Product details
Overview
BZW04-13BHE3/54 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 12.8 V standoff voltage (VWM), 14.3–15.8 V breakdown voltage (VBR) at 1 mA, 21.2 V clamping voltage (VC) at 19 A peak pulse current, 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 BZW04-13BHE3/54 datasheet, BZW04-13BHE3/54 pinout, BZW04-13BHE3/54 application, or BZW04-13BHE3/54 equivalent, this device serves as an AEC-Q101-qualified, RoHS-compliant bidirectional TVS for ESD and surge suppression where low leakage (<1 μA at VWM), fast response, and stable temperature coefficient (0.084 %/°C) are critical.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, enabling consistent clamping performance under repetitive transients.
The device complies with AEC-Q101 for automotive-grade reliability and supports operation from –55 °C to +175 °C junction temperature. Its 10/1000 μs waveform rating reflects standardized surge immunity testing per ANSI/IEEE C62.35, with derating applied above 25 °C ambient per published thermal curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12.8 V - maximum continuous working voltage before conduction begins; defines safe operating margin for protected circuitry. |
| VBR (min/max) | 14.3 V / 15.8 V at 1 mA - precise breakdown threshold ensuring predictable turn-on during overvoltage events. |
| VC @ IPPM | 21.2 V at 19 A - clamping voltage limits downstream voltage stress during 400 W transient surges. |
| IPPM | 19 A - peak pulse current handling capacity with 10/1000 μs waveform, defining surge energy absorption capability. |
| PPPM | 400 W - peak pulse power rating indicating transient energy dissipation capacity without failure. |
| TJ max. | +175 °C - maximum junction temperature enabling use in under-hood automotive and high-temperature industrial environments. |
| Leakage (ID) | <1 μA at VWM - negligible standby current preserves signal integrity and power efficiency in always-on circuits. |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN, LIN, or analog sensor lines (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector entry point to shunt transients before reaching MCU or signal conditioner. Use Value: Prevents latch-up or damage to 3.3 V/5 V interface ICs while maintaining <1 μA leakage to avoid signal offset errors. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to inductive switching noise from solenoids and relays. IC Role / Device Role / Timing Role: Front-end transient suppressor on 24 V DC input channels, coordinated with series impedance for IEC 61000-4-4 compliance. Use Value: Clamps 1 kV/50 Ω surges to ≤21.2 V within nanoseconds, preserving input logic thresholds and reducing false triggering. |
| Telecom Line Interface | Consumer Appliance Control Board |
Use Scenario: Shielding RS-485 transceivers and Ethernet PHYs in base station backhaul equipment from lightning-induced surges. IC Role / Device Role / Timing Role: Secondary-level protection stage after gas discharge tube (GDT), providing low-clamp refinement for fast-rising edges. Use Value: Limits transient overshoot to 21.2 V at 19 A, enabling use of lower-voltage-rated transceivers without sacrificing surge margin. |
Use Scenario: Securing microcontroller GPIOs and display driver lines in washing machines and HVAC controllers against ESD from user interaction. IC Role / Device Role / Timing Role: Localized TVS on front-panel buttons, touch sensors, and motor driver feedback paths. Use Value: Withstands ±8 kV contact ESD (IEC 61000-4-2) with sub-nanosecond response, preventing firmware resets or display corruption. |
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 | DO-214AA package; 13 V VWM, 21.5 V VC @ 17.9 A; same 400 W PPPM but higher capacitance (~150 pF vs. ~50 pF for BZW04-13BHE3/54). | Preferred for surface-mount PCBs; less suitable for through-hole legacy designs or high-frequency signal lines due to higher junction capacitance. | Select SMBJ13CA when board space is constrained and SMT assembly is available; verify layout clearance for thermal relief under surge conditions. |
| P6KE13CA | DO-15 package; 13 V VWM, 23.2 V VC @ 17.3 A; 600 W PPPM rating but larger footprint and higher VC than BZW04-13BHE3/54. | Better for higher-energy surges but introduces greater voltage overshoot; not AEC-Q101 qualified. | Choose P6KE13CA only if system-level testing confirms 23.2 V clamping is acceptable and automotive qualification is not required. |
Compared with SMBJ13CA and P6KE13CA, BZW04-13BHE3/54 offers AEC-Q101 qualification, lower clamping voltage (21.2 V), and tighter VBR tolerance (±5 %) in a compact DO-41 through-hole package - making it optimal for cost-sensitive, high-reliability automotive and industrial replacements where leaded mounting and precise clamping are prioritized.

FAQ
What is the polarity configuration of BZW04-13BHE3/54?
BZW04-13BHE3/54 is a bidirectional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional variants, it has no cathode marking and functions identically regardless of terminal orientation - essential for AC-coupled or differential signal protection where polarity is undefined.
Is BZW04-13BHE3/54 qualified for automotive use?
Yes, BZW04-13BHE3/54 carries the HE3 suffix, confirming AEC-Q101 qualification per the Vishay datasheet (Document Number 88316, Revision 16-Sep-2021). This certification validates its reliability for automotive applications including engine control, body electronics, and ADAS sensor interfaces under extended temperature and vibration stress.
What does the "/54" in BZW04-13BHE3/54 indicate?
The "/54" denotes the preferred packaging code: 13-inch diameter paper tape and reel containing 550 units. This format is optimized for automated pick-and-place assembly and aligns with standard logistics handling for high-volume manufacturing of BZW04-13BHE3/54 in DO-41 packages.
How does BZW04-13BHE3/54 compare to unidirectional BZW04-13HE3/54?
BZW04-13BHE3/54 differs from the unidirectional BZW04-13HE3/54 by supporting symmetrical transient suppression in both directions, with identical VBR, VC, and PPPM ratings. The unidirectional version includes a cathode band and is rated for forward surge current (IFSM = 40 A), while the bidirectional variant omits this rating and has no polarity marking.
What is the maximum junction temperature rating for BZW04-13BHE3/54?
The maximum junction temperature (TJ) for BZW04-13BHE3/54 is +175 °C, as specified in the Vishay datasheet. This enables reliable operation in under-hood automotive environments and high-temperature industrial enclosures, with thermal derating applied above 25 °C ambient per Figure 2 of Document Number 88316.
