Product details
Overview
BZW04-14-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 13.6 V standoff voltage (VWM), 15.2–16.8 V breakdown voltage (VBR) at 1 mA, and clamps up to 22.5 V at 17.8 A peak pulse current - suitable for protecting MOSFETs and signal lines in industrial power supplies.
For engineers reviewing the BZW04-14-E3/54 datasheet, BZW04-14-E3/54 pinout, BZW04-14-E3/54 application, or BZW04-14-E3/54 equivalent, this device offers verified 400 W peak pulse power handling with 10/1000 μs waveform, AEC-Q101 qualification (E3 suffix denotes RoHS-compliant commercial grade), and low incremental surge resistance for robust overvoltage protection in DC power rails and sensor interfaces.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with DC supply paths or parallel to signal lines. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the unidirectional polarity enables integration into polarized circuits without reverse conduction concerns.
The device complies with ANSI/IEEE C62.35 surge standards and supports repetitive surge events at ≤0.01% duty cycle. Thermal derating follows a defined curve up to 175 °C maximum junction temperature, and its 1.5 W steady-state power dissipation allows reliable operation on PCB traces without heatsinking under normal bias conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.6 V - Maximum continuous reverse operating voltage before clamping begins; sets safe DC rail margin for 12 V systems. |
| VBR min/max | 15.2 V / 16.8 V at 1 mA - Confirmed breakdown range ensures consistent turn-on across production lots and temperature. |
| VC @ IPPM | 22.5 V at 17.8 A - Clamping voltage limits downstream IC stress during 400 W transient events. |
| PPPM | 400 W - Peak pulse power rating with 10/1000 μs waveform defines surge energy absorption capability. |
| IPPM | 17.8 A - Maximum non-repetitive surge current the device safely diverts without degradation. |
| TJ max | 175 °C - Maximum junction temperature enables operation in high-ambient industrial environments. |
| Leakage ID | 1.0 μA at VWM - Ultra-low reverse leakage minimizes standby power loss in battery-powered systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ14A | DO-214AA package; 14 V VWM, 23.2 V VC @ 17.2 A; same 400 W PPPM | Surface-mount footprint requires PCB redesign; higher VC increases downstream stress margin. | Select when automated SMT assembly is required and board space is constrained. |
| P6KE15A | DO-15 package; 15 V VWM, 23.5 V VC @ 17.0 A; 600 W PPPM but larger thermal mass | Higher power rating but slower response due to larger junction capacitance; not AEC-Q101 qualified. | Choose for cost-sensitive industrial designs where automotive qualification is unnecessary. |
Compared with SMBJ14A and P6KE15A, the BZW04-14-E3/54 delivers identical clamping performance in a through-hole DO-41 package with AEC-Q101 validation and lower leakage - making it optimal for legacy-compatible, high-reliability 12 V rail protection where manual or wave-solder assembly is used.

FAQ
What is the standoff voltage rating of the BZW04-14-E3/54?
The BZW04-14-E3/54 has a standoff voltage (VWM) of 13.6 V, meaning it remains non-conductive under continuous reverse bias up to this level. This value is selected to provide sufficient margin below typical 12 V nominal system rails while ensuring reliable clamping onset during overvoltage events. The BZW04-14-E3/54 maintains this rating across its full operating temperature range.
Is the BZW04-14-E3/54 suitable for automotive applications?
Yes - the BZW04-14-E3/54 carries AEC-Q101 qualification when ordered with the HE3 suffix (e.g., BZW04-14-HE3/54). The E3 suffix indicates RoHS-compliant commercial grade; for automotive use, confirm ordering the HE3 variant. The BZW04-14-E3/54 itself meets all electrical and thermal specs required for under-hood and body electronics, including 175 °C TJ max and robust surge endurance.
What does the "/54" in BZW04-14-E3/54 signify?
The "/54" denotes the preferred package code per Vishay's ordering system, indicating 13-inch diameter paper tape and reel packaging with a base quantity of 550 units. This format supports automated pick-and-place insertion and is standard for volume production. The BZW04-14-E3/54 is supplied in this configuration unless alternate packaging is specified.
How does the BZW04-14-E3/54 compare to bidirectional TVS diodes like BZW04-14B?
The BZW04-14-E3/54 is unidirectional, featuring a cathode band and conducting only in forward bias - ideal for polarized DC rails. In contrast, BZW04-14B is bidirectional with no polarity marking and symmetric clamping in both directions, suited for AC lines or differential data buses. The BZW04-14-E3/54 offers lower leakage and tighter VBR tolerance than its bidirectional counterpart, enhancing efficiency in single-supply systems.
What is the maximum clamping voltage of the BZW04-14-E3/54 during a surge event?
The BZW04-14-E3/54 clamps to a maximum of 22.5 V at its rated peak pulse current of 17.8 A (10/1000 μs waveform). This clamping voltage is guaranteed across production lots and temperature extremes, ensuring predictable protection margins for downstream components such as MOSFETs, gate drivers, and microcontrollers. The BZW04-14-E3/54 achieves this with low incremental surge resistance for minimal voltage overshoot.
