Product details
Overview
BZW04-154B-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 154 V standoff voltage (VWM), 171–189 V breakdown range (VBR at 1 mA), 246 V clamping voltage (VC) at 1.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the BZW04-154B-E3/54 datasheet, BZW04-154B-E3/54 pinout, BZW04-154B-E3/54 application, or BZW04-154B-E3/54 equivalent, this device delivers AEC-Q101-qualified transient immunity in DO-41 packaging with verified bidirectional clamping behavior, low leakage (<1.0 μA at VWM), and stable temperature coefficient (0.108 %/°C) across -55 °C to +175 °C operation.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, enabling single-device protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures consistent avalanche performance and low incremental surge resistance under repetitive 10/1000 μs transients at 0.01 % duty cycle.
The device complies with ANSI/IEEE C62.35 surge standards and supports high-reliability applications via AEC-Q101 qualification, UL 94 V-0 molded epoxy encapsulation, and matte tin-plated leads qualified per J-STD-002 and JESD22-B102 solderability standards.

Use Scenario: Protecting CAN/LIN bus transceivers and MEMS pressure/temperature sensors from load dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across differential signal pair or supply rail to shunt transient energy before it reaches sensitive analog front-end or transceiver IC. Use Value: Prevents latch-up or permanent damage to 12 V/24 V automotive-grade ICs by limiting voltage excursion to ≤246 V during 100 V/500 ms load dump events. |
Use Scenario: Safeguarding 4–20 mA current loop inputs and ±10 V analog inputs in programmable logic controllers exposed to field wiring surges. IC Role / Device Role / Timing Role: Standoff-mode protector mounted at connector entry point to absorb induced lightning-induced transients (IEC 61000-4-5) before reaching precision ADC or op-amp stages. Use Value: Maintains measurement accuracy by holding input voltage within ±15 V common-mode range during 2 kV/1.2/50 μs surges, avoiding saturation or offset shift. |
| Telecom Line Interface Protection | Power Supply Rail Clamp |
Use Scenario: Shielding Ethernet PHYs, DSL line drivers, and POTS interface ICs from induced surges on outdoor copper lines. IC Role / Device Role / Timing Role: Primary-level TVS placed between transformer secondary and PHY IC to clamp common-mode surges before isolation barrier. Use Value: Enables compliance with GR-1089-CORE telecom surge immunity requirements by limiting peak voltage to 246 V at 1.6 A, reducing need for secondary protection stages. |
Use Scenario: Clamping 12 V or 24 V DC power rails feeding microcontrollers, motor drivers, or communication modules in factory automation systems. IC Role / Device Role / Timing Role: Fast-response shunt device connected between rail and ground to divert inductive switching spikes from relay coils or solenoids. Use Value: Extends system uptime by preventing brownouts or resets caused by >200 V transients - validated for 40 A IFSM surge tolerance in unidirectional variants (same family). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A | Unidirectional; 150 V VWM; 167 V VBR; 243 V VC @ 1.6 A; SMC package (surface-mount) | Requires polarity-aware layout; lacks AEC-Q101 qualification; lower mounting density than axial DO-41 for through-hole designs. | Select when board space is constrained and unidirectional protection suffices with automated SMT assembly. |
| P6KE150A | Unidirectional; 150 V VWM; 167 V VBR; 243 V VC @ 1.6 A; DO-15 package; 600 W PPPM | Higher pulse power but larger DO-15 footprint; no AEC-Q101 qualification; higher leakage (5 μA typical). | Choose for legacy through-hole designs needing higher surge margin where automotive qualification is not required. |
Compared with BZW04-154B-E3/54, SMBJ150A offers surface-mount compatibility at the cost of polarity sensitivity and missing automotive qualification, while P6KE150A provides greater pulse power in a larger axial package but lacks AEC-Q101 validation and exhibits higher leakage - making BZW04-154B-E3/54 the optimal choice for new automotive and high-reliability industrial designs requiring bidirectional, qualified, low-leakage protection in DO-41 form factor.

FAQ
What is the polarity configuration of BZW04-154B-E3/54?
BZW04-154B-E3/54 is a bidirectional TVS diode with symmetrical avalanche characteristics in both directions. It has no cathode marking and may be installed without orientation concern - unlike unidirectional variants such as BZW04-154-E3/54, which require correct anode/cathode alignment. This makes BZW04-154B-E3/54 ideal for AC-coupled or floating signal paths where polarity reversal is possible.
Is BZW04-154B-E3/54 qualified for automotive use?
Yes, BZW04-154B-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor modules. The qualification covers stress testing for temperature cycling, humidity bias, mechanical shock, and accelerated life - all performed on the exact BZW04-154B-E3/54 construction with E3 RoHS-compliant terminations and DO-41 packaging.
What is the maximum clamping voltage of BZW04-154B-E3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-154B-E3/54 is 246 V at a peak pulse current (IPPM) of 1.6 A with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage imposed on protected circuitry during standardized surge events - critical for ensuring downstream components remain within their absolute maximum ratings.
How does the temperature coefficient affect BZW04-154B-E3/54's protection threshold?
BZW04-154B-E3/54 has a maximum temperature coefficient of VBR of 0.108 %/°C, meaning its breakdown voltage increases by up to 0.16 V per 10 °C rise above 25 °C. This positive drift ensures the device maintains safe margin above VWM (154 V) across its full -55 °C to +175 °C operating range, preventing premature conduction at high temperatures while retaining effective clamping during transients.
What packaging and reel format is supplied for BZW04-154B-E3/54?
BZW04-154B-E3/54 is supplied in 13-inch diameter paper tape and reel format with a base quantity of 550 units per reel (package code "54"). The E3 suffix confirms RoHS-compliant matte tin plating, J-STD-002 solderability, and JESD201 Class 1A whisker resistance - ensuring compatibility with standard wave and reflow solder processes in high-volume manufacturing.
