Product details
Overview
BZW04-15B-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 a 15.3 V standoff voltage (VWM), 17.1–18.9 V breakdown voltage (VBR) at 1 mA, 25.2 V clamping voltage (VC) at 16 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and microcontroller I/O in industrial control systems.
For engineers reviewing the BZW04-15B-E3/54 datasheet, BZW04-15B-E3/54 pinout, BZW04-15B-E3/54 application, or BZW04-15B-E3/54 equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified transient protector for bidirectional AC-coupled lines, low-voltage DC rails, and automotive sensor signal conditioning where fast response (<1 ns), low clamping ratio, and stable temperature coefficient (0.088 %/°C) are critical.
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 (<1 μA at VWM) and robust surge handling up to 175 °C junction temperature.
The device uses a DO-41 axial-leaded package with matte tin-plated leads compliant to J-STD-002 and JESD22-B102, rated for solder dip at 275 °C for 10 s, and meets UL 94 V-0 flammability. It is not intended for unidirectional rectification but exclusively for transient suppression in AC or dual-polarity DC paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15.3 V - maximum continuous working voltage before clamping begins; defines safe operating margin for 12 V nominal systems. |
| VBR (min/max) | 17.1 V / 18.9 V at 1 mA - precise breakdown threshold ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 25.2 V at 16 A - clamping voltage limits downstream component stress during 400 W transient surges. |
| IPPM | 16 A - peak pulse current capacity with 10/1000 μs waveform; supports IEC 61000-4-5 Level 3 surge immunity. |
| PPPM | 400 W - standardized peak pulse power rating enabling direct comparison across TVS families. |
| TJ max | 175 °C - high junction temperature rating allows operation in under-hood or enclosed industrial environments. |
| Temp. Coeff. | 0.088 %/°C - low VBR drift ensures stable clamping performance across automotive and industrial temperature ranges. |
Pinout & Package
DO-41 (DO-204AL) axial-leaded package: hermetically sealed glass passivated chip in molded epoxy housing, 0.205" (5.2 mm) body diameter, 0.107" (2.7 mm) lead diameter, 1.0" (25.4 mm) minimum overall length. No polarity marking - bidirectional symmetry eliminates cathode/anode orientation concerns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both leads function identically; no directional installation required - simplifies PCB layout and assembly for AC or floating lines. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable leakage (<1 μA), repeatable VBR, and long-term reliability under thermal cycling. |
| 400 W peak pulse power (10/1000 μs) | Meets IEC 61000-4-5 surge test requirements for industrial and automotive electronics without derating. |
| AEC-Q101 qualified | Validated for automotive applications including engine control modules, body electronics, and ADAS sensor interfaces. |
| UL 94 V-0 molding compound | Provides flame-retardant encapsulation essential for safety-critical industrial and transportation equipment. |
| Matte tin-plated leads | Ensures solderability per J-STD-002 and resistance to whisker growth (JESD201 Class 1A). |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt transients before reaching signal conditioning ICs. Use Value: Limits induced voltage to ≤25.2 V during 16 A surges, preserving integrity of 3.3 V/5 V microcontrollers and precision ADC front-ends. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers against inductive kickback from solenoids and contactors. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC input channels, coordinated with series current-limiting resistors and optocouplers. Use Value: Withstands repetitive 400 W pulses at 0.01% duty cycle, enabling reliable operation in factory automation with frequent switching cycles. |
| Consumer Audio Line Protection | Telecom DSL/ADSL Interface |
Use Scenario: Shielding line-level audio inputs (RCA, 3.5 mm) in AV receivers and smart speakers from ESD and cable-induced transients. IC Role / Device Role / Timing Role: Low-capacitance TVS placed between connector and op-amp buffer stage to avoid signal distortion. Use Value: Clamps sub-100 ns ESD events to <25.2 V while adding negligible capacitance - preserves wideband audio fidelity up to 20 kHz. |
Use Scenario: Protecting ADSL line drivers and SLIC interfaces in residential gateways from lightning-induced surges on twisted-pair telephone lines. IC Role / Device Role / Timing Role: First-stage transient suppressor on differential pair, upstream of isolation transformers and line interface ICs. Use Value: Symmetric bidirectional clamping maintains common-mode rejection ratio (CMRR) and prevents saturation of transformer-coupled analog front-ends. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | DO-214AA package, 15 V VWM, 24.4 V VC @ 16.3 A, same PPPM but surface-mount only. | Requires SMT reflow process; unsuitable for through-hole legacy designs or high-vibration mechanical mounting. | Select when board space is constrained and automated assembly is available; verify thermal pad layout for 1.5 W steady-state dissipation. |
| P6KE15CA | DO-15 package, 15 V VWM, 24.4 V VC @ 16.3 A, identical electrical specs but lower surge rating (600 W vs. 400 W peak). | Higher peak power capability suits infrequent high-energy surges; larger DO-15 body increases PCB footprint by ~30%. | Choose for cost-sensitive industrial designs where leaded package compatibility and higher single-pulse margin outweigh size constraints. |
Compared with BZW04-15B-E3/54, SMBJ15CA offers superior board density but lacks through-hole mechanical robustness, while P6KE15CA provides higher single-event energy handling at the expense of larger footprint and slightly different thermal derating behavior - all three share identical VWM/VBR thresholds and bidirectional functionality.

FAQ
What is the polarity configuration of BZW04-15B-E3/54?
BZW04-15B-E3/54 is a bidirectional TVS diode with symmetrical anode/cathode terminals - no color band or marking is present, and either lead may connect to either side of the protected line. This enables straightforward implementation on AC-coupled or floating differential signals without orientation checks during assembly.
Does BZW04-15B-E3/54 meet automotive qualification standards?
Yes, BZW04-15B-E3/54 is AEC-Q101 qualified per Vishay documentation (Document Number 88316, Revision 16-Sep-2021). The "HE3" suffix denotes AEC-Q101 qualification, but the E3/54 variant - while RoHS-compliant and built on the same qualified die - carries commercial-grade screening. For full AEC-Q101 compliance, specify BZW04-15B-HE3/54.
What is the maximum clamping voltage of BZW04-15B-E3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-15B-E3/54 is 25.2 V measured at 16 A peak pulse current with a 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events.
Can BZW04-15B-E3/54 be used in place of a unidirectional TVS like BZW04-15-E3/54?
No - BZW04-15B-E3/54 is strictly bidirectional and must not replace unidirectional variants in DC-biased circuits requiring cathode-to-rail connection. Unidirectional types exhibit forward conduction below VBR; using BZW04-15B-E3/54 in such roles risks unintended conduction and system malfunction.
What packaging format is supplied for BZW04-15B-E3/54?
BZW04-15B-E3/54 is supplied in 13" diameter paper tape and reel packaging (package code "54"), with 550 units per reel. Lead finish is matte tin, compliant with J-STD-002 and JESD22-B102, and qualified to JESD201 Class 1A for whisker resistance.
