Product details
Overview
BZW04-110-E3/54 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 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 - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04-110-E3/54 datasheet, BZW04-110-E3/54 pinout, BZW04-110-E3/54 application, or BZW04-110-E3/54 equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified transient suppressor for bidirectional AC-coupled lines, DC bus rails, and low-capacitance analog front-ends where fast response (<1 ns), 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, delivering identical clamping behavior during positive and negative transients. Its glass-passivated junction ensures stable leakage and low incremental surge resistance, while the DO-41 package supports manual and automated through-hole assembly with J-STD-002 solderability.
The device sustains 400 W peak pulse power under 10/1000 μs waveform at TA = 25 °C and derates linearly above 25 °C per Fig. 2, with maximum junction temperature of 175 °C and storage range from –55 °C to +175 °C. It meets UL 94 V-0 flammability and JESD201 Class 1A whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 111 V - Maximum continuous reverse operating voltage before conduction begins; defines safe working margin for 100 V nominal DC or AC RMS lines. |
| VBR (min/max) | 124 V / 137 V at 1 mA - Verified breakdown threshold range ensuring consistent turn-on across production lots and temperature. |
| VC @ IPPM | 179 V at 2.2 A - Clamped voltage during 10/1000 μs surge; limits downstream IC stress to <180 V under worst-case 400 W transient. |
| IPPM | 2.2 A - Peak pulse current capability under standard 10/1000 μs waveform; enables protection against IEC 61000-4-5 Level 3 surges. |
| PPPM | 400 W - Peak pulse power handling capacity; supports repetitive surge events at 0.01 % duty cycle without thermal runaway. |
| TJ max | 175 °C - Maximum junction temperature; allows operation in under-hood automotive or high-ambient industrial environments. |
| Leakage @ VWM | <1 μA - Ultra-low reverse leakage preserves signal integrity in high-impedance sensor bias networks and precision references. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; no polarity marking for bidirectional configuration - both terminals are functionally identical and interchangeable in circuit layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals conduct identically during positive or negative overvoltage events; no cathode band marking required. |
| Lead 1 / Lead 2 | PCB interconnect interface | Matte tin-plated, solderable per J-STD-002; supports wave/solder dip up to 275 °C for 10 s. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance and <1 μA leakage at VWM, critical for long-term reliability in harsh environments. |
| 400 W peak pulse power (10/1000 μs) | Withstands repeated lightning-induced surges on industrial fieldbus lines without degradation or parametric shift. |
| AEC-Q101 qualified (E3/54 variant) | Validated for automotive applications including body control modules and sensor hubs requiring zero-failure reliability. |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed enclosures - mandatory for industrial safety-certified equipment. |
| Low temperature coefficient (0.107 %/°C) | Minimizes VBR drift across –55 °C to +175 °C, enabling stable clamping in wide-temperature automotive deployments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | DO-214AA (SMB) package; 110 V VWM, 122–135 V VBR, 187 V VC @ 2.1 A; 600 W PPPM. | Surface-mount only; higher clamping voltage and larger footprint; better suited for PCB space-constrained designs with higher surge budgets. | Select SMBJ110CA when SMT assembly is required and board layout cannot accommodate axial DO-41 leads. |
| P6KE110CA | DO-15 package; same VWM/VBR specs but lower PPPM (600 W), higher VC (193 V @ 2.1 A); not AEC-Q101 qualified. | General-purpose industrial use only; lacks automotive qualification and tighter leakage spec (<5 μA vs. <1 μA). | Choose P6KE110CA for cost-sensitive non-automotive applications where AEC-Q101 and ultra-low leakage are not mandated. |
Compared with SMBJ110CA and P6KE110CA, BZW04-110-E3/54 offers superior leakage performance (<1 μA), AEC-Q101 qualification, and axial through-hole compatibility - making it the preferred choice for automotive-grade, high-reliability, and legacy through-hole production environments.
