Product details
Overview
BZW04-15BHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 15.3 V stand-off voltage (VWM), 17.1–18.9 V breakdown voltage (VBR) at 1 mA test current, and 400 W peak pulse power (10/1000 μs waveform). Used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial control systems against ESD and inductive switching surges.
For engineers reviewing the BZW04-15BHE3/54 datasheet, BZW04-15BHE3/54 pinout, BZW04-15BHE3/54 application, or BZW04-15BHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, clamping performance at 16.0 A peak pulse current, thermal derating behavior, and direct replacement guidance for bidirectional TVS selection in harsh-environment designs.
Technical Context
This device operates as a symmetric, bidirectional avalanche diode with glass-passivated junction, enabling identical clamping in both polarities. Its 10/1000 μs waveform response supports IEC 61000-4-5 surge immunity up to Level 4 when properly laid out, and its low incremental surge resistance ensures minimal voltage overshoot during transient events.
Rated for -55 °C to +175 °C operating junction temperature, it sustains 1.5 W steady-state power dissipation at TL = 75 °C and meets JESD201 Class 2 whisker resistance (HE3 suffix). The DO-41 package provides mechanical robustness and UL 94 V-0 flammability compliance for high-reliability PCB mounting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | DO-214AA package; 15 V VWM; 24.4 V VC @ 16.3 A; 600 W PPPM; higher capacitance (~150 pF). | Surface-mount layout; better suited for high-density PCBs but requires reflow-compatible footprint and thermal relief design. | Select SMBJ15CA when board space is constrained and SMT assembly is preferred; verify thermal pad layout for 1.5 W dissipation. |
| P6KE15CA | DO-15 package; same VWM/VC specs; 600 W PPPM; slower response due to larger junction area; not AEC-Q101 qualified. | Legacy through-hole alternative; acceptable for non-automotive industrial use where qualification is not mandated. | Choose P6KE15CA only for cost-sensitive commercial equipment where AEC-Q101 is unnecessary and DO-41 footprint compatibility is retained. |
Compared with BZW04-15BHE3/54, SMBJ15CA offers higher surge rating and SMT compatibility but demands PCB redesign, while P6KE15CA retains through-hole fit but lacks automotive qualification and has inferior thermal response - making BZW04-15BHE3/54 the optimal choice for AEC-Q101-compliant, space-constrained, high-reliability bidirectional clamping.

FAQ
What is the clamping voltage of BZW04-15BHE3/54 under a 10/1000 μs surge?
The BZW04-15BHE3/54 clamps to a maximum of 25.2 V when subjected to its rated 16.0 A peak pulse current (IPPM) using the standardized 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 16-Sep-2021, Document Number 88316. The clamping voltage directly determines the maximum stress imposed on downstream ICs, making it critical for selecting appropriate voltage margins in protected circuits.
Is BZW04-15BHE3/54 suitable for automotive applications?
Yes, BZW04-15BHE3/54 is AEC-Q101 qualified (denoted by the HE3 suffix), meaning it has passed accelerated stress testing for automotive-grade reliability including high-temperature operating life, temperature cycling, and ESD robustness. It is routinely deployed in automotive body control modules, lighting drivers, and sensor interfaces where sustained operation from -40 °C to +125 °C ambient and immunity to load-dump transients are required.
What does the "B" and "HE3" suffix mean in BZW04-15BHE3/54?
The "B" suffix indicates a bidirectional configuration - the device provides symmetrical clamping in both polarities, with no cathode marking. The "HE3" suffix specifies RoHS-compliance plus AEC-Q101 qualification and JESD201 Class 2 whisker resistance. This distinguishes it from the commercial-grade "E3" variant and confirms suitability for automotive and high-reliability industrial use cases.
How does BZW04-15BHE3/54 compare to unidirectional TVS diodes like BZW04-15HE3/54?
BZW04-15BHE3/54 provides identical VWM (15.3 V), VBR (17.1–18.9 V), and VC (25.2 V) specs as its unidirectional counterpart but operates equivalently in both directions - essential for protecting AC-coupled lines, differential buses, or floating grounds. Unlike unidirectional versions, it requires no polarity-aware placement, simplifying layout and reducing assembly errors in bidirectional signal paths.
What is the maximum junction temperature rating for BZW04-15BHE3/54?
The BZW04-15BHE3/54 has a maximum junction temperature (TJ max) of +175 °C, enabling reliable operation in high-ambient environments such as engine compartments, motor drives, and enclosed industrial enclosures. This rating is validated per the Vishay datasheet and supports continuous operation at full power dissipation (1.5 W) when lead temperature (TL) is maintained at 75 °C, with derating applied above that temperature per Figure 5.
