Product details
Overview
BZW04-154HE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 154 V standoff voltage (VWM), 171–189 V breakdown range (VBR at 1 mA), and clamps transients to ≤246 V at 1.6 A peak pulse current (IPPM) under 10/1000 µs waveform - ideal for protecting automotive sensor signal lines against load dump and ESD.
For engineers reviewing the BZW04-154HE3/54 datasheet, BZW04-154HE3/54 pinout, BZW04-154HE3/54 application, or BZW04-154HE3/54 equivalent, this AEC-Q101 qualified device delivers 400 W peak pulse power, low leakage (<1 µA at VWM), and stable temperature coefficient (0.108 %/°C), supporting reliable design-in for industrial and automotive power rail and interface protection.
Technical Context
This bidirectional TVS operates symmetrically in both polarities with identical VBR, IPPM, and VC specifications in forward and reverse directions. Its glass-passivated junction ensures fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of fast-rising transients such as EFT and lightning-induced surges.
The device is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient, with 1.5 W steady-state power dissipation on infinite heatsink at 75 °C lead temperature. It meets JESD201 class 2 whisker resistance and UL 94 V-0 flammability requirements per its molded DO-41 epoxy case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 154 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown |
| VBR (min/max) | 171 V / 189 V at 1 mA - precise breakdown threshold ensuring predictable turn-on during overvoltage events |
| VC @ IPPM | ≤246 V at 1.6 A - clamping voltage limits downstream component stress during 10/1000 µs surge |
| PPPM | 400 W - peak transient energy handling capability under standardized surge waveform |
| ID @ VWM | <1 µA - ultra-low leakage preserves signal integrity and minimizes standby power loss |
| TJ max. | 175 °C - high-temperature operation supports under-hood automotive and industrial environments |
| Temp. coeff. of VBR | 0.108 %/°C - stable voltage tolerance across temperature, critical for precision protection circuits |
Pinout & Package
DO-41 (DO-204AL) axial-leaded package with matte tin-plated leads; no polarity marking - consistent with bidirectional function. Case meets UL 94 V-0; solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Identical bidirectional clamping behavior - either lead serves as input or return; no orientation dependency in PCB layout |
Key Features

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; SMA package; 600 W PPPM; higher IPPM (3.3 A) | Requires polarity-aware layout; better suited for DC power rail protection where directionality is fixed | Select when higher surge rating and surface-mount assembly are prioritized over bidirectionality and through-hole mounting |
| 1.5KE150A | Unidirectional; 150 V VWM; DO-201 package; 1500 W PPPM; larger footprint and higher VC (243 V) | Designed for primary-level AC/DC input protection; less suitable for low-voltage signal line clamping | Choose for high-energy front-end protection stages where board space allows and lower clamping precision is acceptable |
Compared with SMBJ150A-E3/52 and 1.5KE150A, the BZW04-154HE3/54 offers verified bidirectional symmetry, AEC-Q101 qualification, and DO-41 through-hole compatibility - making it uniquely appropriate for automotive signal-line protection where polarity independence and automotive-grade reliability are mandatory.

FAQ
What is the polarity configuration of BZW04-154HE3/54?
The BZW04-154HE3/54 is a bidirectional TVS diode with symmetrical electrical characteristics in both directions. It has no cathode marking and functions identically regardless of terminal orientation - making it ideal for AC-coupled or differential signal lines where polarity cannot be guaranteed. This behavior is confirmed in the Vishay datasheet Document Number 88316, Section "BIDIRECTIONAL TYPES".
Is BZW04-154HE3/54 qualified for automotive use?
Yes, BZW04-154HE3/54 carries the HE3 suffix, which denotes AEC-Q101 qualification per Vishay's ordering nomenclature. It is tested for temperature cycling, humidity, mechanical shock, and surge endurance under automotive-grade conditions - validated for use in engine control units, body control modules, and ADAS sensor interfaces per the official Vishay datasheet revision 16-Sep-2021.
What is the clamping voltage of BZW04-154HE3/54 under surge conditions?
The BZW04-154HE3/54 clamps to a maximum of 246 V when subjected to its rated 1.6 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within their absolute maximum ratings.
How does the HE3 suffix differ from E3 in BZW04-154HE3/54?
The HE3 suffix in BZW04-154HE3/54 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD201 class 2 whisker resistance. In contrast, the E3 suffix (e.g., BZW04-154-E3/54) denotes RoHS compliance only, without automotive qualification or enhanced whisker testing - making HE3 mandatory for automotive and high-reliability industrial designs.
Can BZW04-154HE3/54 replace BZW04-150HE3/54 in an existing design?
Yes, BZW04-154HE3/54 can serve as a functional replacement for BZW04-150HE3/54, with a slightly higher 154 V standoff voltage versus 150 V - resulting in marginally improved noise immunity and reduced leakage. Both share identical DO-41 packaging, AEC-Q101 qualification, and 400 W surge rating; no PCB or schematic changes are required for drop-in substitution in most applications.
