Product details
Overview
BZW04P5V8-E3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in signal and power lines. It features a 5.8 V stand-off voltage (VWM), 10.5 V maximum clamping voltage (VC) at 38 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - ideal for safeguarding MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD in industrial and automotive electronics.
For engineers reviewing the BZW04P5V8-E3/54 datasheet, BZW04P5V8-E3/54 pinout, BZW04P5V8-E3/54 application, or BZW04P5V8-E3/54 equivalent, key selection criteria include its DO-41 (DO-204AL) package, bi-directional polarity, AEC-Q101 qualification, low clamping ratio (VC/VWM ≈ 1.81), and 1000 μA max reverse leakage at VWM - critical for low-power sensor interface and 5 V rail protection designs.
Technical Context
The BZW04P5V8-E3/54 operates as a bi-directional avalanche diode, leveraging glass-passivated junction technology to achieve fast response time (<1 ns) and low incremental surge resistance. Its breakdown voltage range (6.45–7.48 V at 10 mA) ensures reliable triggering above system operating voltage while maintaining tight tolerance.
Designed for repetitive transient suppression, it sustains 400 W peak pulse power under 0.01% duty cycle (10/1000 μs waveform) and derates linearly above 25 °C ambient per Fig. 2. Junction temperature range spans –55 °C to +175 °C, supporting operation in harsh environments including engine control units and industrial motor drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.8 V - maximum continuous reverse working voltage; defines safe operating ceiling before conduction begins. |
| VBR (min/max) | 6.45 V / 7.48 V at 10 mA - guaranteed avalanche initiation window; ensures consistent turn-on across production lots. |
| VC @ IPPM | 10.5 V at 38 A - clamping voltage during 10/1000 μs surge; limits downstream voltage stress to ≤10.5 V. |
| PPPM | 400 W - peak pulse power handling; supports high-energy transients like ISO 7637-2 Pulse 1/2a without failure. |
| ID @ VWM | 1000 μA - max reverse leakage at 5.8 V; low enough to avoid loading 5 V logic or sensor bias networks. |
| Package | DO-204AL (DO-41) - axial-leaded through-hole package; compatible with legacy PCB layouts and wave soldering. |
| Qualification | AEC-Q101 qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD. |

| Consumer Power Adapter Output | Telecom Line Interface Protection |
Use Scenario: Secondary-side overvoltage suppression on 5 V USB charging outputs in wall adapters subject to lightning-induced surges. IC Role / Device Role / Timing Role: Final-stage TVS on low-voltage output rail, placed after DC-DC converter and before USB port connector. Use Value: Absorbs 400 W pulses without degradation, maintaining output regulation and preventing damage to connected mobile devices. |
Use Scenario: Protecting Ethernet PHY or DSL line drivers from induced surges on outdoor telecom drop cables. IC Role / Device Role / Timing Role: Bi-directional transient suppressor on differential pair (e.g., TX+/TX−), referenced to local ground plane. Use Value: Symmetric clamping preserves signal balance and common-mode rejection while limiting differential overvoltage to <11 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A | Uni-directional; 5.0 V VWM; DO-214AA (SMB) surface-mount package; 600 W PPPM. | Requires polarity-aware layout; better suited for PCB space-constrained 5 V rail protection where board area is limited. | Select SMBJ5.0A only if SMT assembly is mandatory and uni-directional protection suffices for the circuit topology. |
| P6KE6.8A | Uni-directional; 6.8 V VWM; DO-15 package; 600 W PPPM; higher VC (10.5 V same, but higher VBR spread). | Larger DO-15 footprint; wider VBR tolerance (6.45–7.65 V) may reduce margin in precision 5 V systems. | Choose P6KE6.8A only for cost-sensitive industrial designs where AEC-Q101 is not required and DO-41 footprint compatibility is secondary. |
Compared with SMBJ5.0A and P6KE6.8A, the BZW04P5V8-E3/54 offers bi-directional symmetry in a legacy-compatible DO-41 package with AEC-Q101 validation - making it uniquely suitable for automotive and retrofit industrial applications requiring polarity-agnostic, through-hole surge protection at 5.8 V standoff.
