Product details
Overview
BZW04-154BHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of 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 - suitable for automotive sensor interface and industrial I/O line protection.
For engineers reviewing the BZW04-154BHE3/54 datasheet, BZW04-154BHE3/54 pinout, BZW04-154BHE3/54 application, or BZW04-154BHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-41 mechanical compatibility, low leakage (<1 µA at VWM), and thermal stability up to +175 °C junction temperature.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical bidirectional conduction - no polarity marking required. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance across repeated transients.
The BZW04-154BHE3/54 delivers consistent clamping performance under 10/1000 µs surge waveforms up to 400 W, with derating above 25 °C ambient per Fig. 2 and validated operation from –55 °C to +175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 154 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 171 V / 189 V at 1 mA - precise breakdown threshold defining turn-on tolerance |
| VC @ IPPM | 246 V at 1.6 A - clamped voltage during 10/1000 µs transient, limiting downstream stress |
| PPPM | 400 W - peak surge energy handling capacity without failure under standard waveform |
| ID @ VWM | <1 µA - ultra-low reverse leakage preserves signal integrity in high-impedance circuits |
| TJ max. | +175 °C - extended thermal range supports under-hood automotive and industrial environments |
| AEC-Q101 | Qualified - validated reliability for automotive electronics per stress test requirements |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; compliant with UL 94 V-0 flammability rating and J-STD-002 solderability standards. Bidirectional construction means no cathode band - terminals are non-polarized.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Identical bidirectional clamping behavior - either terminal serves as input or return |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR over lifetime and temperature, minimizing parameter drift in harsh environments |
| 400 W peak pulse power (10/1000 µs) | Withstands repetitive surges up to 0.01% duty cycle without degradation |
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a/5a) |
| DO-41 mechanical compatibility | Direct drop-in replacement for legacy TVS diodes in existing through-hole PCB layouts |
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 inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential or single-ended signal lines upstream of interface ICs. Use Value: Limits transient voltage to ≤246 V while maintaining <1 µA leakage - preserving signal fidelity and enabling reliable operation per ISO 16750-2. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers against ESD and field-wiring induced surges in factory automation systems. IC Role / Device Role / Timing Role: Primary front-end protection element on 24 V DC input channels, mounted before optocoupler or level-shifter stages. Use Value: Absorbs 400 W surges without latch-up or parametric shift - extends system uptime and reduces field failure rates in ungrounded industrial environments. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Shielding Ethernet PHYs and RS-485 transceivers from lightning-induced surges on outdoor telecom/data lines. IC Role / Device Role / Timing Role: Secondary protection stage after gas discharge tube (GDT), providing fast-response clamping for residual transients. Use Value: Clamps within nanoseconds to 246 V, complementing slower primary protectors - meets ITU-T K.20/21 immunity requirements. |
Use Scenario: Suppressing line-to-line and line-to-ground surges at AC-DC adapter input stages in smart home devices and audio equipment. IC Role / Device Role / Timing Role: Bidirectional shunt protector across bridge rectifier inputs or bulk capacitor terminals. Use Value: Withstands 10/1000 µs surges up to 400 W while maintaining RoHS-compliant, lead-free assembly compatibility. |
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-E3/52 | Unidirectional; 150 V VWM; SMB package (SMT); 600 W PPPM | Requires polarity-aware layout; not AEC-Q101 qualified; higher power but surface-mount only | Select when board space is constrained and unidirectional protection suffices |
| P6KE150A | Unidirectional; 150 V VWM; DO-15 package; 600 W PPPM; no AEC-Q101 qualification | Larger DO-15 footprint; lower thermal performance; limited automotive acceptance | Choose for cost-sensitive industrial designs where AEC-Q101 is not mandated |
Compared with BZW04-154BHE3/54, SMBJ150A-E3/52 offers higher surge rating but lacks bidirectionality and automotive qualification, while P6KE150A provides comparable clamping but requires larger PCB real estate and does not meet automotive reliability standards.

FAQ
What is the clamping voltage of BZW04-154BHE3/54 under a 10/1000 µs surge?
The BZW04-154BHE3/54 clamps to a maximum of 246 V when subjected to its rated peak pulse current of 1.6 A using the standardized 10/1000 µs waveform. This value is measured per Figure 1 and Table on page 2 of Vishay document 88316, and defines the upper voltage limit imposed on protected circuitry during surge events.
Is BZW04-154BHE3/54 suitable for automotive applications?
Yes, BZW04-154BHE3/54 is AEC-Q101 qualified (as confirmed in the "Note (1)" on page 4 of Vishay document 88316), making it suitable for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces where reliability under thermal and mechanical stress is critical.
Does BZW04-154BHE3/54 have polarity markings?
No - BZW04-154BHE3/54 is a bidirectional TVS diode, and per Vishay documentation, "no marking on bidirectional types." Its symmetrical construction allows installation in either orientation across protected lines without regard to anode/cathode assignment.
What is the maximum junction temperature rating for BZW04-154BHE3/54?
The BZW04-154BHE3/54 has a maximum junction temperature (TJ max.) of +175 °C, as specified in the "MAXIMUM RATINGS AND THERMAL CHARACTERISTICS" table on page 1 of Vishay document 88316. This enables operation in high-temperature under-hood or industrial control cabinet environments.
How does the HE3 suffix affect BZW04-154BHE3/54?
Per Vishay's ordering information on page 4, the HE3 suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance - distinguishing it from commercial-grade E3 variants and confirming suitability for automotive production use.
