Product details
Overview
BZW04P14B-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 13.6 V stand-off voltage (VWM), 22.5 V maximum clamping voltage (VC) at 17.8 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - suitable for protecting MOSFETs, sensor interfaces, and microcontroller I/O in industrial control systems.
For engineers reviewing the BZW04P14B-E3/54 datasheet, BZW04P14B-E3/54 pinout, BZW04P14B-E3/54 application, or BZW04P14B-E3/54 equivalent, key selection criteria include its bi-directional clamping symmetry, AEC-Q101 qualification, DO-41 package compatibility, low 0.086 %/°C VBR temperature coefficient, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity standards.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, delivering identical clamping performance regardless of transient polarity - critical for AC-coupled or floating signal paths. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM), while the 175 °C max junction temperature supports operation in high-ambient environments such as automotive engine compartments and industrial motor drives.
The device uses a 10/1000 μs double-exponential surge waveform standard per ANSI/IEEE C62.35, with derating applied above 25 °C ambient per Figure 2. Its 1.5 W steady-state power dissipation (PD) and 0.35 g unit weight align with DO-204AL (DO-41) mechanical constraints and thermal management requirements for through-hole PCB layouts.
Key Specifications

|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in engine control units exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed between sensor output and MCU ADC input, shunting transients before they reach precision amplifier stages. Use Value: Maintains signal integrity by limiting clamped voltage to 22.5 V while surviving >100,000 surge cycles per ISO 16750-2, eliminating field failures due to ESD-induced ADC saturation. |
Use Scenario: Safeguarding 24 V digital input modules in programmable logic controllers against inductive kickback from solenoid valves and contactors. IC Role / Device Role / Timing Role: Primary overvoltage suppression element on each isolated input channel, positioned upstream of optocoupler input diodes. Use Value: Prevents optocoupler damage by clamping 1 kV/2 Ω surges to ≤22.5 V within <1 ns response time, ensuring uninterrupted machine control during factory floor switching events. |
| Consumer Audio Line Protection | Telecom DSL Line Interface |
Use Scenario: Shielding balanced audio outputs (e.g., XLR, TRS) in professional mixers from ESD and cable discharge events during live setup. IC Role / Device Role / Timing Role: Symmetrical TVS pair (one per line) referenced to ground, providing common-mode and differential-mode transient suppression. Use Value: Eliminates audible pop/crackle during hot-plug by clamping ±8 kV contact ESD (IEC 61000-4-2) to <25 V, preserving dynamic range and preventing DAC latch-up. |
Use Scenario: Front-end protection for ADSL/VDSL line drivers and receivers exposed to lightning-induced surges on outside plant copper pairs. IC Role / Device Role / Timing Role: First-stage surge limiter in hybrid coupler interface, absorbing energy before it reaches transformer-coupled PHY ICs. Use Value: Withstands 10/700 μs telecom surges up to 1 kV (IEC 61000-4-5) with VC ≤22.5 V, enabling compliance with GR-1089-CORE and reducing need for secondary GDT stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ14CA | Same VWM (14.0 V), higher PPPM (600 W), SMC package (surface-mount), lower VC (23.2 V) | Requires PCB redesign for SMD placement; better suited for space-constrained consumer electronics vs. through-hole industrial boards | Select when board real estate is limited and automated assembly is preferred; verify thermal pad layout for 600 W surge dissipation. |
| P6KE15CA | Higher VWM (15.0 V), same DO-41 package, lower PPPM (600 W), higher VC (24.4 V), legacy series | Compatible footprint but looser VBR tolerance (±10 % vs. ±6.5 % for BZW04P14B); not AEC-Q101 qualified | Acceptable for cost-sensitive commercial designs where automotive qualification and tight parametric control are not required. |
Compared with SMBJ14CA and P6KE15CA, BZW04P14B-E3/54 offers tighter VBR tolerance, AEC-Q101 validation, and optimized thermal performance in DO-41 - making it preferable for automotive and high-reliability industrial deployments where long-term surge endurance and specification consistency are critical.

FAQ
What is the maximum clamping voltage of BZW04P14B-E3/54 under a 10/1000 μs surge?
The BZW04P14B-E3/54 clamps to a maximum of 22.5 V when subjected to its rated 17.8 A peak pulse current (IPPM) using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures downstream components like 3.3 V or 5 V MCUs remain within safe voltage limits during surge events.
Is BZW04P14B-E3/54 suitable for automotive applications?
Yes, BZW04P14B-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its 175 °C maximum junction temperature, glass-passivated junction, and validated performance under temperature cycling, humidity, and surge stress make it appropriate for engine control units, body electronics, and ADAS sensor interfaces where reliability under harsh conditions is mandatory.
Does BZW04P14B-E3/54 have polarity markings on the package?
No, BZW04P14B-E3/54 is a bi-directional TVS diode and carries no polarity marking - there is no cathode band or other visual indicator. The device functions identically in either orientation, simplifying assembly and eliminating risk of reverse installation in AC-coupled or differential signal paths.
What is the standoff voltage (VWM) and why does it matter for BZW04P14B-E3/54?
The standoff voltage VWM of BZW04P14B-E3/54 is 13.6 V - the maximum continuous DC or RMS voltage the device can block without entering avalanche conduction. This parameter defines the upper limit of normal operating voltage in the protected circuit; exceeding VWM risks premature clamping and increased leakage, so proper margin (e.g., ≥20 % above nominal rail) must be maintained in design.
How does the temperature coefficient affect BZW04P14B-E3/54 performance?
BZW04P14B-E3/54 has a maximum temperature coefficient of 0.086 %/°C for its breakdown voltage VBR. This means VBR increases by up to 0.086 % per degree Celsius rise in junction temperature - resulting in a predictable, modest upward shift in clamping threshold under thermal stress, which preserves system-level surge margin without unexpected turn-on or failure.
