Product details
Overview
BZW04P136BHE3/73 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 stand-off voltage (VWM), 219 V maximum 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 BZW04P136BHE3/73 datasheet, BZW04P136BHE3/73 pinout, BZW04P136BHE3/73 application, or BZW04P136BHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-41 package compatibility, bi-directional surge handling up to ±219 V, and low 1.0 μA reverse leakage at VWM - critical for low-power, high-reliability DC bus and data line protection.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 152 V and 176 V at 1 mA test current. Its clamping behavior is validated under standardized 10/1000 μs surge waveforms per ANSI/IEEE C62.35, ensuring predictable voltage limiting during ESD and lightning-induced transients.
The device uses a glass-passivated silicon junction and is qualified to AEC-Q101 for automotive use. Thermal derating follows a defined curve down to zero power at 175 °C junction temperature, and its 0.108 %/°C VBR temperature coefficient ensures stable threshold performance across operating ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 152–176 V at 1 mA - precise voltage range where avalanche conduction initiates; ensures consistent turn-on across units |
| VC (Clamping Voltage) | 219 V at IPPM = 1.8 A - peak voltage seen by protected circuit during 10/1000 μs surge; limits stress on downstream ICs |
| PPPM (Peak Pulse Power) | 400 W - energy-handling capacity for transient suppression; supports repetitive surges at 0.01 % duty cycle |
| ID (Reverse Leakage) | 1.0 μA at VWM - ultra-low leakage preserves signal integrity and battery life in always-on circuits |
| TJ max. | 175 °C - extended junction temperature rating enables deployment in under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |
Pinout & Package
Package: DO-204AL (DO-41), axial-leaded, epoxy-molded case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards. No polarity marking - bi-directional operation confirmed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional avalanche junction | No functional distinction between leads; either terminal serves as input/output for transient energy diversion |
| Lead 1 / Lead 2 | Current path for surge conduction | Leads conduct bidirectional surge current to ground or rail; no internal series resistance or control logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | DO-214AA package; 130 V VWM; 220 V VC at 1.8 A; same 400 W PPPM but higher capacitance (150 pF vs. ~50 pF) | Surface-mount layout; less suitable for through-hole legacy designs or high-frequency signal lines due to higher junction capacitance | Select when SMT assembly is required and board space is constrained; verify layout clearance for SMB footprint |
| P6KE150CA | DO-15 package; 150 V VWM; 243 V VC at 1.6 A; lower peak pulse current rating and wider VBR tolerance (143–165 V) | Legacy through-hole design; lower surge robustness and looser voltage tolerance reduce margin in precision 136 V systems | Acceptable for non-automotive cost-sensitive applications where AEC-Q101 is not mandated and 13 V VWM margin is acceptable |
Compared with SMBJ130CA and P6KE150CA, BZW04P136BHE3/73 offers tighter VBR (152–176 V), lower leakage (1.0 μA), AEC-Q101 qualification, and DO-41 mechanical compatibility - making it optimal for new automotive and industrial through-hole designs requiring high confidence in clamping consistency and long-term reliability.

FAQ
What is the maximum clamping voltage of the BZW04P136BHE3/73 under standard surge conditions?
The BZW04P136BHE3/73 has a maximum clamping voltage (VC) of 219 V when subjected to a 10/1000 μs surge waveform at 1.8 A peak pulse current. This value is measured per ANSI/IEEE C62.35 and guarantees that protected circuitry will not experience voltages exceeding 219 V during standardized transient events - a critical parameter for safeguarding 150 V-rated components downstream.
Is the BZW04P136BHE3/73 suitable for automotive applications?
Yes, the BZW04P136BHE3/73 is AEC-Q101 qualified and specifically designed for automotive use. Its HE3 suffix denotes compliance with JESD201 Class 2 whisker resistance, RoHS, and full AEC-Q101 stress testing - including temperature cycling, high-temperature reverse bias, and ESD. It is deployed in engine control units, body electronics, and ADAS sensor interfaces where reliability under thermal and electrical stress is essential.
How does the bi-directional nature of the BZW04P136BHE3/73 affect its PCB layout?
The BZW04P136BHE3/73 has no polarity marking and functions identically in both directions, simplifying PCB layout by eliminating orientation constraints. Engineers may place it across any two nodes requiring symmetrical overvoltage protection - such as differential signal pairs, AC-coupled lines, or ungrounded DC rails - without concern for anode/cathode alignment. Its DO-41 axial package supports straightforward through-hole routing.
What is the reverse leakage current specification for the BZW04P136BHE3/73 at its rated stand-off voltage?
The BZW04P136BHE3/73 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its 136 V stand-off voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage preserves signal integrity in high-impedance circuits and minimizes standby power loss - especially important in battery-powered automotive sensors and industrial IoT edge nodes where quiescent current budgets are tightly constrained.
Does the BZW04P136BHE3/73 require heatsinking for normal operation?
No, the BZW04P136BHE3/73 does not require external heatsinking during transient suppression events because its 400 W peak pulse power rating applies to short-duration, non-repetitive surges (duty cycle ≤ 0.01 %). Its 1.5 W steady-state power dissipation (PD) is managed via standard PCB copper; however, sustained power dissipation above PD requires thermal analysis per the derating curve in Figure 5 of the datasheet.
