Product details
Overview
BZW04P58BHE3/73 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 58.1 V stand-off voltage (VWM), 92.0 V maximum clamping voltage (VC) at 4.3 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) capability with 10/1000 µs waveform - ideal for safeguarding automotive sensor interfaces and industrial I/O circuits against ESD and inductive switching transients.
For engineers reviewing the BZW04P58BHE3/73 datasheet, BZW04P58BHE3/73 pinout, BZW04P58BHE3/73 application, or BZW04P58BHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AL (DO-41) axial package, bi-directional symmetry, low 0.104 %/°C VBR temperature coefficient, and verified performance under repetitive 0.01% duty cycle surge conditions.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 64.6 V and 74.8 V at 1 mA test current, ensuring consistent clamping behavior regardless of transient polarity. Its glass-passivated junction delivers fast response time (<1 ns) and low incremental surge resistance, critical for protecting sensitive downstream circuitry.
The device is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient per Figure 2; it supports soldering up to 275 °C for 10 s (JESD22-B106) and meets JESD201 Class 2 whisker resistance (HE3 suffix). Its 1.5 W steady-state power dissipation (PD) enables reliable operation in continuous bias applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58.1 V - maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR min/max | 64.6 V / 74.8 V at 1 mA - tight breakdown window ensures predictable turn-on and minimal overshoot during transients. |
| VC @ IPPM | 92.0 V at 4.3 A (10/1000 µs) - clamping voltage limits energy delivered to protected ICs; critical for MOSFET gate or MCU I/O survival. |
| PPPM | 400 W - peak pulse power handling capacity under standardized surge waveform; validates robustness against IEC 61000-4-5 Level 3/4 surges. |
| ID @ VWM | 1.0 µA - ultra-low reverse leakage at stand-off voltage preserves signal integrity and minimizes standby power loss. |
| TJ max | 175 °C - high-temperature rating supports under-hood automotive and industrial environments without thermal derating penalties. |
| Package | DO-204AL (DO-41) - industry-standard axial leaded package with matte tin-plated leads, UL 94 V-0 molding compound, and AEC-Q101 qualification. |
Pinout & Package
DO-204AL (DO-41) axial package: cylindrical epoxy body with two tinned axial leads; no polarity marking (bi-directional); lead diameter 0.58–0.66 mm; overall length ≥25.4 mm; body diameter 2.0–2.7 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional transient conduction path | No functional distinction - either lead serves as input/output; identical clamping in both directions simplifies PCB layout and eliminates orientation errors. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for engine control, ADAS, and body electronics. |
| Glass passivated junction | Enables <1 ns response time and stable VBR over lifetime - essential for suppressing fast-rising ESD events (IEC 61000-4-2) before damage occurs. |
| 400 W peak pulse power (10/1000 µs) | Withstands repeated high-energy transients from inductive load switching (e.g., solenoids, relays) without degradation. |
| RoHS-compliant, matte tin plating | Meets J-STD-002/JESD22-B102 solderability standards and JESD201 Class 2 whisker resistance - ensures long-term interconnect reliability in automated assembly. |
| Low temperature coefficient (0.104 %/°C) | Minimizes VBR drift across -55 °C to +175 °C operating range - maintains consistent protection threshold in extreme thermal environments. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bi-directional clamping element placed at connector interface to shunt surge energy before reaching signal conditioning ICs. Use Value: Prevents latch-up or permanent damage to 5 V/12 V sensor front-ends while maintaining <1 µA leakage to avoid measurement offset errors. |
Use Scenario: Safeguarding digital input modules against 2 kV/1 A surge transients induced by relay coil de-energization in factory automation systems. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC input lines, coordinated with series impedance to limit let-through energy. Use Value: Enables compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity requirements without adding active circuitry. |
| Telecom Line Interface | Consumer Power Adapter Output |
Use Scenario: Shielding Ethernet PHY magnetics and PoE controller inputs from lightning-induced surges on outdoor data lines. IC Role / Device Role / Timing Role: Secondary-level protector downstream of gas discharge tube (GDT), providing low-clamp refinement. Use Value: Reduces VC to 92.0 V - well below typical 100 V Ethernet IC absolute maximum ratings - preventing catastrophic failure. |
Use Scenario: Suppressing output voltage spikes caused by transformer leakage inductance during AC/DC adapter startup or short-circuit recovery. IC Role / Device Role / Timing Role: Parallel-connected TVS across secondary-side rectifier output to clamp overshoot before reaching USB-PD or battery charging ICs. Use Value: Limits transient excursions to ≤92.0 V, protecting 20 V-rated USB-C PD controllers and avoiding false overvoltage shutdowns. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | Same DO-214AA package; 58 V VWM, 93.6 V VC @ 4.3 A; 600 W PPPM; higher clamping voltage and larger footprint. | Preferred where board space allows SMC/SMB packages and higher surge margin is needed; not drop-in due to different package and thermal profile. | Select SMBJ58CA when higher peak power handling is required and PCB layout accommodates surface-mount footprint. |
| P6KE56CA | DO-15 package; 56 V VWM, 93.6 V VC @ 4.3 A; 600 W PPPM; older platform with wider VBR tolerance (±10%) and no AEC-Q101 qualification. | Suitable for commercial-grade power supplies but lacks automotive qualification and tighter VBR control. | Choose P6KE56CA only for cost-sensitive non-automotive designs where AEC-Q101 and tight VBR are not mandatory. |
Compared with SMBJ58CA and P6KE56CA, BZW04P58BHE3/73 offers AEC-Q101 qualification, tighter VBR tolerance (±7.7%), lower clamping voltage (92.0 V vs. 93.6 V), and axial DO-41 form factor enabling through-hole mounting in high-vibration environments - making it the preferred choice for automotive and harsh industrial applications requiring proven reliability and precise clamping.
