Product details
Overview
BZW04-11B-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 11.1 V standoff voltage (VWM), 12.4–13.7 V breakdown range at 1 mA test current, and clamps to ≤18.2 V at 22.0 A peak pulse current under 10/1000 μs waveform - suitable for protecting I/O ports and sensor interfaces in industrial control systems.
For engineers reviewing the BZW04-11B-E3/54 datasheet, BZW04-11B-E3/54 pinout, BZW04-11B-E3/54 application, or BZW04-11B-E3/54 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance, AEC-Q101 qualification status, and direct replacement options for ESD and surge protection design-in.
Technical Context
This bidirectional TVS operates symmetrically in both polarities with identical VBR, VC, and IPPM characteristics. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing fast-rising transients from inductive switching or ESD events.
The device sustains 400 W peak pulse power (10/1000 μs), dissipates 1.5 W continuously at TL = 75 °C, and supports operation from −55 °C to +175 °C junction temperature - validated per AEC-Q101 for automotive-grade reliability without polarity marking on the DO-41 case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11.1 V - maximum continuous reverse working voltage before conduction begins; defines safe operating margin below breakdown. |
| VBR min/max | 12.4 V / 13.7 V at IT = 1 mA - ensures predictable turn-on threshold across production lot and temperature. |
| VC @ IPPM | ≤18.2 V at 22.0 A - clamping voltage limits stress on downstream ICs during 400 W transient events. |
| IPPM | 22.0 A (10/1000 μs) - peak surge current handling capacity directly tied to PCB trace robustness and layout parasitics. |
| PPPM | 400 W - standardized surge rating enabling direct comparison with IEC 61000-4-5 Level 3/4 compliance test margins. |
| TJ max | +175 °C - high junction temperature rating supports use in under-hood automotive or enclosed industrial enclosures. |
| AEC-Q101 | Qualified - confirms reliability for automotive electronics including body control modules and sensor nodes. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; no polarity marking for bidirectional operation; matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

IC Role / Device Role / Timing Role: Standoff-and-clamp protector on 12 V supply rail and low-voltage signal lines; operates identically in positive/negative polarity events. Use Value: Maintains system uptime by absorbing 400 W surges without degradation, meeting AEC-Q101 lifetime requirements for 15-year vehicle service life. |
| Telecom Line Card Surge Suppression | Consumer Appliance Motor Drive Feedback Protection |
Use Scenario: Shielding Ethernet PHY power rails and RS-485 differential pairs in outdoor telecom cabinets subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Primary front-end TVS on DC input and data lines; coordinated with secondary MOV/GDT stages for staged energy diversion. Use Value: Clamps induced common-mode transients to <18.2 V before they reach isolation barriers or level-shifting ICs, preserving signal integrity. |
Use Scenario: Securing hall-effect sensor outputs and microcontroller ADC inputs in washing machine motor control boards exposed to brush-commutator noise and relay bounce. IC Role / Device Role / Timing Role: Localized transient suppressor mounted adjacent to sensor connector, minimizing loop inductance for optimal high-frequency suppression. Use Value: Prevents false triggering or ADC offset drift caused by sub-100 ns spikes, ensuring accurate rotor position detection during high-torque cycles. |
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; 11 V VWM; 12.2–13.5 V VBR; 19.9 V VC @ 21.1 A; same 400 W PPPM. | Surface-mount footprint; lower profile; higher thermal resistance than DO-41 axial leads. | Select SMBJ11CA when board space is constrained and reflow assembly is preferred over through-hole. |
| P6KE11CA | DO-15 package; 11 V VWM; 12.2–13.5 V VBR; 19.0 V VC @ 21.1 A; 600 W PPPM rating. | Higher surge rating but larger DO-15 body; not AEC-Q101 qualified; commercial grade only. | Choose P6KE11CA for cost-sensitive industrial applications where AEC-Q101 is unnecessary and higher single-pulse margin is required. |
Compared with BZW04-11B-E3/54, SMBJ11CA offers SMT compatibility at the expense of axial mechanical robustness and slightly tighter VC, while P6KE11CA trades automotive qualification for higher peak power and legacy through-hole fit - all three share identical VWM and bidirectional functionality but differ in package reliability, thermal path, and qualification scope.

FAQ
What is the standoff voltage and breakdown range of the BZW04-11B-E3/54?
The BZW04-11B-E3/54 has a standoff voltage (VWM) of 11.1 V and a breakdown voltage range of 12.4 V to 13.7 V at 1 mA test current. This ensures reliable non-conduction during normal operation while triggering promptly during overvoltage events - a key parameter for designing robust protection margins in 12 V systems where BZW04-11B-E3/54 is commonly deployed.
Is the BZW04-11B-E3/54 suitable for automotive applications?
Yes, the BZW04-11B-E3/54 is AEC-Q101 qualified and rated for operation from −55 °C to +175 °C, making it suitable for automotive body electronics, sensor interfaces, and infotainment I/O protection. Its bidirectional symmetry and DO-41 mechanical robustness align with under-dash and engine bay environmental requirements - confirmed in the official Vishay documentation for BZW04-11B-E3/54.
What is the clamping voltage of the BZW04-11B-E3/54 at its rated peak pulse current?
The BZW04-11B-E3/54 clamps to a maximum of 18.2 V at its rated peak pulse current of 22.0 A (10/1000 μs waveform). This clamping voltage directly determines the maximum stress imposed on downstream components - a critical value used in selecting BZW04-11B-E3/54 for protecting 12 V logic interfaces and transceivers against ISO 7637-2 and IEC 61000-4-5 surges.
Does the BZW04-11B-E3/54 have polarity markings on the package?
No, the BZW04-11B-E3/54 is a bidirectional TVS diode and carries no polarity marking on its DO-41 package. Its symmetrical construction allows either lead to be connected to the protected line or ground - a design feature explicitly stated in the Vishay datasheet for BZW04-11B-E3/54 and confirmed across all "B" suffix variants in the family.
What is the peak pulse power rating and test condition for the BZW04-11B-E3/54?
The BZW04-11B-E3/54 is rated for 400 W peak pulse power using the standardized 10/1000 μs double-exponential waveform per IEC 61000-4-5. This rating applies at TA = 25 °C and is derated linearly above that temperature - a core specification defining the surge-handling capability of BZW04-11B-E3/54 in real-world transient suppression applications.
