Product details
Overview
BZW04-14HE3/54 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 13.6 V stand-off voltage (VWM), 15.2–16.8 V breakdown voltage (VBR) at 1 mA test current, 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 automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the BZW04-14HE3/54 datasheet, BZW04-14HE3/54 pinout, BZW04-14HE3/54 application, or BZW04-14HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, bidirectional polarity, low clamping ratio (VC/VBR ≈ 1.49), and compatibility with 13" tape-and-reel automated assembly.
Technical Context
This device operates as a voltage-clamping protector with symmetrical bidirectional conduction, enabling suppression of both positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 μA at VWM), while the DO-41 package supports lead-free soldering per J-STD-002 and JESD22-B102.
The BZW04-14HE3/54 delivers 400 W peak pulse power handling under 10/1000 μs waveform with 0.01% duty cycle, and exhibits a temperature coefficient of VBR at +0.086 %/°C - critical for thermal stability in automotive under-hood environments up to TJ = 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.6 V - maximum continuous reverse working voltage before clamping initiates |
| VBR min/max | 15.2 V / 16.8 V at 1 mA - defines reliable breakdown onset window for transient detection |
| VC @ IPPM | 22.5 V at 17.8 A - clamping voltage limiting downstream circuit stress during surge events |
| PPPM | 400 W - peak transient energy absorption capability with standard 10/1000 μs waveform |
| ID @ VWM | <1 μA - ultra-low leakage preserves signal integrity in high-impedance sensor lines |
| TJ max | +175 °C - enables operation in AEC-Q101-qualified automotive and industrial ambient conditions |
| Package | DO-41 (DO-204AL) - industry-standard axial-leaded package compatible with legacy through-hole and auto-insertion processes |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; no polarity marking for bidirectional configuration - terminals are functionally symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both ends serve identical bidirectional clamping roles; no cathode band or polarity identification required |
Key Features

| 400 W peak pulse power | Withstands ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Level 3 surges without degradation |
| Low clamping ratio (VC/VBR ≈ 1.49) | Minimizes voltage overshoot during clamping - critical for protecting 15 V-rated ICs and MOSFET gates |
| JESD201 Class 2 whisker resistance | HE3 suffix confirms robustness against tin whisker growth in high-reliability industrial applications |
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 signal line and ground, responding within <1 ns to suppress spikes exceeding 13.6 V. Use Value: Prevents latch-up or gate oxide damage in 12 V automotive systems by limiting transient voltage to ≤22.5 V at 17.8 A. |
Use Scenario: Safeguarding digital input channels of programmable logic controllers against ESD and relay-coil flyback in factory automation cabinets. IC Role / Device Role / Timing Role: Standoff-mode protector on 24 V DC input lines, conducting only during >13.6 V excursions with sub-nanosecond response. Use Value: Eliminates need for external series impedance or RC filtering while maintaining signal fidelity due to <1 μA leakage at 13.6 V. |
| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Shielding RS-485 transceiver pins from lightning-induced surges on outdoor telecom wiring. IC Role / Device Role / Timing Role: Primary-level TVS on differential pair, operating bidirectionally to clamp both common- and differential-mode transients. Use Value: Meets IEC 61000-4-5 4 kV surge immunity requirement with single-device solution and no polarity constraints. |
Use Scenario: Suppressing commutation spikes from brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Across-motor terminals or power supply rails, absorbing repetitive 400 W pulses from inductive kickback. Use Value: Enables use of lower-voltage-rated MOSFETs (e.g., 30 V) by clamping spikes to 22.5 V, reducing system BOM cost. |
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 | DO-214AA package, 14 V VWM, 23.2 V VC @ 17.2 A, same 400 W PPPM but higher junction capacitance (≈150 pF) | Surface-mount alternative requiring PCB layout change; less suitable for through-hole legacy designs | Select SMBJ14CA only when SMT assembly and space constraints outweigh through-hole compatibility needs. |
| P6KE15CA | DO-15 package, 15 V VWM, 24.4 V VC @ 16.4 A, 600 W PPPM but non-AEC-Q101 rated and higher VF | Higher power margin but lacks automotive qualification and has looser VBR tolerance (±10% vs. ±5% for BZW04-14HE3/54) | Choose P6KE15CA for cost-sensitive industrial applications where AEC-Q101 is not mandated and 600 W headroom is prioritized. |
Compared with SMBJ14CA and P6KE15CA, the BZW04-14HE3/54 uniquely combines AEC-Q101 qualification, DO-41 through-hole compatibility, tight ±5% VBR tolerance, and JESD201 Class 2 whisker resistance - making it the preferred choice for automotive and high-reliability industrial replacements where legacy board design must be preserved.

FAQ
What is the polarity configuration of BZW04-14HE3/54?
The BZW04-14HE3/54 is a bidirectional TVS diode with symmetrical terminal behavior - no cathode marking is present, and both leads function identically for clamping positive or negative transients. This eliminates orientation concerns during manual or automated placement and simplifies schematic symbol usage compared to unidirectional variants like BZW04-14E3/54.
Is BZW04-14HE3/54 qualified for automotive applications?
Yes, the HE3 suffix explicitly denotes AEC-Q101 qualification for BZW04-14HE3/54, confirming compliance with stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. This makes BZW04-14HE3/54 suitable for under-hood and cabin electronics where reliability across -55 °C to +175 °C junction temperature is mandatory.
What does the "/54" suffix indicate in BZW04-14HE3/54?
The "/54" suffix in BZW04-14HE3/54 specifies the preferred packaging format: 13-inch diameter paper tape and reel containing 550 units. This format is optimized for high-speed pick-and-place machinery and aligns with IPC-7351 standards for DO-41 components, ensuring consistent feeding and reduced assembly downtime in volume production of BZW04-14HE3/54.
How does the clamping performance of BZW04-14HE3/54 compare to its VBR rating?
BZW04-14HE3/54 clamps transients to 22.5 V at 17.8 A (10/1000 μs), yielding a clamping ratio (VC/VBR) of approximately 1.49 - calculated using the midpoint of its specified VBR range (15.2–16.8 V). This tight ratio ensures minimal overvoltage exposure to protected ICs, especially critical for 15 V-rated interface components where excess voltage could cause cumulative degradation.
Can BZW04-14HE3/54 replace older BZW04-14B parts in existing designs?
Yes, BZW04-14HE3/54 is a direct functional and mechanical replacement for BZW04-14B, retaining identical electrical specs (VWM = 13.6 V, VBR = 15.2–16.8 V, VC = 22.5 V), DO-41 package dimensions, and bidirectional operation. The HE3 suffix adds AEC-Q101 qualification and JESD201 Class 2 whisker resistance - enhancements that improve reliability without requiring PCB or schematic changes for BZW04-14HE3/54 integration.
