Product details
Overview
BZW04-110BHE3/54 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 111 V standoff voltage (VWM), 124–137 V breakdown range (VBR), 179 V clamping voltage at 2.2 A peak pulse current (IPPM), and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the BZW04-110BHE3/54 datasheet, BZW04-110BHE3/54 pinout, BZW04-110BHE3/54 application, or BZW04-110BHE3/54 equivalent, key selection considerations include its AEC-Q101 qualification, bidirectional polarity, DO-41 mechanical compatibility, and clamping performance under repetitive surge conditions per IEC 61000-4-5.
Technical Context
This device operates as a voltage-clamping protector with symmetrical bidirectional conduction - no cathode/anode distinction, enabling AC line and differential signal protection without polarity concerns. Its glass-passivated junction ensures stable VBR temperature coefficient (0.107 %/°C) and low leakage (<1.0 μA at VWM).
The 400 W peak pulse power rating is defined for non-repetitive 10/1000 μs transients at TA = 25 °C, derated linearly above 25 °C per Fig. 2, with maximum junction temperature limited to +175 °C and storage range from –55 °C to +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 111 V - maximum continuous reverse working voltage before clamping initiates; defines safe operating margin for 100 V nominal systems. |
| VBR min/max | 124 V / 137 V at 1 mA test current - verified breakdown threshold ensuring reliable turn-on during transients exceeding VWM. |
| VC @ IPPM | 179 V at 2.2 A - clamping voltage under standardized 10/1000 μs surge; limits downstream IC stress during ESD/EFT events. |
| PPPM | 400 W - peak transient energy absorption capability; supports IEC 61000-4-5 Level 3 (1 kV/2 kV) surge immunity design. |
| ID @ VWM | <1.0 μA - ultra-low reverse leakage at rated standoff, minimizing standby power loss in battery-powered sensor nodes. |
| TJ max | +175 °C - high-temperature junction rating enabling use in under-hood automotive and industrial motor control environments. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; matte tin-plated terminals compliant with J-STD-002 and JESD22-B102 solderability standards. Bidirectional construction means no polarity marking - both leads are electrically symmetric.

Use Scenario: Safeguarding RS-485/RS-232 communication lines and analog input channels in programmable logic controllers against EFT and lightning-induced surges. IC Role / Device Role / Timing Role: Bidirectional transient suppressor bridging differential pairs or single-ended lines to ground or rail. Use Value: Symmetric clamping behavior eliminates need for polarity-aware layout; DO-41 footprint allows retrofit into legacy industrial PCB designs. |
| Consumer Power Adapter Input | Telecom Line Card Protection |
Use Scenario: Secondary-side overvoltage suppression on DC outputs of wall adapters and USB PD chargers exposed to capacitor discharge events. IC Role / Device Role / Timing Role: Fast-response clamping device placed after rectification but before LDO regulators to limit transient propagation. Use Value: 179 V clamping voltage provides >20 V margin above 150 V DC output rails, preventing regulator overvoltage failure during surge tests. |
Use Scenario: Primary protection for Ethernet PHY interfaces and POTS line drivers in network edge equipment subjected to induced surges per GR-1089-CORE. IC Role / Device Role / Timing Role: First-stage TVS on line side of isolation transformers or common-mode chokes to absorb common-mode transients. Use Value: 400 W rating handles multi-kV surges; bidirectional operation matches AC-coupled telecom signaling without DC bias constraints. |
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; 110 V standoff; 187 V clamping at 2.1 A; same 400 W rating but higher thermal mass. | Surface-mount only; requires reflow-compatible PCB layout; better suited for high-volume automated assembly than through-hole DO-41. | Select SMBJ110CA when board space is constrained and SMT process is established; BZW04-110BHE3/54 remains optimal for manual repair, prototyping, or legacy through-hole designs. |
| P6KE110CA | DO-15 package; 110 V standoff; 187 V clamping at 2.1 A; 600 W peak power but lower surge current endurance due to larger junction capacitance. | Higher peak power but slower response; less effective for fast ESD pulses; not AEC-Q101 qualified. | Choose P6KE110CA only for cost-sensitive non-automotive applications where AEC-Q101 compliance and low capacitance are not required. |
Compared with SMBJ110CA and P6KE110CA, BZW04-110BHE3/54 offers AEC-Q101 qualification, DO-41 through-hole compatibility, and tighter clamping consistency - making it the preferred choice for automotive and industrial field-replaceable modules where reliability and serviceability are critical.
