Product details
Overview
BZW04-110B-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 111 V standoff voltage (VWM), 124–137 V breakdown range (VBR at 1 mA), 179 V maximum clamping voltage (VC) at 2.2 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and industrial control inputs against inductive switching surges.
For engineers reviewing the BZW04-110B-E3/54 datasheet, BZW04-110B-E3/54 pinout, BZW04-110B-E3/54 application, or BZW04-110B-E3/54 equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified bidirectional TVS for robust overvoltage protection in automotive body electronics, industrial PLC I/O modules, and telecom line interface circuits where low leakage (<1 μA at VWM) and stable temperature coefficient (0.107 %/°C) are critical.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical breakdown and clamping characteristics in forward and reverse directions. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the DO-41 package supports manual or automated through-hole assembly with JESD22-B106-compliant soldering (275 °C max, 10 s).
The device delivers 400 W peak pulse power handling per 10/1000 μs waveform at TA = 25 °C, derating linearly above 25 °C per Fig. 2, and maintains operation across -55 °C to +175 °C junction temperature range. Its 0.107 %/°C VBR temperature coefficient ensures predictable clamping behavior under thermal stress in engine bay or industrial ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 111 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (min/max) | 124 V / 137 V at 1 mA - Verified breakdown range ensures reliable turn-on during transient events without premature conduction. |
| VC @ IPPM | 179 V at 2.2 A - Clamping voltage limits downstream circuit stress during 10/1000 μs surge; enables protection of 150 V-rated components. |
| IPPM | 2.2 A - Peak pulse current capability derived from 400 W rating and VC; validates surge handling per IEC 61000-4-5 Level 3. |
| ID @ VWM | <1 μA - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance sensor paths. |
| TJ max. | +175 °C - High junction temperature rating supports use in under-hood automotive and industrial motor drive environments. |
| Package | DO-41 (DO-204AL) - Standard through-hole package with 0.205" body diameter and axial leads; compatible with legacy PCB layouts and wave soldering. |
Pinout & Package
DO-41 (DO-204AL) package: axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards. Bidirectional construction means no polarity marking - both terminals are functionally identical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Identical bidirectional clamping behavior - either terminal may connect to protected line or ground; no orientation dependency in layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | DO-214AA package (SMB), 110 V VWM, 179 V VC @ 2.2 A, same 400 W rating but surface-mount only. | Requires PCB redesign for SMT placement; lacks through-hole mechanical robustness for high-vibration environments. | Select when board space is constrained and wave-solder compatibility is not required. |
| P6KE110CA | DO-15 package, 110 V VWM, 187 V VC @ 2.1 A, 600 W rating but higher clamping voltage and larger footprint. | Higher VC reduces protection margin for 150 V-rated components; lower surge current density than BZW04 series. | Choose only if legacy DO-15 footprint reuse is mandatory and 8 V higher clamping is acceptable. |
Compared with SMBJ110CA and P6KE110CA, the BZW04-110B-E3/54 offers optimal balance of through-hole reliability, precise 179 V clamping, and AEC-Q101 qualification - making it preferred for automotive and industrial designs requiring proven mechanical durability and thermal stability.

FAQ
What is the polarity configuration of BZW04-110B-E3/54?
The BZW04-110B-E3/54 is a bidirectional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional variants (e.g., BZW04-110-E3/54), it has no cathode marking and functions identically regardless of lead orientation - ideal for AC-coupled or floating signal line protection where polarity is undefined.
Does BZW04-110B-E3/54 meet automotive reliability standards?
Yes, BZW04-110B-E3/54 carries the HE3 suffix variant for AEC-Q101 qualification, and the E3/54 part is RoHS-compliant with JESD201 Class 1A whisker resistance. While the base E3/54 part is commercial-grade, its construction, glass passivation, and 175 °C TJ max align with automotive under-hood thermal requirements when applied per Vishay's derating guidelines.
What is the maximum clamping voltage of BZW04-110B-E3/54 under surge conditions?
The BZW04-110B-E3/54 has a maximum clamping voltage (VC) of 179 V at 2.2 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream component voltage margining in protected circuits.
Can BZW04-110B-E3/54 be used in place of unidirectional TVS diodes?
No - BZW04-110B-E3/54 is strictly bidirectional and must not replace unidirectional types (e.g., BZW04-110-E3/54) in DC-biased circuits where forward conduction would cause short-circuit failure. Its symmetrical behavior suits AC lines, differential pairs, or floating rails, but not single-polarity power rail protection without additional blocking diodes.
What packaging format does BZW04-110B-E3/54 ship in?
BZW04-110B-E3/54 ships in 13" diameter paper tape and reel format (package code 54), with 550 units per reel. The axial DO-41 leads are matte tin-plated and qualified per J-STD-002 and JESD22-B102 for reliable solder wetting in both manual and automated through-hole assembly processes.
