Product details
Overview
BZW04P136HE3/73 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 136 V standoff voltage (VWM), 219 V clamping voltage (VC) at 1.8 A peak pulse current, 400 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability - deployed in CAN bus interface protection and sensor supply rail conditioning.
For engineers reviewing the BZW04P136HE3/73 datasheet, BZW04P136HE3/73 pinout, BZW04P136HE3/73 application, or BZW04P136HE3/73 equivalent, key selection criteria include its bi-directional clamping behavior, DO-41 package compatibility with high-surge industrial layouts, low leakage (<1 μA at 136 V), and temperature coefficient of breakdown voltage (0.108 %/°C) critical for thermal-stable ESD hardening.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM), then avalanches rapidly (<1 ns response) when transients exceed its 152–176 V breakdown range (VBR at 1 mA). Its glass-passivated junction ensures stable leakage and repeatable clamping across -55 °C to +175 °C operating range.
The bi-directional architecture enables symmetric suppression on AC-coupled or floating lines without polarity concerns, while its 1.5 W steady-state power dissipation (PD) and 400 W transient rating support repetitive surge handling in motor drive feedback paths and automotive LIN/CAN node protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - maximum continuous reverse working voltage before clamping initiates; defines safe operating margin for 12 V/24 V/48 V system rails. |
| VC @ IPPM | 219 V at 1.8 A - clamped voltage during 10/1000 μs surge; limits downstream IC stress to <220 V in automotive load-dump scenarios. |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity. |
| VBR Range | 152–176 V at 1 mA - verified breakdown window ensures consistent turn-on across production lots and temperature. |
| ID @ VWM | <1 μA - ultra-low reverse leakage preserves battery life in always-on automotive modules and sensor nodes. |
| TJ Max | +175 °C - junction temperature rating enables placement near heat sources (e.g., power MOSFETs, engine control units). |
| AEC-Q101 | Qualified - validated for automotive electronic systems including powertrain, body control, and ADAS sensor interfaces. |

IC Role / Device Role / Timing Role: Bi-directional shunt clamp placed directly at connector entry point to divert surge energy before reaching CAN transceiver. Use Value: Clamps transients to ≤219 V while maintaining <1 μA leakage - preserves common-mode range and avoids false dominant states in CAN FD networks. |
Use Scenario: Safeguarding analog output (4–20 mA) or digital I²C/SPI lines from inductive switching noise in factory automation PLCs. IC Role / Device Role / Timing Role: Standoff-rated TVS on sensor supply and data lines to suppress coupled transients from solenoid valves or relay coils. Use Value: 136 V VWM allows use on 24 V industrial rails with 30 % safety margin; DO-41 footprint enables retrofit into legacy PCB layouts. |
| Power Supply Input Stage | Telecom Line Interface |
Use Scenario: Secondary-side overvoltage protection on DC-DC converter outputs feeding FPGA or microcontroller core supplies. IC Role / Device Role / Timing Role: Fast-response clamp limiting output rail excursions during startup faults or feedback loop failure. Use Value: 1.8 A IPPM capability handles 100 ms overvoltage events without thermal runaway; 175 °C TJ max supports compact heatsink-free designs. |
Use Scenario: Primary protection for Ethernet PHY or xDSL line drivers exposed to lightning-induced surges (IEC 61000-4-5 2 kV line-earth). IC Role / Device Role / Timing Role: First-stage shunt suppressor on twisted-pair inputs, coordinated with GDT or polymer PTC upstream. Use Value: Symmetric bi-directional clamping maintains signal integrity on AC-coupled lines; low capacitance (<100 pF) avoids bandwidth degradation above 10 MHz. |
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; 219 V VC @ 1.8 A; SMB package (surface-mount) | Requires polarity-aware layout; unsuitable for AC or floating lines without external biasing. | Select when board space is constrained and circuit topology guarantees unidirectional voltage polarity. |
| P6KE150CA | Bi-directional; 150 V VWM; 243 V VC @ 1.6 A; DO-15 package (larger than DO-41) | Higher clamping voltage reduces protection margin for 136 V-rated systems; 0.5 g unit weight vs. 0.35 g for BZW04P136HE3/73. | Choose only if existing DO-15 footprint must be retained and 243 V VC is acceptable for downstream component ratings. |
Compared with SMBJ130A and P6KE150CA, BZW04P136HE3/73 delivers tighter VWM tolerance (136 V exact), lower clamping voltage (219 V), smaller DO-41 footprint, and AEC-Q101 qualification - making it the preferred choice for new automotive and high-reliability industrial designs requiring bi-directional surge immunity.

FAQ
What is the clamping voltage of BZW04P136HE3/73 under standard surge conditions?
The BZW04P136HE3/73 has a maximum clamping voltage (VC) of 219 V when subjected to a 10/1000 μs waveform with a peak pulse current (IPPM) of 1.8 A. This value is measured per IEC 61000-4-5 test conditions and ensures downstream components see limited overvoltage stress during surge events. The clamping performance is guaranteed across the full operating temperature range of -55 °C to +175 °C.
Is BZW04P136HE3/73 suitable for automotive applications?
Yes, BZW04P136HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use. Its DO-41 package with HE3 suffix meets JESD201 Class 2 whisker resistance, and its 175 °C maximum junction temperature supports under-hood deployment. The device is commonly used in CAN/LIN bus protection, body control modules, and ADAS sensor interfaces where bi-directional surge immunity is required.
How does the bi-directional nature of BZW04P136HE3/73 affect its PCB layout?
The bi-directional design of BZW04P136HE3/73 means it has no polarity marking and can be mounted in either orientation on the PCB. This simplifies assembly, eliminates risk of reverse installation, and enables use on AC-coupled or floating signal lines such as differential buses (CAN, RS-485) or transformer-isolated interfaces. No cathode band or silkscreen polarity indicator is needed.
What is the maximum steady-state power dissipation for BZW04P136HE3/73?
The BZW04P136HE3/73 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at lead temperature (TL) of 75 °C. In typical through-hole applications without heatsinking, derating applies per Figure 5 in the datasheet - e.g., ~0.8 W at TL = 100 °C. This rating governs continuous leakage-based heating, not transient surge handling.
Does BZW04P136HE3/73 meet RoHS and REACH requirements?
Yes, BZW04P136HE3/73 carries the HE3 suffix, confirming full compliance with RoHS Directive 2011/65/EU and alignment with WEEE 2002/96/EC.
