Product details
Overview
BZW04-11BHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of signal and power lines. It features a 11.1 V standoff voltage (VWM), 12.4–13.7 V breakdown voltage (VBR) at 1 mA, 18.2 V clamping voltage (VC) at 22 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04-11BHE3/54 datasheet, BZW04-11BHE3/54 pinout, BZW04-11BHE3/54 application, or BZW04-11BHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-41 mechanical compatibility, low leakage (<1 μA at VWM), and thermal stability up to +175 °C junction temperature.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical bidirectional conduction - no polarity marking required. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 μs transients at 0.01% duty cycle.
Designed for high-reliability environments, BZW04-11BHE3/54 meets AEC-Q101 stress testing requirements and supports soldering per JESD 22-B106 (275 °C, 10 s). The DO-41 package provides UL 94 V-0 flammability compliance and matte tin-plated leads qualified to J-STD-002 and JESD22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11.1 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 12.4 V / 13.7 V at 1 mA - precise breakdown threshold ensures predictable turn-on during transients |
| VC @ IPPM | 18.2 V at 22 A - low clamping voltage limits downstream IC stress during 400 W surge events |
| PPPM | 400 W - peak pulse power handling with standard 10/1000 μs waveform defines surge immunity level |
| ID @ VWM | <1 μA - minimal leakage preserves signal integrity and power efficiency in standby |
| TJ max | +175 °C - extended junction temperature range supports under-hood and industrial ambient conditions |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |

|---|---|
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 differential signal pair or supply rail to shunt transient energy before reaching sensitive ASICs. Use Value: Maintains signal fidelity during 400 W surges while limiting clamped voltage to 18.2 V - below absolute maximum ratings of 24 V automotive interface ICs. | Use Scenario: Safeguarding digital input modules in programmable logic controllers against field-wiring induced surges from solenoid coils and motor contactors. IC Role / Device Role / Timing Role: Primary overvoltage suppression element on 24 V DC input channels, mounted directly at connector entry point. Use Value: Withstands repetitive 10/1000 μs transients at 0.01% duty cycle - enabling reliable operation in factory automation with frequent actuator switching. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Shielding Ethernet PHY front-end circuitry and PoE injectors from lightning-induced surges on unshielded twisted-pair cabling. IC Role / Device Role / Timing Role: Secondary-level TVS placed after gas discharge tube (GDT) in hybrid protection scheme for telecom infrastructure equipment. Use Value: Fast clamping action (<1 ns) complements slower GDT response, reducing let-through voltage to protect 100BASE-TX magnetics and PHY ICs. | Use Scenario: Input-stage surge protection for AC-DC adapters used in smart home hubs and set-top boxes subjected to mains-borne transients. IC Role / Device Role / Timing Role: Standoff-rated suppressor across primary-side rectifier output to absorb line-to-line and line-to-ground spikes. Use Value: 11.1 V VWM allows compatibility with 12 V nominal adapter outputs while providing margin against ripple-induced false triggering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | DO-214AA package (SMB), 11.1 V VWM, 12.2–13.5 V VBR, 19.9 V VC @ 21.1 A - slightly lower clamping but higher thermal mass | Surface-mount layout; better PCB space efficiency but requires reflow-compatible design | Select when automated SMT assembly and board density are priorities over through-hole serviceability |
| P6KE11CA | DO-15 package, 11.1 V VWM, 12.2–13.5 V VBR, 19.0 V VC @ 21.1 A - identical electrical specs but non-AEC-Q101 rated | Commercial/industrial use only; not validated for automotive temperature cycling or humidity testing | Choose for cost-sensitive non-automotive applications where AEC-Q101 is not mandated |
Compared with SMBJ11CA and P6KE11CA, BZW04-11BHE3/54 offers AEC-Q101 qualification and DO-41 through-hole mounting - making it optimal for automotive replacement service, prototyping, and industrial control panels requiring mechanical robustness and high-temperature reliability.

FAQ
What is the clamping voltage of BZW04-11BHE3/54 under a 10/1000 μs surge?
The BZW04-11BHE3/54 has a maximum clamping voltage (VC) of 18.2 V at 22 A peak pulse current with a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and ensures downstream circuitry remains within safe operating limits during standardized surge events. The clamping performance is guaranteed across the full operating temperature range from –55 °C to +175 °C.
Is BZW04-11BHE3/54 suitable for automotive applications?
Yes, BZW04-11BHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its qualification covers temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD) testing per automotive reliability standards. The HE3 suffix denotes AEC-Q101 compliance, and the device is commonly deployed in engine control units, body control modules, and ADAS sensor interfaces.
Does BZW04-11BHE3/54 have polarity markings?
No, BZW04-11BHE3/54 is a bidirectional TVS diode and carries no polarity marking - the DO-41 package has identical terminals with symmetrical electrical characteristics in both directions. This eliminates orientation errors during manual or automated assembly and simplifies layout for differential or AC-coupled protection schemes.
What is the maximum junction temperature rating for BZW04-11BHE3/54?
The BZW04-11BHE3/54 has a maximum junction temperature (TJ max) of +175 °C, enabling operation in high-ambient environments such as under-hood automotive locations or sealed industrial enclosures. This rating is supported by its glass-passivated chip construction and UL 94 V-0 epoxy molding compound, which maintains structural integrity and insulation performance at elevated temperatures.
How does the HE3 suffix differ from E3 in BZW04-11BHE3/54?
The HE3 suffix in BZW04-11BHE3/54 indicates RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. In contrast, the E3 suffix denotes RoHS compliance and JESD201 Class 1A whisker testing - suitable for commercial-grade applications only. The HE3 variant is mandatory for automotive and high-reliability industrial deployments.
