Product details
Overview
BZD27B62P-HE3_A18 from Vishay Semiconductors is a surface-mount silicon planar Zener diode rated for 62 V nominal Zener voltage (60.76–63.24 V), 10 mA test current, and 150 W non-repetitive peak surge power (10/1000 μs waveform), designed for overvoltage protection in automotive power rails and industrial DC bus monitoring.
For engineers reviewing the BZD27B62P-HE3_A18 datasheet, BZD27B62P-HE3_A18 pinout, BZD27B62P-HE3_A18 application, or BZD27B62P-HE3_A18 equivalent, key selection criteria include its AEC-Q101 qualification, ±2 % VZ tolerance, low dynamic resistance (47 Ω max), temperature coefficient (0.08–0.13 %/°C), and DO-219AB (SMF) package compatibility with high-power transient suppression.
Technical Context
This unidirectional Zener diode operates as a precision voltage reference and transient voltage suppressor in clamping configurations. It delivers stable regulation under DC bias and robust surge handling per IEC 60-1 (10/1000 μs), with clamping voltage of 82.9 V at 5 A peak reverse current and junction temperature capability up to 175 °C.
Its thermal design supports 30 K/W junction-to-lead resistance and 180 K/W junction-to-ambient (on 3 mm × 3 mm Cu pads), enabling reliable operation in high-temperature automotive engine control units and industrial motor drives without forced cooling.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | TVS diode (not Zener); 64 V standoff, 100 W PPPM, bidirectional option available | Designed for faster transient response but lacks precision DC regulation capability | Select when surge speed dominates over DC accuracy; not suitable as voltage reference |

The BZD27B62P-HE3_A18 has a nominal Zener voltage of 62 V with a guaranteed range of 60.76 V to 63.24 V at 10 mA test current, corresponding to ±2 % tolerance per the BZD27B Series specification. This tight tolerance enables accurate voltage clamping and reference applications in automotive and industrial systems where regulation stability is essential. The BZD27B62P-HE3_A18 achieves this via silicon planar process control and 100 % parametric screening.
Is the BZD27B62P-HE3_A18 suitable for automotive applications?
Yes, the BZD27B62P-HE3_A18 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. It meets JESD 201 Class 2 whisker testing, MSL Level 1 moisture sensitivity, and 8 kV HBM ESD robustness. Its 175 °C maximum junction temperature and 150 W surge rating make the BZD27B62P-HE3_A18 appropriate for engine control units, battery management systems, and ADAS power supplies.
What package does the BZD27B62P-HE3_A18 use, and is it RoHS-compliant?
The BZD27B62P-HE3_A18 uses the DO-219AB (SMF) surface-mount package - a low-profile, thermally efficient case with 2.7–2.9 mm length and 1.7–1.9 mm width. It is RoHS-compliant and halogen-free, with UL 94 V-0 molded compound. The "HE3" suffix confirms AEC-Q101 qualification and RoHS compliance, and the device is compatible with standard SOD-123W/SOD-123F footprints. The BZD27B62P-HE3_A18 supports wave and reflow soldering up to 260 °C peak.
How does the BZD27B62P-HE3_A18 perform under surge conditions?
The BZD27B62P-HE3_A18 withstands 150 W non-repetitive peak surge power per 10/1000 μs waveform (IEC 60-1), with clamping voltage limited to 82.9 V at 5 A peak reverse current. Its thermal impedance (RthJA = 180 K/W on 3 mm × 3 mm Cu pads) and junction-to-lead resistance (30 K/W) ensure safe energy dissipation without thermal runaway. This surge performance makes the BZD27B62P-HE3_A18 ideal for protecting sensitive electronics from load dump and inductive switching events.
What is the maximum operating temperature for the BZD27B62P-HE3_A18?
The BZD27B62P-HE3_A18 has a maximum junction temperature (Tj) of 175 °C and an operating temperature range of -65 °C to +175 °C. Its storage temperature range matches this span. This wide thermal capability enables use in high-ambient environments such as automotive engine compartments and industrial motor drive cabinets. Derating curves in the datasheet confirm 800 mW power dissipation at 30 °C ambient and 2300 mW at lead temperature (TL) = 105 °C - both validated for the BZD27B62P-HE3_A18.
