Product details
Overview
BZW04-5V8B-E3/73 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 stand-off voltage (VWM), 6.45–7.14 V breakdown voltage (VBR) at 10 mA, 400 W peak pulse power (10/1000 μs), and clamps to ≤10.5 V at 38 A peak pulse current. It is used in automotive sensor interfaces and industrial I/O protection where bidirectional surge immunity is required.
For engineers reviewing the BZW04-5V8B-E3/73 datasheet, BZW04-5V8B-E3/73 pinout, BZW04-5V8B-E3/73 application, or BZW04-5V8B-E3/73 equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified TVS for bidirectional overvoltage protection in space-constrained PCB layouts with leaded through-hole mounting.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR min/max, ID leakage, and VC clamping performance across reverse and forward directions. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance under repetitive 10/1000 μs transients at 0.01% duty cycle.
The device complies with AEC-Q101 stress testing for automotive use and supports soldering per JESD 22-B106 (275 °C, 10 s). Its DO-41 package enables compatibility with legacy through-hole assembly while meeting UL 94 V-0 flammability requirements via molded epoxy encapsulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 5.8 V - Maximum continuous operating voltage before conduction begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 6.45–7.14 V at 10 mA - Tight tolerance range ensures predictable turn-on during transient events. |
| VC (Clamping Voltage) | ≤10.5 V at 38 A IPPM - Limits downstream voltage stress during 400 W surge, protecting sensitive ICs. |
| PPPM (Peak Pulse Power) | 400 W (10/1000 μs) - Sustains high-energy surges common in inductive load switching and ESD events. |
| ID (Reverse Leakage) | 1000 μA at VWM - Low leakage preserves signal integrity and minimizes standby power loss in always-on circuits. |
| TJ max | 175 °C - Enables reliable operation in under-hood automotive and high-temperature industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock. |
Pinout & Package
DO-41 (DO-204AL) axial-leaded package with matte tin-plated leads; no polarity marking for bidirectional configuration - 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. |
| Lead 1 / Lead 2 | Mounting interface | Through-hole solder attachment; 0.028–0.034 inch diameter leads support mechanical retention and thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated chip junction | Ensures stable VBR over lifetime and resistance to humidity-induced parameter drift. |
| 400 W peak pulse power (10/1000 μs) | Handles high-energy transients from relay coil collapse or lightning-induced surges without degradation. |
| AEC-Q101 qualification | Validates suitability for automotive applications including engine control modules and body electronics. |
| UL 94 V-0 molding compound | Prevents flame propagation in fault conditions, meeting safety requirements for industrial enclosures. |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between signal line and chassis ground to shunt transient energy. Use Value: Maintains signal integrity during 12 V/24 V system transients by clamping to ≤10.5 V, preventing latch-up or damage to MCU input pins. |

IC Role / Device Role / Timing Role: Fast-response overvoltage clamp on 24 V DC input channels, installed upstream of optocoupler isolation stages. Use Value: Withstands 400 W surges without derating, enabling robust field wiring in factory automation with minimal board area. |
| Consumer Appliance Motor Control | Telecom Line Interface Protection |
Use Scenario: Suppressing back-EMF spikes generated by brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Bidirectional TVS mounted across motor terminals to absorb commutation energy and reduce EMI radiation. Use Value: Glass-passivated junction ensures consistent clamping over 10,000+ motor cycles, supporting extended product warranty periods. |
Use Scenario: Safeguarding Ethernet PHY interfaces and RS-485 transceivers against lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary-level protection device on data line pairs, coordinated with secondary GDT or polymer PTC devices. Use Value: Low clamping voltage (≤10.5 V) prevents overstress of 3.3 V or 5 V transceiver I/O cells during telecom-grade surge tests (IEC 61000-4-5). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Unidirectional; 5.0 V VWM; SMB package (SMT); 600 W PPPM | Requires polarity-aware layout; better suited for high-density PCBs with automated assembly | Select when surface-mount footprint and higher surge rating are prioritized over through-hole serviceability. |
| P6KE6.8A | Unidirectional; 6.8 V VWM; DO-15 package; 600 W PPPM; no AEC-Q101 qualification | Lacks automotive qualification; larger DO-15 body increases board space vs. DO-41 | Choose for cost-sensitive industrial designs where AEC-Q101 is not mandated and higher clamping voltage (11.5 V) is acceptable. |
Compared with BZW04-5V8B-E3/73, SMBJ5.0A-E3/52 offers superior surge handling in a compact SMT form but requires polarity management, while P6KE6.8A provides higher power rating in a less space-efficient through-hole package without automotive qualification - making BZW04-5V8B-E3/73 the optimal choice for AEC-Q101-compliant, bidirectional, space-constrained through-hole designs.

FAQ
What is the polarity configuration of BZW04-5V8B-E3/73?
BZW04-5V8B-E3/73 is a bidirectional TVS diode with symmetrical electrical characteristics in both directions. It has no cathode marking and functions identically regardless of terminal orientation - ideal for AC-coupled or differential signal lines where polarity cannot be guaranteed.
Is BZW04-5V8B-E3/73 qualified for automotive applications?
Yes, BZW04-5V8B-E3/73 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock. This makes it suitable for under-hood and cabin electronics such as engine control units and body control modules.
What does the "E3/73" suffix indicate in BZW04-5V8B-E3/73?
The "E3" denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker-resistant tin plating. The "/73" refers to the packaging option: 73 = 1000-piece bulk pack (as opposed to /54 for tape-and-reel). Both denote Vishay's standard commercial-grade variant.
How does BZW04-5V8B-E3/73 compare to unidirectional TVS diodes like BZW04-5V8-E3/73?
BZW04-5V8B-E3/73 provides identical VWM (5.8 V), VBR (6.45–7.14 V), and VC (≤10.5 V) as its unidirectional counterpart but conducts in both directions. Unlike BZW04-5V8-E3/73, it requires no polarity awareness during placement and protects against voltage reversals - critical in AC or floating signal paths.
What is the maximum junction temperature rating for BZW04-5V8B-E3/73?
The maximum junction temperature (TJ max) for BZW04-5V8B-E3/73 is 175 °C. This allows operation in high-ambient environments such as automotive powertrain compartments or industrial motor drive cabinets, provided PCB copper area and airflow meet thermal derating guidelines in Figure 2 of the datasheet.
