Product details
Overview
BZW04P136B-E3/73 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 BZW04P136B-E3/73 datasheet, BZW04P136B-E3/73 pinout, BZW04P136B-E3/73 application, or BZW04P136B-E3/73 equivalent, key selection criteria include its bi-directional symmetry, AEC-Q101 qualification, DO-41 package compatibility, and precise clamping performance under repetitive surge conditions.
Technical Context
This device operates as a voltage-clamped shunt protector: during transients exceeding 136 V, it avalanches symmetrically in both directions to clamp the line at ≤219 V while diverting up to 1.8 A (10/1000 μs). Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Designed for high-reliability environments, BZW04P136B-E3/73 maintains operation across –55 °C to +175 °C junction temperature, supports soldering per JESD 22-B106 (275 °C, 10 s), and meets RoHS and AEC-Q101 requirements - confirming suitability for under-hood automotive and industrial control applications.

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, 219 V VC @ 1.8 A; same PPPM but higher capacitance (150 pF vs. ~50 pF) | Surface-mount layout; less suitable for through-hole legacy designs or high-vibration mechanical mounting | Select when board space is constrained and reflow assembly is used; verify PCB pad thermal relief for 1.5 W steady-state dissipation |
| P6SMB130CA | Same DO-214AA package; 130 V VWM, 219 V VC @ 1.8 A; lower surge rating (600 W vs. 400 W) and non-AEC-Q101 | Commercial-grade only; not qualified for automotive temperature cycling or humidity testing | Acceptable for cost-sensitive industrial controls where AEC-Q101 is not mandated; avoid in automotive Tier-1 supply chains |
Compared with SMBJ130CA and P6SMB130CA, BZW04P136B-E3/73 offers through-hole mechanical robustness, AEC-Q101 validation, and tighter VWM tolerance (136 V vs. 130 V), making it preferable for automotive and high-reliability industrial deployments requiring long-term solder joint integrity.

FAQ
What is the clamping voltage of BZW04P136B-E3/73 under standard test conditions?
The BZW04P136B-E3/73 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 IEC 61000-4-5 and ensures predictable overvoltage limiting for downstream 150 V-rated components. The clamping performance is symmetric and validated across the full operating temperature range.
Is BZW04P136B-E3/73 qualified for automotive applications?
Yes, BZW04P136B-E3/73 is AEC-Q101 qualified, having passed stress tests including temperature cycling, humidity bias, and high-temperature operating life. Its DO-41 package and 175 °C maximum junction temperature make it suitable for under-hood and chassis-mounted automotive modules such as body control units and sensor interface boards.
Does BZW04P136B-E3/73 have polarity markings?
No, BZW04P136B-E3/73 is a bi-directional TVS diode and carries no polarity marking - the device functions identically regardless of installation orientation. This eliminates risk of incorrect placement during manual or automated assembly and simplifies layout for AC-coupled or floating signal paths.
What is the maximum steady-state power dissipation for BZW04P136B-E3/73?
The BZW04P136B-E3/73 has a maximum power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at lead temperature TL = 75 °C. In typical PCB layouts with 1 oz copper and moderate thermal relief, derating to ≤0.8 W is recommended for continuous operation to maintain junction temperature below 175 °C.
How does the breakdown voltage tolerance of BZW04P136B-E3/73 compare to similar TVS diodes?
BZW04P136B-E3/73 specifies a breakdown voltage (VBR) range of 152 V to 176 V at 1 mA test current - a ±8.2% tolerance centered on 164 V nominal. This tighter spread versus generic 15% tolerance devices improves system-level predictability in coordinated protection schemes involving upstream fuses or GDTs.
