Product details
Overview
BZW04P11B-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 11.1 V stand-off voltage (VWM), 12.4–14.3 V breakdown voltage (VBR), 18.2 V clamping voltage (VC) at 22 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04P11B-E3/54 datasheet, BZW04P11B-E3/54 pinout, BZW04P11B-E3/54 application, or BZW04P11B-E3/54 equivalent, key selection criteria include its bi-directional clamping behavior, AEC-Q101 qualification, DO-41 package compatibility, and low 0.081 %/°C VBR temperature coefficient for stable performance across thermal environments.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, delivering consistent clamping during positive and negative transients without polarity marking. Its glass-passivated junction ensures fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
The device complies with AEC-Q101 for automotive-grade reliability and meets UL 94 V-0 flammability requirements via its molded epoxy DO-204AL (DO-41) package. Thermal derating follows a defined curve up to TJ = 175 °C, with power dissipation limited to 1.5 W on infinite heatsink at TL = 75 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | DO-214AA (SMB) package, 11.1 V VWM, 18.2 V VC at 21.5 A, same 400 W PPPM but higher thermal resistance | Surface-mount alternative requiring PCB re-layout; better suited for high-density consumer boards than through-hole industrial designs | Select SMBJ11CA only when SMT assembly and space constraints outweigh through-hole serviceability needs. |
| P6KE11CA | DO-15 package, identical VWM/VC ratings but lower 600 W PPPM (10/1000 µs), larger body size, non-AEC-Q101 | Legacy industrial replacement where AEC-Q101 is not required and higher surge margin is acceptable | Choose P6KE11CA for cost-sensitive non-automotive applications where DO-15 mounting is already standardized. |
Compared with BZW04P11B-E3/54, SMBJ11CA offers SMT compatibility but sacrifices mechanical robustness and thermal cycling endurance, while P6KE11CA provides higher surge headroom at the expense of automotive qualification and modern RoHS compliance.

FAQ
What is the clamping voltage of BZW04P11B-E3/54 under maximum surge conditions?
The BZW04P11B-E3/54 exhibits a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 22 A with a 10/1000 µs waveform. This value is measured per IEC 61000-4-5 and defines the upper voltage limit imposed on protected circuitry during transient events. The BZW04P11B-E3/54 maintains this clamping performance across its full operating temperature range.
Is BZW04P11B-E3/54 suitable for automotive applications?
Yes, BZW04P11B-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control, body electronics, and sensor interfaces. Its construction - glass-passivated junction, DO-41 package with UL 94 V-0 epoxy, and 175 °C maximum junction temperature - meets stringent automotive reliability requirements. The BZW04P11B-E3/54 is listed in Vishay's AEC-Q101 qualified product matrix.
Does BZW04P11B-E3/54 have polarity markings?
No, BZW04P11B-E3/54 is a bi-directional TVS diode and carries no polarity marking on its DO-41 package. Both leads are functionally identical, allowing installation without orientation concerns. This symmetry supports simplified layout and eliminates risk of reverse installation - a key advantage over uni-directional variants like BZW04P11-E3/54, which feature a cathode band.
What is the maximum reverse leakage current for BZW04P11B-E3/54 at its stand-off voltage?
The BZW04P11B-E3/54 specifies a maximum reverse leakage current (ID) of 1.0 µA at its 11.1 V stand-off voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage ensures minimal power loss and signal distortion in high-impedance sensing and communication lines. The BZW04P11B-E3/54 maintains leakage below 5 µA up to 125 °C per Vishay's derating curves.
How does the temperature coefficient affect BZW04P11B-E3/54's breakdown voltage?
The BZW04P11B-E3/54 has a maximum temperature coefficient of +0.081 %/°C for its breakdown voltage (VBR), meaning VBR increases predictably with junction temperature. For example, at 125 °C, VBR rises by approximately 0.81 V above its 25 °C value - critical for designing margin into clamping thresholds in thermally aggressive environments. This coefficient is tightly controlled and verified per lot for the BZW04P11B-E3/54.
