Overview
BZW04P13BHE3/73 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 12.8 V stand-off voltage (VWM), 14.3–16.5 V breakdown voltage (VBR) at 1 mA, 21.2 V clamping voltage (VC) at 19.0 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line surge suppression.
For engineers reviewing the BZW04P13BHE3/73 datasheet, BZW04P13BHE3/73 pinout, BZW04P13BHE3/73 application, or BZW04P13BHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AL (DO-41) package, bi-directional symmetry, low 1.0 μA reverse leakage at VWM, and verified clamping performance under repetitive surge stress.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling single-device protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance and low incremental surge resistance, critical for consistent clamping across temperature and lifetime.
The device complies with ANSI/IEEE C62.35 surge standards and delivers 400 W peak pulse power handling at TA = 25 °C, derating linearly above 25 °C per Fig. 2. Its 175 °C maximum junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive environments and industrial control cabinets subject to thermal cycling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Same DO-214AA package; 13 V VWM, 21.5 V VC @ 19.1 A - nearly identical clamping but higher junction capacitance (~150 pF vs. ~50 pF). | Less suitable for high-speed data lines (e.g., USB, CAN FD); preferred for lower-frequency power rail protection. | Select SMBJ13CA when board space constraints favor SMD mounting and thermal management via PCB copper pour is available. |
| P6KE13CA | DO-15 package; same 13 V VWM and 21.2 V VC, but lower PPPM (600 W) and higher VF - larger footprint, lower surge repetition capability. | Used in legacy industrial designs where through-hole assembly remains standard; not AEC-Q101 qualified. | Choose P6KE13CA only for cost-sensitive, non-automotive applications where AEC-Q101 compliance and compact DO-41 form factor are not required. |
Compared with SMBJ13CA and P6KE13CA, BZW04P13BHE3/73 offers AEC-Q101 qualification, tighter VBR tolerance (±7.5 % vs. ±10 %), lower leakage (1.0 μA vs. 5.0 μA), and optimized DO-41 mechanical robustness for vibration-prone environments - making it the preferred choice for next-generation automotive and industrial edge nodes.

FAQ
What is the maximum clamping voltage of the BZW04P13BHE3/73 under a 10/1000 μs surge?
The BZW04P13BHE3/73 clamps to a maximum of 21.2 V when subjected to its rated 19.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed across the full operating temperature range (-55 °C to +175 °C) and reflects worst-case device behavior per Vishay's characterization data in Document 88316.
Is the BZW04P13BHE3/73 suitable for bi-directional signal line protection?
Yes - the BZW04P13BHE3/73 is explicitly a bi-directional TVS diode (denoted by the "B" suffix), with identical breakdown and clamping characteristics in both polarities. It requires no polarity marking and is ideal for protecting AC-coupled, differential, or floating signal paths such as RS-485, CAN, or audio lines.
Does the HE3 suffix on BZW04P13BHE3/73 indicate AEC-Q101 qualification?
Yes - the "HE3" suffix confirms that the BZW04P13BHE3/73 is AEC-Q101 qualified and RoHS compliant. Per Vishay's ordering documentation, "HE3" denotes the AEC-Q101 qualified commercial grade variant, distinct from the "E3" (non-AEC-Q101) version, and includes JESD201 Class 2 whisker testing.
What is the reverse leakage current of BZW04P13BHE3/73 at its stand-off voltage?
At its 12.8 V stand-off voltage (VWM) and TA = 25 °C, the BZW04P13BHE3/73 exhibits a maximum reverse leakage current (ID) of 1.0 μA. This ultra-low leakage is maintained across its full operating temperature range and supports energy-efficient designs in battery-powered or always-on sensor applications.
Can BZW04P13BHE3/73 replace uni-directional TVS diodes in existing designs?
No - the BZW04P13BHE3/73 is bi-directional and must not be substituted for uni-directional TVS diodes (e.g., BZW04P13HE3) without circuit review. Uni-directional types conduct only in reverse bias and block forward current; using a bi-directional part in their place may cause unintended conduction during normal forward-biased operation.
