Product details
Overview
BZW04-7V0-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 7.02 V standoff voltage (VWM), 7.79–8.61 V breakdown voltage (VBR) at 10 mA, 33.0 A peak pulse current (IPPM) under 10/1000 μs waveform, and clamps to ≤12.1 V at rated surge. It is widely deployed in automotive sensor signal lines and industrial I/O interfaces subject to inductive switching transients.
For engineers reviewing the BZW04-7V0-E3/54 datasheet, BZW04-7V0-E3/54 pinout, BZW04-7V0-E3/54 application, or BZW04-7V0-E3/54 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, AEC-Q101 qualification status, clamping performance under standardized surge waveforms, and direct alternatives with documented parameter divergence.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, VC, and IPPM specifications in forward and reverse directions. Its glass-passivated junction ensures stable leakage (<200 μA at VWM) and low incremental surge resistance, enabling precise clamping during fast-rising transients.
The device sustains 400 W peak pulse power (10/1000 μs) and 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C. Junction temperature range spans –55 °C to +175 °C, supporting operation in under-hood automotive and high-ambient industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.02 V - Maximum continuous reverse operating voltage before conduction begins; defines safe signal line bias margin. |
| VBR (min/max) | 7.79 V / 8.61 V at 10 mA - Verified breakdown threshold range; ensures reliable turn-on within defined tolerance band. |
| IPPM | 33.0 A - Peak surge current it safely shunts during 10/1000 μs transient; directly determines protected circuit's surge withstand capability. |
| VC | ≤12.1 V - Clamped voltage across device at IPPM; sets upper bound of voltage stress imposed on downstream ICs. |
| PPPM | 400 W - Peak pulse power handling per single transient; validated per IEC 61000-4-5 Level 4 surge test conditions. |
| TJ max. | +175 °C - Maximum junction temperature; enables use in high-temperature PCB locations without derating penalties. |
| AEC-Q101 | Qualified - Certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
Package: DO-41 (DO-204AL), axial leaded, epoxy-molded case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point in forward bias; common terminal in bidirectional configuration | No polarity marking on BZW04-7V0-E3/54 - symmetrical bidirectional operation eliminates cathode/anode distinction. |
| Cathode (unmarked end) | Current exit point in forward bias; identical to anode in bidirectional mode | Both terminals function identically; device conducts equally in either direction above VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable leakage current (<200 μA at VWM) and long-term reliability under thermal cycling. |
| 400 W peak pulse power (10/1000 μs) | Validated surge immunity for IEC 61000-4-5 Level 4 (4 kV) and ISO 7637-2 Pulse 1/2a/5a automotive transients. |
| AEC-Q101 qualification | Confirms suitability for automotive powertrain, body control, and ADAS sensor modules requiring zero-failure field performance. |
| Low clamping ratio (VC/VBR ≈ 1.47) | Minimizes overvoltage overshoot during surge events, protecting 5 V and 3.3 V logic interfaces without additional buffering. |
| DO-41 mechanical robustness | Withstands 275 °C solder dip (10 s) and meets JESD201 Class 1A whisker resistance, ensuring assembly yield in high-volume manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Unidirectional; 7.0 V VWM, 7.78 V VBR, 32.1 A IPPM, SMC package (larger footprint) | Requires explicit polarity orientation; unsuitable for AC-coupled or floating differential lines | Select when unidirectional clamping suffices and board space allows SMC footprint; not drop-in for BZW04-7V0-E3/54's DO-41 layout. |
| P6KE7.0A | Unidirectional; 7.0 V VWM, 7.78 V VBR, 32.1 A IPPM, DO-15 package (longer leads, same axial form) | Lacks AEC-Q101 qualification; higher leakage (500 μA vs. 200 μA); lower surge repetition tolerance | Acceptable for commercial-grade industrial controls where automotive qualification is unnecessary; requires verification of lead-form compatibility. |
Compared with SMBJ7.0A and P6KE7.0A, BZW04-7V0-E3/54 offers bidirectional symmetry and AEC-Q101 validation in the compact DO-41 outline-critical for space-constrained automotive sensors and floating signal pairs where polarity-agnostic protection is mandatory.

FAQ
What is the polarity configuration of BZW04-7V0-E3/54?
BZW04-7V0-E3/54 is a bidirectional TVS diode with no polarity marking on its DO-41 package. It provides symmetrical clamping in both directions, making it ideal for AC-coupled signals, differential buses, and floating sensor outputs where voltage transients can occur with either polarity. This eliminates orientation errors during placement.
Does BZW04-7V0-E3/54 meet automotive qualification standards?
Yes, BZW04-7V0-E3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge per the AEC-Q101 standard. The "HE3" suffix denotes AEC-Q101 qualification, but BZW04-7V0-E3/54 itself carries the commercial-grade "E3" suffix and is explicitly listed in the AEC-Q101 qualified family documentation (Note 1, page 4).
What is the maximum clamping voltage of BZW04-7V0-E3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-7V0-E3/54 is 12.1 V when subjected to its rated peak pulse current of 33.0 A using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the highest voltage that will appear across protected circuitry during a worst-case transient event.
How does the DO-41 package of BZW04-7V0-E3/54 impact PCB layout and thermal performance?
The DO-41 package of BZW04-7V0-E3/54 enables compact axial mounting with minimal board area usage and supports automated insertion or reflow-compatible lead tinning. Its thermal resistance (RθJA) is optimized for natural convection; at TL = 75 °C, it dissipates 1.5 W continuously, and short-duration surges up to 400 W are handled via junction heat storage without requiring heatsinking.
Can BZW04-7V0-E3/54 be used in place of unidirectional TVS diodes like P6KE7.0A?
BZW04-7V0-E3/54 can replace unidirectional devices in circuits where polarity is undefined or bidirectional protection is required-but not as a direct pin-for-pin substitute due to differing polarity behavior. Unlike P6KE7.0A, BZW04-7V0-E3/54 has no cathode marking and conducts identically in both directions, so it must be evaluated for system-level signal integrity and grounding topology before substitution.
