A18?
The BZD27B160P-HE3_A18 has a guaranteed Zener voltage range of 156.8 V to 163.2 V at 5 mA test current, corresponding to a tight ±2 % tolerance around the nominal 160 V value. This specification is verified per the Vishay BZD27B Series datasheet Rev. 2.1 and applies under standard test conditions (TA = 25 °C).
Is BZD27B160P-HE3_A18 qualified for automotive applications?
Yes, BZD27B160P-HE3_A18 is explicitly AEC-Q101 qualified, as indicated by the "-HE3" suffix and confirmed in the Vishay datasheet. It meets requirements for ESD (HBM >8 kV), whisker resistance (JESD 201 Class 2), moisture sensitivity (MSL Level 1), and high-temperature operation up to 175 °C junction temperature.
What is the clamping voltage of BZD27B160P-HE3_A18 under surge conditions?
The BZD27B160P-HE3_A18 clamps to a maximum of 214 V at 5 A peak reverse current using the 10/1000 μs waveform, as specified in the Vishay datasheet Section 3, Table "Electrical Characteristics (Protection Mode)". This defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Which package does BZD27B160P-HE3_A18 use, and is it RoHS-compliant?
BZD27B160P-HE3_A18 uses the DO-219AB (SMF) surface-mount package, dimensionally compatible with SOD-123W footprints. It is RoHS-compliant per the "-HE3" designation and meets UL 94 V-0 flammability rating, with MSL Level 1 handling per J-STD-020.
Can BZD27B160P-HE3_A18 be used as a voltage reference in precision circuits?
Yes, BZD27B160P-HE3_A18 supports precision reference use due to its ±2 % VZ tolerance, low dynamic resistance (150 Ω), and stable temperature coefficient (+0.09 to +0.13 %/°C). However, its 5 mA test current and 175 °C max junction temperature require careful thermal design in bias networks.
