Product details
Overview
BZW04-5V8B-E3/54 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 5.8 V stand-off voltage (VWM), 6.45–7.14 V breakdown voltage (VBR) at 10 mA, 10.5 V maximum clamping voltage (VC) at 38 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - ideal for protecting I/O interfaces and sensor signal lines in automotive and industrial control systems.
For engineers reviewing the BZW04-5V8B-E3/54 datasheet, BZW04-5V8B-E3/54 pinout, BZW04-5V8B-E3/54 application, or BZW04-5V8B-E3/54 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.55), AEC-Q101 qualification, DO-41 mechanical compatibility, and ≤1000 μA reverse leakage at VWM - critical for low-power sensor node and CAN/LIN bus protection designs.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients without polarity marking. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, enabling consistent clamping performance across repetitive 10/1000 μs surges at 0.01% duty cycle.
The BZW04-5V8B-E3/54 delivers 400 W peak pulse power dissipation with 38 A IPPM and 10.5 V VC, while maintaining TJ max. of 175 °C and operating down to –55 °C. Its 0.057 %/°C VBR temperature coefficient ensures predictable voltage threshold drift over temperature in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.8 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 5 V logic/sensor rails. |
| VBR (min/max) | 6.45 V / 7.14 V at IT = 10 mA - verified breakdown range ensures reliable turn-on during ESD or load-dump events. |
| VC @ IPPM | 10.5 V at 38 A - clamping voltage limits downstream IC stress during 400 W transient; clamping ratio = 1.55. |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform; supports IEC 61000-4-5 Level 3 surge immunity. |
| ID @ VWM | 1000 μA - reverse leakage at stand-off voltage; low enough to avoid signal integrity degradation in high-impedance sensor paths. |
| TJ max. | 175 °C - extended junction temperature rating enables use in under-hood automotive and industrial motor drive environments. |
| AEC-Q101 | Qualified - validated 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. No polarity marking - bidirectional operation confirmed by "B" suffix.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No functional distinction between leads; either terminal serves as cathode or anode depending on transient polarity - eliminates orientation errors during placement. |
| Lead 1 | External connection point | Matte tin-plated copper alloy lead; supports wave/solder reflow up to 275 °C for 10 s (JESD 22-B106). |
| Lead 2 | External connection point | Identical to Lead 1; symmetrical construction allows PCB layout flexibility and eliminates need for silkscreen polarity indicators. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable, repeatable avalanche characteristics over lifetime and temperature; prevents parameter drift due to moisture or contamination. |
| 400 W peak pulse power (10/1000 μs) | Withstands repeated surge events per IEC 61000-4-5 without degradation - suitable for industrial PLC backplane and automotive body electronics. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules, infotainment I/O, and ADAS sensor interfaces requiring long-term reliability. |
| Low clamping ratio (VC/VBR ≈ 1.55) | Minimizes voltage overshoot during fast transients - protects 5 V-tolerant microcontrollers and analog front-ends without additional series impedance. |
| DO-41 mechanical compatibility | Standard footprint enables drop-in replacement for legacy TVS diodes; supports automated insertion and reflow processes 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 |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Unidirectional; 5.0 V VWM; SMB package (surface-mount); 600 W PPPM; higher capacitance (~500 pF). | Requires polarity-aware layout; better suited for board-level space-constrained designs with higher surge margin needs. | Select when surface-mount assembly and ≥600 W surge rating are required; not pin-compatible due to package and polarity. |
| P6KE6.8CA | DO-15 package; same bidirectional function; 6.8 V VWM; 600 W PPPM; 11.5 V VC at 35 A; higher leakage (5000 μA). | Larger DO-15 footprint; higher clamping voltage reduces margin for 5 V systems; higher leakage may affect ultra-low-power sensor nodes. | Consider for cost-sensitive industrial applications where 11.5 V clamping is acceptable and DO-15 mounting is available. |
Compared with BZW04-5V8B-E3/54, SMBJ5.0A-E3/52 offers higher surge rating but requires polarity management and increases board area via larger package, while P6KE6.8CA trades lower clamping precision and higher leakage for broader availability - making BZW04-5V8B-E3/54 optimal for AEC-Q101-compliant, space-efficient 5 V bidirectional protection.

FAQ
What is the clamping voltage of BZW04-5V8B-E3/54 at its rated peak pulse current?
The BZW04-5V8B-E3/54 has a maximum clamping voltage (VC) of 10.5 V at 38 A peak pulse current (IPPM), measured using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and confirms effective overvoltage limiting for 5 V system rails. The clamping occurs symmetrically in both directions due to its bidirectional construction.
Is BZW04-5V8B-E3/54 qualified for automotive applications?
Yes, BZW04-5V8B-E3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22-A114. This qualification validates its suitability for automotive subsystems such as body control modules, sensor interfaces, and infotainment I/O - where reliability under thermal and electrical stress is mandatory.
Does BZW04-5V8B-E3/54 have polarity markings on the package?
No, BZW04-5V8B-E3/54 has no polarity markings because it is a bidirectional TVS diode. The "B" suffix explicitly denotes bidirectional functionality, and the DO-41 package features symmetrical leads with identical electrical behavior in either orientation - eliminating risk of incorrect placement during assembly.
What is the maximum reverse leakage current for BZW04-5V8B-E3/54 at its stand-off voltage?
At the 5.8 V stand-off voltage (VWM), the BZW04-5V8B-E3/54 exhibits a maximum reverse leakage current (ID) of 1000 μA at 25 °C. This value remains within specification across the full operating temperature range and is low enough to avoid loading effects on high-impedance sensor outputs or battery-powered circuits.
Can BZW04-5V8B-E3/54 be used in place of unidirectional TVS diodes like BZW04-5V8-E3/54?
No - BZW04-5V8B-E3/54 is strictly bidirectional and cannot replace unidirectional variants such as BZW04-5V8-E3/54 in circuits requiring forward conduction or DC blocking in one direction. Unidirectional types feature a cathode band and conduct forward current; substituting the bidirectional version would compromise circuit functionality in rectifier or polarity-sensitive protection schemes.
