Product details
Overview
BZW04P14BHE3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 13.6 V stand-off voltage (VWM), 22.5 V maximum clamping voltage (VC) at 17.8 A peak pulse current, 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the BZW04P14BHE3/54 datasheet, BZW04P14BHE3/54 pinout, BZW04P14BHE3/54 application, or BZW04P14BHE3/54 equivalent, key selection criteria include its DO-204AL (DO-41) package, bi-directional polarity, low 0.086 %/°C VBR temperature coefficient, and suitability for protecting sensitive ICs and MOSFETs against inductive switching transients and ESD events.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 15.2 V and 17.6 V at 1 mA test current. Its clamping performance is defined at 17.8 A (10/1000 µs waveform), delivering 22.5 V maximum clamping voltage - critical for limiting stress on downstream components during surge events.
The device uses a glass-passivated chip junction and matte tin-plated leads compliant with J-STD-002 and JESD22-B102. Its AEC-Q101 qualification, 175 °C max junction temperature, and UL 94 V-0 molded epoxy case confirm suitability for harsh automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.6 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working margin below breakdown. |
| VBR (min/max) | 15.2 V / 17.6 V at 1 mA - Ensures reliable triggering across process and temperature variation; guarantees suppression onset within defined window. |
| VC @ IPPM | 22.5 V at 17.8 A - Clamping voltage under 400 W 10/1000 µs surge; directly limits voltage seen by protected circuitry. |

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting LIN bus transceivers and microcontroller I/O pins from load dump and alternator ripple in 12 V vehicle systems. IC Role / Device Role / Timing Role: Parallel-connected bi-directional TVS providing low-impedance shunt path during transients, clamping voltage to ≤22.5 V to prevent latch-up or gate oxide damage. Use Value: Enables compliance with ISO 7637-2 Pulse 5a (load dump) while maintaining signal integrity due to sub-1 ns response time and minimal capacitance. | Use Scenario: Safeguarding analog outputs and digital communication lines (e.g., RS-485, CAN FD stubs) in factory automation sensors exposed to motor switching noise. IC Role / Device Role / Timing Role: Standoff-mode protector placed across differential pairs or supply rails; absorbs repetitive 400 W surges without degradation. Use Value: Extends sensor lifetime in harsh EMI environments by suppressing >1 kV transients while maintaining <1 µA leakage at 13.6 V operating voltage. |
| Consumer Equipment Power Input | Telecom DC Power Feeds |
Use Scenario: Input-stage surge protection for AC/DC adapters and USB-C PD controllers subjected to lightning-induced surges on mains-derived DC rails. IC Role / Device Role / Timing Role: Primary-level TVS placed between input capacitor and upstream rectifier; clamps fast-rising transients before they reach regulation circuitry. Use Value: Prevents catastrophic failure of primary-side MOSFETs and controllers by limiting peak voltage to 22.5 V during 10/1000 µs events up to 400 W. | Use Scenario: Overvoltage protection on -48 V telecom power distribution boards where hot-swap events and relay bounce generate high-energy spikes. IC Role / Device Role / Timing Role: Bi-directional clamp across power rail and return; handles both positive and negative polarity surges inherent in shared-return architectures. Use Value: Maintains system uptime by surviving ≥1000 surges at rated IPPM, verified per AEC-Q101 endurance testing protocols. |
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 | Same DO-214AA package; 14 V VWM, 23.2 V VC @ 17.2 A; lower PPPM (600 W vs. 400 W), but higher IPPM rating. | Higher clamping voltage and larger footprint; less suitable for space-constrained PCBs requiring DO-41 form factor. | Select SMBJ14CA only when board layout allows SMC/SMB package and higher clamping voltage is acceptable. |
| P6KE15CA | DO-15 package; 15 V VWM, 24.4 V VC @ 16.3 A; 600 W PPPM; not AEC-Q101 qualified. | Larger body size and non-automotive qualification limit use in automotive ECUs or safety-critical modules. | Prefer P6KE15CA for cost-sensitive industrial applications where AEC-Q101 is not mandated and DO-15 mounting is feasible. |
Compared with SMBJ14CA and P6KE15CA, BZW04P14BHE3/54 offers the unique combination of DO-41 axial package, AEC-Q101 qualification, and precise 13.6 V standoff - making it optimal for legacy-compatible automotive harnesses and compact sensor modules where leaded through-hole mounting is required.

FAQ
What is the polarity configuration of BZW04P14BHE3/54?
BZW04P14BHE3/54 is a bi-directional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions. There is no cathode marking on the device body, and either lead may be connected to either side of the protected line - eliminating orientation concerns during assembly and simplifying PCB layout for differential or AC-coupled signals.
Does BZW04P14BHE3/54 meet automotive qualification standards?
Yes, BZW04P14BHE3/54 carries the HE3 suffix, indicating it is RoHS-compliant and AEC-Q101 qualified. This certification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST), confirming suitability for under-hood and chassis-mounted automotive electronics.
What is the maximum clamping voltage of BZW04P14BHE3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04P14BHE3/54 is 22.5 V, measured at 17.8 A peak pulse current using the standard 10/1000 µs waveform. This value represents the upper limit of voltage imposed on the protected circuit during a full-rated surge event, ensuring downstream ICs and MOSFETs remain within safe operating limits.
Can BZW04P14BHE3/54 be used in place of uni-directional TVS diodes?
No - BZW04P14BHE3/54 is strictly bi-directional and must not replace uni-directional TVS diodes in DC-biased circuits where reverse blocking is required. In such cases, a uni-directional variant like BZW04P14HE3/54 (with cathode band) would be appropriate; substituting BZW04P14BHE3/54 could result in unintended conduction during normal operation.
What is the junction temperature range for BZW04P14BHE3/54?
BZW04P14BHE3/54 is rated for an operating junction and storage temperature range of -55 °C to +175 °C. This wide range supports deployment in extreme environments such as engine control units, industrial motor drives, and outdoor telecom equipment, where ambient temperatures exceed 125 °C and thermal cycling is frequent.
