Product details
Overview
BZW04-5V8-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 and power lines. It features 5.8 V standoff voltage (VWM), 6.45–7.14 V breakdown voltage (VBR) at 10 mA test current, 10.5 V clamping voltage (VC) at 38 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - suitable for protecting MOSFET gates and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the BZW04-5V8-E3/54 datasheet, BZW04-5V8-E3/54 pinout, BZW04-5V8-E3/54 application, or BZW04-5V8-E3/54 equivalent, key selection considerations include its bidirectional polarity, 1000 μA max reverse leakage at VWM, -55 °C to +175 °C operating junction temperature, AEC-Q101 qualification, and DO-41 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
This device operates as a voltage-clamping protection element that conducts only when transient voltage exceeds its breakdown threshold in either polarity. Its glass-passivated junction ensures stable VBR tolerance and low incremental surge resistance, enabling consistent clamping performance across repetitive 10/1000 μs surges at 0.01% duty cycle.
The BZW04-5V8-E3/54 exhibits a temperature coefficient of VBR at +0.057 %/°C and maintains 10.5 V clamping voltage up to 38 A peak pulse current - critical for limiting induced overvoltage stress on downstream ICs during inductive load switching events in 12 V automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.8 V - maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (min/max) | 6.45 V / 7.14 V at 10 mA - precise breakdown window ensures predictable turn-on timing during transients. |
| VC @ IPPM | 10.5 V at 38 A - clamping voltage limits downstream component stress during worst-case 400 W surge events. |
| PPPM | 400 W - peak pulse power handling with 10/1000 μs waveform supports robust protection against IEC 61000-4-5 Level 3 surges. |
| ID @ VWM | 1000 μA - low leakage preserves signal integrity and minimizes standby power loss in always-on circuits. |
| TJ range | -55 °C to +175 °C - wide junction temperature range enables deployment in under-hood automotive and industrial 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; no polarity marking - bidirectional configuration confirmed by "B" suffix in family designation and absence of cathode band per datasheet note.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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-E3/52 | Unidirectional; 5.0 V VWM; SMC (DO-214AB) surface-mount package; 600 W PPPM rating. | Requires polarity-aware layout; suited for space-constrained PCBs where reflow assembly is preferred over through-hole. | Select when higher surge rating and SMT compatibility outweigh need for bidirectional symmetry and through-hole mounting. |
| P6KE6.8A | Unidirectional; 6.8 V VWM; DO-15 package; 600 W PPPM; no AEC-Q101 qualification. | Lacks automotive qualification; higher VWM reduces margin for 5 V rail protection; larger DO-15 footprint than DO-41. | Choose for cost-sensitive industrial applications where AEC-Q101 is not mandated and 6.8 V standoff is acceptable. |
Compared with SMBJ5.0A-E3/52 and P6KE6.8A, the BZW04-5V8-E3/54 provides verified bidirectional clamping, tighter VBR tolerance (±5%), DO-41 through-hole compatibility for high-reliability mechanical retention, and AEC-Q101 validation - making it optimal for automotive and mission-critical industrial designs requiring polarity-agnostic surge immunity.

FAQ
What is the polarity configuration of the BZW04-5V8-E3/54?
The BZW04-5V8-E3/54 is a bidirectional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional variants, it has no cathode marking and functions identically regardless of voltage polarity - essential for protecting AC-coupled or differential signal lines where transient direction is unpredictable. This behavior is confirmed by its inclusion in the BZW04-5V8B family listing and absence of color band per datasheet notes.
Is the BZW04-5V8-E3/54 qualified for automotive use?
Yes, the BZW04-5V8-E3/54 is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet revision 16-Sep-2021 (Document Number: 88316). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, validating its suitability for under-hood and cabin electronics such as body control modules and sensor interfaces where reliability under thermal and electrical stress is critical. The "E3" suffix denotes RoHS-compliant commercial grade, while "HE3" indicates AEC-Q101 grade - both share identical electrical specs.
What does the "E3/54" suffix mean in BZW04-5V8-E3/54?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker resistance. The "/54" denotes the preferred packaging code: 13-inch diameter paper tape and reel containing 550 units. This format enables automated pick-and-place insertion for through-hole assembly lines and ensures traceable, moisture-barrier compliant handling per Vishay's ordering information table.
How does the clamping performance of BZW04-5V8-E3/54 compare to its VWM and VBR ratings?
The BZW04-5V8-E3/54 clamps at 10.5 V when subjected to its rated 38 A peak pulse current (IPPM), which is 81% above its 5.8 V standoff voltage (VWM) and 46–64% above its 6.45–7.14 V breakdown range (VBR). This controlled voltage overshoot ensures protected circuits remain within safe operating limits during transients while maintaining low leakage (<1000 μA) below VWM - a balance critical for preserving signal fidelity in low-voltage sensor interfaces without compromising surge immunity.
Can BZW04-5V8-E3/54 replace older DO-41 TVS diodes like P4KE6.8A?
The BZW04-5V8-E3/54 can functionally replace P4KE6.8A in many applications due to matching DO-41 package, comparable VWM (5.8 V vs. 6.8 V), and similar clamping voltage (10.5 V vs. ~10.5 V), but differences exist: BZW04-5V8-E3/54 is bidirectional and AEC-Q101 qualified, whereas P4KE6.8A is unidirectional and lacks automotive qualification. Replacement requires verifying polarity requirements and confirming that the lower VWM provides sufficient margin for the target 5 V rail - especially under elevated temperature where VBR drift must be accounted for.
