Product details
Overview
BZW04-11HE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. 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 signal lines, industrial I/O ports, and telecom interface protection.
For engineers reviewing the BZW04-11HE3/54 datasheet, BZW04-11HE3/54 pinout, BZW04-11HE3/54 application, or BZW04-11HE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical dimensions, clamping performance under surge conditions, and direct alternatives for circuit-level ESD/transient hardening.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping transient voltages above ±12.4 V in either polarity without requiring external biasing. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the 10/1000 μs surge response supports repetitive transients up to 0.01% duty cycle.
Designed for AEC-Q101 qualification, BZW04-11HE3/54 sustains operation from –55 °C to +175 °C junction temperature and withstands solder dip at 275 °C for 10 s. Its 0.081 %/°C VBR temperature coefficient enables predictable clamping behavior across automotive thermal profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11.1 V - Maximum continuous reverse operating voltage before conduction begins; defines safe signal swing margin in protected line. |
| VBR (min/max) | 12.4 V / 13.7 V at 1 mA - Confirmed breakdown threshold range; ensures reliable turn-on during fast transients without premature leakage. |
| VC @ IPPM | 18.2 V at 22 A - Clamped voltage during 10/1000 μs surge; limits downstream IC stress to safe levels per IEC 61000-4-5 Level 4. |
| PPPM | 400 W - Peak pulse power handling capacity; supports high-energy lightning-induced surges in industrial fieldbus interfaces. |
| IPPM | 22 A - Peak pulse current capability; validates protection against 1 kV/500 Ω combination wave surges. |
| TJ max. | +175 °C - Maximum junction temperature; enables placement near heat-generating components in engine control units. |
| AEC-Q101 | Qualified - Certified for automotive-grade reliability including temperature cycling, HTRB, and surge endurance testing. |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, epoxy-molded case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards. HE3 suffix denotes AEC-Q101 qualification and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point in forward bias; cathode-defined polarity absent in bidirectional configuration | No polarity marking on device body - symmetrical conduction in both directions eliminates orientation dependency during PCB placement. |
| Cathode (unmarked end) | Current exit point in forward bias; identical terminal to anode in bidirectional operation | Both terminals function identically under reverse or forward surge events; simplifies layout and eliminates assembly error risk. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance (±5%) and <1.0 μA leakage at VWM, critical for low-power sensor front-ends. |
| 400 W peak pulse power (10/1000 μs) | Withstands repeated 1 kV/500 Ω surges per IEC 61000-4-5 without degradation - validated for industrial PLC analog input protection. |
| AEC-Q101 qualification | Guarantees reliability across automotive temperature cycles (-40 °C to +125 °C ambient), vibration, and humidity exposure. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns rise time), improving protection margin for 3.3 V/5 V logic interfaces. |
Applications
| Automotive Sensor Protection | Industrial Analog Input Protection |
|---|---|

| Telecom Interface Protection | Consumer Device USB/UART Protection |
|
Use Scenario: Shielding RS-485 transceivers and Ethernet PHY signal pairs from lightning-induced surges in outdoor base station equipment. IC Role / Device Role / Timing Role: First-line TVS on differential data lines, paired with common-mode chokes to suppress both differential and common-mode transients.

Use Scenario: Adding ESD and surge resilience to USB 2.0 D+/D− and UART TX/RX traces in smart home hubs and portable medical monitors. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor (CJ < 100 pF typical) placed adjacent to connector to minimize signal distortion. Use Value: 18.2 V clamping voltage prevents damage to 3.3 V USB transceivers while maintaining <1 ns response time for IEC 61000-4-2 ±8 kV contact discharge. |
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, 18.2 V VC @ 21.5 A, same PPPM = 400 W, but higher junction capacitance (~150 pF) | Preferred where board space allows surface-mount and higher capacitance is acceptable (e.g., DC power rails) | Select SMBJ11CA when footprint constraints favor SMD or when higher surge repetition rate is required (SMB thermal mass improves duty-cycle handling). |
| P6KE11CA | DO-15 package, 11.1 V VWM, 19.0 V VC @ 21.1 A, PPPM = 600 W, larger case size, non-AEC-Q101 | Suitable for non-automotive industrial power supply inputs needing higher single-pulse energy absorption | Choose P6KE11CA only for cost-sensitive commercial designs without automotive qualification requirements and where 19.0 V clamping is acceptable. |
Compared with BZW04-11HE3/54, SMBJ11CA offers SMD compatibility but sacrifices low-capacitance advantage, while P6KE11CA trades AEC-Q101 compliance and compact DO-41 form factor for higher single-pulse robustness - making BZW04-11HE3/54 optimal for space-constrained, automotive-grade signal-line protection.

FAQ
What is the polarity configuration of BZW04-11HE3/54?
BZW04-11HE3/54 is a bidirectional TVS diode with no polarity marking on the DO-41 package. It provides symmetrical clamping in both directions - ideal for protecting AC-coupled or differential signal lines where voltage transients may occur with either polarity. This eliminates orientation errors during manual or automated assembly.
Does BZW04-11HE3/54 meet automotive qualification standards?
Yes, BZW04-11HE3/54 carries the HE3 suffix, confirming full AEC-Q101 qualification. It has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and surge endurance - making it suitable for under-hood and chassis-mounted applications in passenger vehicles and commercial vehicles.
What is the maximum clamping voltage of BZW04-11HE3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-11HE3/54 is 18.2 V at 22 A peak pulse current with a 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures downstream 5 V or 3.3 V ICs remain within safe absolute maximum ratings during transient events.
Can BZW04-11HE3/54 be used in place of unidirectional TVS diodes?
No - BZW04-11HE3/54 is strictly bidirectional and must not replace unidirectional types (e.g., BZW04-11HE3 without 'B' suffix) in DC-biased circuits requiring forward conduction blocking. Its symmetrical IV curve provides no DC blocking function; use only where bidirectional surge suppression is explicitly required.
What packaging format is supplied for BZW04-11HE3/54?
BZW04-11HE3/54 is supplied in 13-inch paper tape and reel packaging (package code 54), with 550 units per reel. The HE3 suffix confirms RoHS compliance, AEC-Q101 qualification, and JESD201 Class 2 whisker resistance - ensuring long-term solder joint reliability in high-vibration environments.
