Product details
Overview
BZW04-136BHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of signal and power lines. It features a 136 V standoff voltage (VWM), 152–168 V breakdown range (VBR at 1 mA), 219 V clamping voltage at 1.8 A peak pulse current (IPPM), and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the BZW04-136BHE3/54 datasheet, BZW04-136BHE3/54 pinout, BZW04-136BHE3/54 application, or BZW04-136BHE3/54 equivalent, this device serves as an AEC-Q101-qualified, RoHS-compliant bidirectional TVS for high-reliability transient suppression where precise clamping, low leakage (<1.0 μA), and stable temperature coefficient (0.108 %/°C) are critical.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR and low incremental surge resistance across temperature.
The device delivers 400 W peak pulse power handling per 10/1000 μs waveform at TA = 25 °C, derating linearly above 25 °C per Fig. 2, and supports operating junction temperatures from –55 °C to +175 °C - making it suitable for under-hood automotive and harsh industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - maximum continuous DC or RMS voltage the device blocks without significant leakage |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - precise voltage threshold at which avalanche conduction begins in either direction |
| VC (Clamping Voltage) | 219 V at IPPM = 1.8 A - peak voltage seen by protected circuit during worst-case transient |
| IPPM (Peak Pulse Current) | 1.8 A - maximum non-repetitive surge current the device safely clamps per 10/1000 μs waveform |
| PPPM (Peak Pulse Power) | 400 W - transient energy absorption capability under standardized surge conditions |
| ID (Reverse Leakage) | <1.0 μA at VWM - minimal loading on high-impedance signal lines during normal operation |
| Temperature Coefficient | 0.108 %/°C - predictable VBR drift over temperature, critical for precision protection design |

Applications
| Automotive Sensor Protection | Industrial PLC Analog Inputs |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential or single-ended signal lines upstream of interface ICs. Use Value: Limits transient voltage to ≤219 V while maintaining <1.0 μA leakage at 136 V - preserving signal integrity and preventing latch-up in downstream ASICs. |

| Telecom Line Interface | Consumer Appliance Motor Control |
Use Scenario: Shielding RS-485/RS-422 transceivers in base station backhaul and network equipment from lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Secondary-level protection device used alongside GDTs or polymer PTCs in multi-stage telecom surge circuits. Use Value: Provides precise 136 V standoff and 219 V clamping to avoid false triggering while ensuring fail-safe shutdown below IC absolute maximum ratings. |
Use Scenario: Suppressing commutation spikes from brushed DC motors and solenoids in washing machines, HVAC actuators, and power tools. IC Role / Device Role / Timing Role: Snubber-style clamp across motor terminals or relay coils to limit inductive kickback voltage.

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-E3/52 | Unidirectional; 130 V VWM; SMA package; 600 W PPPM; higher IPPM (32.4 A) | Requires polarity-aware placement; better suited for DC-biased rails with higher surge margin | Select when unidirectional clamping and higher surge capacity are needed, and board space allows SMA footprint |
| P6SMB130AHE3/A | Unidirectional; 130 V VWM; same DO-41 package; 600 W PPPM; AEC-Q101 qualified | Lacks bidirectional symmetry; requires cathode orientation; higher clamping (214 V at 2.8 A) | Choose for cost-sensitive automotive applications where polarity is fixed and 214 V clamping is acceptable |
Compared with BZW04-136BHE3/54, SMBJ130A-E3/52 offers higher surge capacity but demands polarity-aware layout and surface-mount assembly, while P6SMB130AHE3/A matches the DO-41 form factor but sacrifices bidirectional flexibility and exhibits slightly lower clamping performance - making BZW04-136BHE3/54 optimal for floating or AC-coupled protection where symmetry and AEC-Q101 compliance are mandatory.

FAQ
What is the polarity configuration of BZW04-136BHE3/54?
BZW04-136BHE3/54 is a bidirectional TVS diode with symmetrical avalanche characteristics in both directions. It has no polarity marking on the DO-41 package, and its terminals are interchangeable in circuit design - ideal for protecting AC-coupled or floating signal paths where voltage transients may occur with either polarity.
Is BZW04-136BHE3/54 qualified for automotive use?
Yes, BZW04-136BHE3/54 carries the HE3 suffix, indicating it is RoHS-compliant and AEC-Q101 qualified. This certification validates its reliability under automotive-grade temperature cycling, humidity, mechanical shock, and surge stress - making it suitable for engine control units, body electronics, and ADAS sensor modules.
What is the clamping voltage of BZW04-136BHE3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-136BHE3/54 is 219 V at a peak pulse current (IPPM) of 1.8 A, measured with a 10/1000 μs waveform. This value represents the highest voltage the protected circuit will experience during a standardized transient event - critical for ensuring downstream ICs remain within their absolute maximum ratings.
How does the temperature coefficient affect BZW04-136BHE3/54 performance?
BZW04-136BHE3/54 has a maximum temperature coefficient of VBR of 0.108 %/°C. This means its breakdown voltage increases predictably with junction temperature - for example, a +50 °C rise above 25 °C increases VBR by ~5.4 V. Designers must account for this drift when setting safety margins in high-temperature environments like under-hood automotive applications.
What packaging format is used for BZW04-136BHE3/54?
BZW04-136BHE3/54 is supplied in 13-inch diameter paper tape and reel packaging (package code 54), with a base quantity of 550 units per reel. The HE3 suffix confirms RoHS compliance and AEC-Q101 qualification, and the device uses matte tin-plated leads compatible with standard reflow and wave soldering processes per J-STD-002 and JESD22-B102.
