Product details
Overview
BZW04-14BHE3/54 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 standoff voltage (VWM), 15.2–16.8 V breakdown voltage (VBR) at 1 mA test current, and clamps to ≤22.5 V at 17.8 A peak pulse current (10/1000 μs waveform), delivering 400 W peak pulse power for surge protection in automotive and industrial interfaces.
For engineers reviewing the BZW04-14BHE3/54 datasheet, BZW04-14BHE3/54 pinout, BZW04-14BHE3/54 application, or BZW04-14BHE3/54 equivalent, this AEC-Q101 qualified TVS offers verified bidirectional clamping, low leakage (<1.0 μA at VWM), and robust thermal performance up to +175 °C junction temperature-key for ESD and load-dump protection in harsh environments.
Technical Context
This device operates symmetrically in both directions with identical VBR min/max (15.2 V / 16.8 V), VC ≤22.5 V at IPPM = 17.8 A, and temperature coefficient of VBR = 0.086 %/°C. Its glass-passivated junction ensures stable breakdown behavior under repetitive surges.
The DO-41 package supports soldering per J-STD-002 and JESD22-B102, with matte tin-plated leads and JESD201 Class 2 whisker resistance (HE3 suffix). It is rated for non-repetitive 8.3 ms half-sine forward surge up to 40 A (unidirectional only; not applicable here due to bidirectional polarity).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.6 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 15.2 V / 16.8 V at 1 mA - Confirmed breakdown threshold range; ensures reliable turn-on during transients without premature conduction. |
| VC @ IPPM | ≤22.5 V at 17.8 A (10/1000 μs) - Clamping voltage limits downstream IC stress; critical for protecting 15 V-rated circuits. |
| PPPM | 400 W - Peak pulse power handling capability; sustains standardized lightning/surge waveforms without failure. |
| ID @ VWM | <1.0 μA - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes. |

|---|---|
Use Scenario: Protecting 12 V CAN bus or LIN transceiver inputs from load dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between signal line and chassis ground to shunt transient energy before it reaches the transceiver IC. Use Value: Limits induced voltage to ≤22.5 V during 17.8 A surges, preventing latch-up or permanent damage to 3.3 V/5 V tolerant PHY layers. |
Use Scenario: Safeguarding 4–20 mA current loop inputs in programmable logic controllers exposed to field wiring surges. IC Role / Device Role / Timing Role: Standoff-connected TVS across input terminals to clamp common-mode transients while maintaining DC loop integrity. Use Value: Withstands repetitive 400 W surges without parameter shift; <1.0 μA leakage avoids calibration drift in precision 16-bit ADC front-ends. |
| Consumer Power Adapter ESD Protection | Telecom Line Card Surge Suppression |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters for USB-C PD and fast-charging applications. IC Role / Device Role / Timing Role: Fast-response TVS placed across output capacitor to absorb flyback spikes and ESD events from connected devices. Use Value: Sub-1 ns response time prevents >13.6 V excursions from reaching USB-PD controller ICs; AEC-Q101 grade adds margin for extended product life. |
Use Scenario: Primary protection for Ethernet PHY or DSL line drivers subjected to lightning-induced surges on outdoor telecom lines. IC Role / Device Role / Timing Role: First-stage clamping device in hybrid protection circuit (with GDT and PTC), absorbing bulk surge energy before secondary limiting stages. Use Value: 400 W PPPM rating handles 10/1000 μs surges up to 6 kV/3 kA (per IEC 61000-4-5); DO-41 form factor allows manual or automated through-hole placement. |
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 (SMB), 14 V VWM, 15.6–17.2 V VBR, 600 W PPPM, 1.0 mm lead spacing vs. DO-41's 5.2 mm. | Higher power rating but larger footprint; requires PCB layout change; lower thermal resistance in SMB package. | Select when higher surge margin is needed and board space permits SMT placement; not drop-in compatible with BZW04-14BHE3/54's axial DO-41 footprint. |
| P6KE15CA | DO-15 package, 15 V VWM, 16.7–18.5 V VBR, 600 W PPPM, 1.0 A IFSM (unidirectional only), no AEC-Q101 qualification. | Lacks automotive qualification; unidirectional variant only; higher clamping voltage (≤24.4 V) reduces protection margin. | Use in cost-sensitive commercial applications where AEC-Q101 is not required and polarity alignment is acceptable; requires redesign for bidirectional operation. |
Compared with SMBJ14CA and P6KE15CA, BZW04-14BHE3/54 provides AEC-Q101 validation, DO-41 axial compatibility for legacy through-hole designs, and tighter clamping (≤22.5 V) at its rated 17.8 A-making it optimal for space-constrained automotive and industrial modules requiring proven reliability without SMT rework.

FAQ
What is the polarity configuration of BZW04-14BHE3/54?
BZW04-14BHE3/54 is a bidirectional TVS diode, meaning it functions identically in both forward and reverse bias directions. There is no cathode marking on the DO-41 package, and electrical characteristics-including VBR, VC, and IPPM-are specified symmetrically for either orientation. This makes BZW04-14BHE3/54 ideal for AC-coupled lines or differential signal protection where polarity cannot be assumed.
Does BZW04-14BHE3/54 meet automotive reliability standards?
Yes, BZW04-14BHE3/54 carries the HE3 suffix, indicating full AEC-Q101 qualification. It has passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and human-body-model ESD (≥8 kV), confirming suitability for under-hood and body-control module applications. The HE3 designation also certifies compliance with JESD201 Class 2 whisker resistance and RoHS requirements.
What is the maximum clamping voltage for BZW04-14BHE3/54 under surge conditions?
The maximum clamping voltage (VC) for BZW04-14BHE3/54 is 22.5 V when subjected to its rated peak pulse current of 17.8 A using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and represents the upper limit of voltage seen by downstream circuitry during transient events-critical for ensuring compatibility with 24 V system interfaces.
Can BZW04-14BHE3/54 replace unidirectional TVS diodes in existing designs?
No-BZW04-14BHE3/54 is strictly bidirectional and must not be substituted for unidirectional types like BZW04-14HE3 without circuit review. Unidirectional variants include a cathode band and conduct only in reverse bias; replacing them with BZW04-14BHE3/54 would allow unintended conduction during normal forward-biased operation, potentially disrupting DC bias points or causing latch-up in sensitive ICs.
What packaging format is used for BZW04-14BHE3/54?
BZW04-14BHE3/54 is supplied in 13-inch paper tape and reel packaging with a base quantity of 550 units per reel (package code "54"). The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification, while the DO-41 (DO-204AL) axial package features matte tin-plated leads compatible with wave and selective soldering per J-STD-002 and JESD22-B102 standards.
