Product details
Overview
BZW04P6V4B-E3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 6.4 V stand-off voltage (VWM), 11.3 V clamping voltage (VC) at 35.4 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - ideal for safeguarding MOSFETs, ICs, and sensor signal lines against inductive switching transients.
For engineers reviewing the BZW04P6V4B-E3/54 datasheet, BZW04P6V4B-E3/54 pinout, BZW04P6V4B-E3/54 application, or BZW04P6V4B-E3/54 equivalent, key selection criteria include its DO-204AL (DO-41) axial package, bi-directional symmetry, AEC-Q101 qualification, low clamping ratio (VC/VWM ≈ 1.77), and 0.061 %/°C breakdown voltage temperature coefficient.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: during transient events exceeding its breakdown voltage (VBR = 7.13–8.25 V), it rapidly avalanches to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns).
Rated for 400 W peak pulse power under 10/1000 μs waveform with 0.01 % duty cycle, it sustains repetitive surges while maintaining thermal stability up to TJ = 175 °C. The bi-directional configuration eliminates polarity concerns in AC-coupled or differential signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.4 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 5 V logic/sensor rails. |
| VBR (min/max) | 7.13 V / 8.25 V at 10 mA - precise avalanche onset range ensuring reliable triggering without premature conduction. |
| VC @ IPPM | 11.3 V at 35.4 A - clamping voltage limits protected circuit stress during worst-case 400 W transient; VC/VWM = 1.77. |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform; enables protection against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | 500 μA - maximum reverse leakage at 6.4 V; low enough to avoid loading sensitive analog or high-impedance inputs. |
| TJ max. | 175 °C - maximum junction temperature supports operation in under-hood automotive and industrial environments. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
Pinout & Package
Package: DO-204AL (DO-41), 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. No polarity marking - bi-directional symmetry confirmed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction terminals | No functional distinction; either end connects to protected line or ground - enables single-component placement on AC or floating nodes. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A | Uni-directional; 6.0 V VWM; DO-214AA package; 600 W PPPM; higher VF (3.5 V) | Requires polarity-aware layout; better suited for DC-biased rails where forward conduction may occur. | Select when higher pulse power is needed and unidirectional operation is acceptable. |
| P6KE6.8A | Uni-directional; 6.8 V VWM; DO-15 package; 600 W PPPM; larger footprint; no AEC-Q101 qualification | Larger mechanical size limits PCB density; lacks automotive qualification and tighter VBR tolerance. | Choose for cost-sensitive industrial designs where AEC-Q101 is not required and board space permits. |
Compared with SMBJ6.0A and P6KE6.8A, BZW04P6V4B-E3/54 offers bi-directional symmetry in a compact DO-41 package with AEC-Q101 validation - making it optimal for space-constrained, polarity-agnostic, and automotive-grade protection where clamping precision and reliability are critical.

FAQ
What is the clamping voltage of BZW04P6V4B-E3/54 and how does it protect downstream components?
The BZW04P6V4B-E3/54 has a maximum clamping voltage (VC) of 11.3 V at 35.4 A peak pulse current. This means that during a transient event, the device limits the voltage seen by downstream components to ≤11.3 V - well below typical 15 V absolute maximum ratings of 5 V logic ICs and MOSFETs. Its fast avalanche response (<1 ns) ensures minimal overshoot, preserving signal integrity and preventing latch-up or gate oxide damage in protected circuits.
Is BZW04P6V4B-E3/54 suitable for automotive applications?
Yes, BZW04P6V4B-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. It meets rigorous stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD robustness per JESD22-A114. Its 175 °C maximum junction temperature and DO-204AL package with matte tin leads support under-hood and body-control module deployments where thermal and mechanical reliability are essential.
How does the bi-directional design of BZW04P6V4B-E3/54 affect circuit layout?
The bi-directional nature of BZW04P6V4B-E3/54 eliminates polarity constraints: either lead can connect to the protected line or ground. This simplifies PCB layout for AC-coupled signals, differential buses (e.g., RS-485, CAN), or floating references. Unlike uni-directional TVS diodes, no cathode band marking is present - reducing assembly errors and enabling single-BOM usage across multiple signal types.
What is the significance of the "E3/54" suffix in BZW04P6V4B-E3/54?
The "E3" denotes RoHS-compliant, commercial-grade packaging per JESD201 Class 1A whisker testing; "54" specifies the preferred package code for 13-inch paper tape and reel delivery (550 units per reel). This ordering format ensures traceable, standardized logistics and compatibility with automated SMT placement equipment - critical for high-volume manufacturing of BZW04P6V4B-E3/54 into automotive and industrial assemblies.
Can BZW04P6V4B-E3/54 be used in place of a uni-directional TVS like SMBJ6.0A?
BZW04P6V4B-E3/54 is not a direct replacement for uni-directional TVS diodes such as SMBJ6.0A in DC-biased circuits where forward conduction occurs, because it conducts equally in both directions. However, it is functionally superior in AC, differential, or floating-node applications - offering identical VWM and VC performance without polarity sensitivity. Always verify circuit topology and bias conditions before substitution.
