Product details
Overview
BZW04-10HE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal and power lines. It features 10.2 V stand-off voltage (VWM), 11.4–12.6 V breakdown voltage (VBR) at 1 mA, 16.7 V maximum clamping voltage (VC) at 24 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and microcontroller I/O in automotive and industrial control systems.
For engineers reviewing the BZW04-10HE3/54 datasheet, BZW04-10HE3/54 pinout, BZW04-10HE3/54 application, or BZW04-10HE3/54 equivalent, this device serves as an AEC-Q101 qualified, RoHS-compliant transient suppressor for bidirectional line protection where low clamping voltage, fast response, and high surge robustness are required.
Technical Context
The BZW04-10HE3/54 operates as a bidirectional avalanche diode with symmetrical clamping behavior in both polarities. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, enabling consistent voltage limiting during repetitive 10/1000 μs transients up to 400 W.
It exhibits a temperature coefficient of VBR at 0.078 %/°C and supports operation from –55 °C to +175 °C junction temperature. With 1.0 μA max reverse leakage at 10.2 V and 16.7 V clamping at 24 A, it delivers precise overvoltage protection without compromising signal integrity in low-power analog or digital interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.2 V - maximum continuous reverse working voltage before conduction begins; defines safe operating margin for 12 V nominal systems. |
| VBR min/max | 11.4 V / 12.6 V at 1 mA - tight breakdown tolerance ensures predictable turn-on across production lots and temperature. |
| VC @ IPPM | 16.7 V at 24 A - clamping voltage under 10/1000 μs surge; limits downstream IC stress to safe levels during ESD or load dump events. |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform; supports automotive-level ISO 7637-2 and IEC 61000-4-5 surge immunity. |
| ID @ VWM | 1.0 μA - ultra-low reverse leakage preserves battery life and signal accuracy in always-on sensor circuits. |
| TJ max | +175 °C - extended junction temperature rating enables use in under-hood automotive and high-ambient industrial environments. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per AEC standard. |

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 ESD and inductive kickback in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector or IC pad to shunt transients before they reach sensitive input stages. Use Value: 16.7 V clamping voltage prevents latch-up or damage to 5 V or 3.3 V interface ICs while maintaining signal fidelity during normal operation. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC field wiring, positioned upstream of optocoupler or Schmitt trigger input conditioning. Use Value: 400 W surge rating handles repetitive 100 V/500 ms transients per IEC 61000-4-4, extending system uptime in factory automation environments. |
| Consumer Power Adapter Protection | Telecom Line Interface Protection |
Use Scenario: Secondary-side transient suppression on 12 V output rails of AC/DC adapters for smart home hubs and set-top boxes. IC Role / Device Role / Timing Role: Standoff-clamp TVS placed between regulator output and downstream USB or Ethernet PHY power domains. Use Value: 1.0 μA leakage at 10.2 V minimizes quiescent current loss, critical for Energy Star and EU CoC Tier 2 compliance. |
Use Scenario: Overvoltage protection on telephone line interface circuits in VoIP gateways and PBX systems subject to lightning-induced surges. IC Role / Device Role / Timing Role: First-line defense on tip/ring lines before hybrid transformers and SLIC devices. Use Value: Symmetrical bidirectional clamping ensures equal protection against positive and negative surges without polarity-sensitive 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 |
|---|---|---|---|
| SMBJ10CA | DO-214AA package; 10 V VWM, 17.0 V VC @ 23.3 A; same 400 W PPPM but higher clamping voltage. | Surface-mount footprint requires PCB redesign; better suited for space-constrained consumer designs. | Select SMBJ10CA when board area is limited and reflow compatibility is preferred over through-hole assembly. |
| P6KE10CA | DO-15 package; 10 V VWM, 17.0 V VC @ 23.3 A; identical electrical specs but lower thermal mass and non-AEC-Q101 rated. | Lacks automotive qualification; suitable for commercial/industrial use where AEC-Q101 is not mandated. | Choose P6KE10CA for cost-sensitive industrial controls where AEC-Q101 is unnecessary and DO-15 mechanical fit is acceptable. |
Compared with BZW04-10HE3/54, SMBJ10CA offers SMT compatibility at the expense of through-hole serviceability, while P6KE10CA provides identical protection performance without automotive qualification - making BZW04-10HE3/54 the optimal choice for AEC-Q101–mandated automotive and high-reliability industrial deployments.

FAQ
What is the polarity configuration of BZW04-10HE3/54?
BZW04-10HE3/54 is a bidirectional TVS diode with symmetrical electrical characteristics in both directions. It has no polarity marking on the DO-41 package, confirming its bidirectional functionality - unlike unidirectional variants that feature a cathode band. This allows flexible placement on PCBs without orientation constraints, simplifying layout for differential or AC-coupled signal lines.
Is BZW04-10HE3/54 qualified for automotive applications?
Yes, BZW04-10HE3/54 is AEC-Q101 qualified, as confirmed by the "HE3" suffix and explicit note in the Vishay datasheet (Document Number: 88316, Revision: 16-Sep-2021). This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and surge endurance - validating its suitability for under-hood and chassis-mounted automotive electronics such as body control modules and sensor front-ends.
What is the maximum clamping voltage of BZW04-10HE3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-10HE3/54 is 16.7 V at 24 A peak pulse current, measured with a 10/1000 μs waveform. This value is specified in the Electrical Characteristics table for the BZW04-10B variant (bidirectional version), and the HE3/54 suffix denotes the same electrical performance in AEC-Q101 qualified packaging - ensuring predictable overvoltage limiting during real-world transients like load dump or ESD.
Does BZW04-10HE3/54 require heatsinking in normal operation?
No, BZW04-10HE3/54 does not require external heatsinking during transient suppression events due to its 400 W peak pulse power rating and short-duration energy absorption (10/1000 μs). Its 1.5 W steady-state power dissipation (PD) is only relevant for continuous DC stress - which is outside its intended use case. Thermal design focuses on lead termination and PCB copper area for surge current conduction, not heatsink attachment.
How does the "HE3/54" suffix in BZW04-10HE3/54 affect its specifications?
The "HE3" suffix indicates RoHS-compliance and AEC-Q101 qualification, while "/54" specifies the packaging format: 13-inch paper tape and reel with 550 units per reel. These suffixes do not alter electrical parameters - all performance values (VWM, VBR, VC, PPPM) match those of the base BZW04-10B bidirectional variant. The HE3/54 designation confirms manufacturing traceability, whisker testing (JESD201 Class 2), and automotive-grade reliability assurance for BZW04-10HE3/54.
