Product details
Overview
BZW04P136BHE3/54 from Vishay General Semiconductor is a bi-directional TransZorb® transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a 136 V standoff voltage (VWM), 219 V clamping voltage (VC) at 1.8 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line cards.
For engineers reviewing the BZW04P136BHE3/54 datasheet, BZW04P136BHE3/54 pinout, BZW04P136BHE3/54 application, or BZW04P136BHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, DO-41 package compatibility, bi-directional surge handling up to ±1.8 A, and low temperature coefficient (0.108 %/°C) ensuring stable clamping across operating temperatures.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, delivering consistent clamping performance without polarity dependency. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing ESD and lightning-induced transients per IEC 61000-4-2/4-5.
The device is rated for 175 °C maximum junction temperature and derates linearly above 25 °C ambient, supporting reliable operation in under-hood automotive and high-temperature industrial environments. Its 1.0 mA test current (IT) and 1.0 μA reverse leakage (ID) at VWM reflect tight parametric control for precision protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - Maximum continuous working voltage before clamping begins; defines safe operating margin for 120 VAC-derived DC rails. |
| VC @ IPPM | 219 V at 1.8 A - Clamped voltage during 10/1000 μs surge; ensures downstream ICs see <220 V stress during worst-case transients. |
| PPPM | 400 W - Peak pulse power handling with 10/1000 μs waveform; supports repetitive surge events at 0.01% duty cycle. |
| VBR min/max | 152 V / 176 V at 1.0 mA - Breakdown voltage range confirms tight manufacturing tolerance for predictable turn-on behavior. |
| TJ max | 175 °C - Maximum junction temperature; enables use in high-ambient environments like engine control units and power supplies. |
| Temp. coeff. | 0.108 %/°C - Low voltage drift with temperature; maintains clamping accuracy across -55 °C to +175 °C operating range. |
| AEC-Q101 | Qualified - Certified for automotive applications per stress test requirements including HTOL, TC, and ESD. |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog sensor outputs (e.g., pressure, temperature) in engine control modules from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bi-directional TVS clamp placed between sensor output and microcontroller ADC input. Use Value: Limits transient voltage to ≤219 V while maintaining signal integrity via low capacitance and fast response. |

IC Role / Device Role / Timing Role: Primary overvoltage suppression element on each isolated input channel before optocoupler or Schmitt trigger. Use Value: Absorbs 400 W surges without latch-up, enabling compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge). |
| Telecom Line Interface | Power Supply Input Stage |
Use Scenario: Shielding Ethernet PHY interface circuitry (e.g., PoE-powered devices) against lightning-induced common-mode surges on twisted-pair lines. IC Role / Device Role / Timing Role: Bi-directional TVS connected across differential pair (e.g., TX+/TX−) to clamp mode conversion transients. Use Value: Symmetric clamping ensures balanced suppression without skewing differential signaling integrity. |
Use Scenario: Secondary-level protection on 136–176 V intermediate bus rails in telecom rectifiers and industrial SMPS front-ends. IC Role / Device Role / Timing Role: Standoff-rated TVS placed after primary MOV but before DC-DC converter input filter. Use Value: Precise 136 V VWM avoids nuisance triggering while providing fail-safe clamping at 219 V during overvoltage faults. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Uni-directional; 130 V VWM; DO-214AA package; 600 W PPPM; higher VC (213 V @ 2.7 A) | Requires polarity-aware placement; better suited for unidirectional DC rails with higher surge margin. | Select when higher peak power and surface-mount packaging are prioritized over bi-directionality. |
| P6SMB130A | Uni-directional; 130 V VWM; DO-214AA; 600 W PPPM; VF = 3.5 V; no AEC-Q101 qualification | Lacks automotive qualification; intended for commercial/industrial use only; lower cost. | Choose for non-automotive applications where AEC-Q101 is not required and board space favors SMD. |
Compared with BZW04P136BHE3/54, SMBJ130A offers higher surge power in a compact SMD package but requires polarity-aware layout and lacks bi-directional symmetry, while P6SMB130A provides cost-effective uni-directional protection without automotive qualification - making BZW04P136BHE3/54 the optimal choice for AEC-Q101-compliant, bi-directional, through-hole designs.

FAQ
What is the clamping voltage of BZW04P136BHE3/54 under standard surge conditions?
The BZW04P136BHE3/54 exhibits a maximum clamping voltage (VC) of 219 V when subjected to its rated peak pulse current of 1.8 A with a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and ensures protected circuitry remains below critical voltage thresholds during transient events. The clamping performance is verified across the full operating temperature range and is integral to the device's design for automotive and industrial surge immunity.
Is BZW04P136BHE3/54 suitable for automotive applications?
Yes, BZW04P136BHE3/54 is AEC-Q101 qualified and specifically designed for automotive use. Its qualification covers high-temperature operation up to 175 °C, thermal cycling, mechanical shock, and ESD robustness - making it appropriate for engine control units, body electronics, and ADAS sensor interfaces. The HE3 suffix confirms compliance with JESD201 Class 2 whisker resistance and RoHS requirements for automotive manufacturing.
How does the bi-directional nature of BZW04P136BHE3/54 affect its PCB layout?
The bi-directional configuration of BZW04P136BHE3/54 eliminates polarity marking - both leads are functionally identical, allowing placement without orientation constraints. This simplifies layout for AC-coupled or floating nodes (e.g., RS-485, CAN, audio lines) and avoids errors in high-volume assembly. Unlike uni-directional TVS diodes, BZW04P136BHE3/54 requires no cathode band alignment, reducing design review overhead and field failure risk.
What is the standoff voltage (VWM) specification for BZW04P136BHE3/54, and why is it important?
The standoff voltage (VWM) of BZW04P136BHE3/54 is 136 V - the maximum continuous DC or RMS voltage the device can withstand without entering breakdown. This parameter ensures reliable operation under normal conditions while providing sufficient margin above system operating voltage (e.g., 120 VAC-derived rails). Exceeding VWM risks premature conduction and power dissipation, so proper VWM selection relative to system voltage is essential for stable, low-leakage protection.
Does BZW04P136BHE3/54 have a specified junction capacitance, and how does it impact high-speed signal lines?
Junction capacitance is not explicitly specified for BZW04P136BHE3/54 in the provided documentation. However, as a DO-41 packaged TVS diode optimized for power-line and medium-speed signal protection (not RF or >100 Mbps data lines), its capacitance is inherently higher than SMD ultra-low-capacitance TVS devices. For high-speed interfaces like USB or HDMI, designers should verify signal integrity separately or select purpose-built low-CJ TVS arrays - BZW04P136BHE3/54 is best applied to DC power rails and low-to-medium frequency signal paths such as sensor analog outputs or 24 V digital I/O.
