Product details
Overview
BZW04P11BHE3/54 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 11.1 V stand-off voltage (VWM), 12.4–14.3 V breakdown range (VBR at 1 mA), 18.2 V clamping voltage (VC) at 22 A peak pulse current, 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification - making it suitable for automotive sensor interface and industrial control bus protection.
For engineers reviewing the BZW04P11BHE3/54 datasheet, BZW04P11BHE3/54 pinout, BZW04P11BHE3/54 application, or BZW04P11BHE3/54 equivalent, key selection criteria include its bi-directional clamping behavior, DO-41 package compatibility, low leakage (<1 µA at VWM), temperature coefficient of 0.081 %/°C, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity standards.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, delivering consistent clamping performance without polarity dependence. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable breakdown characteristics across -55 °C to +175 °C operating junction temperature.
The device uses a DO-204AL (DO-41) axial leaded package with matte tin-plated leads compliant to J-STD-002 and JESD22-B102, and meets UL 94 V-0 flammability rating. The HE3 suffix confirms AEC-Q101 qualification and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11.1 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 12 V nominal systems. |
| VBR (min/max) | 12.4 V / 14.3 V at 1 mA - Confirmed breakdown threshold range; ensures reliable turn-on during transients while avoiding false triggering. |
| VC @ IPPM | 18.2 V at 22 A - Clamped voltage under 400 W 10/1000 µs surge; limits downstream IC stress to safe levels in automotive CAN/LIN lines. |
| IPPM | 22 A - Peak pulse current handling capacity; supports IEC 61000-4-5 Level 3 (1 Ω/2 Ω coupling) surge immunity testing. |
| PPPM | 400 W - Peak pulse power rating with 0.01 % duty cycle; enables repetitive transient suppression in motor drive feedback paths. |
| TJ max | +175 °C - Maximum junction temperature; supports under-hood automotive placement and high-ambient industrial environments. |
| Leakage (ID) | <1 µA at VWM - Ultra-low reverse leakage preserves signal integrity in high-impedance sensor inputs and battery-backed circuits. |
Pinout & Package
Package: DO-204AL (DO-41) axial-leaded, epoxy-molded case with matte tin-plated leads. Dimensions: 25.4 mm body length min., 5.2 mm max. diameter, 2.7 mm lead diameter. Complies with UL 94 V-0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (bi-directional) | Non-polarized transient shunt path | No cathode marking; terminals are functionally identical - enables symmetrical protection on AC-coupled or floating differential lines (e.g., RS-485, CAN bus). |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables <1 ns response time and stable VBR over lifetime - critical for protecting fast-edge microcontroller I/O against ESD and load dump. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock - required for engine control, ADAS sensor, and infotainment modules. |
| 400 W peak pulse power (10/1000 µs) | Withstands repeated ISO 7637-2 Pulse 1/2a/3a transients and IEC 61000-4-4 EFT bursts without degradation. |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes let-through energy during surges - reduces need for secondary filtering and extends lifetime of protected MOSFETs or transceivers. |

Use Scenario: Protecting PLC or RF (NB-IoT) communication pins in utility smart meters installed in electrically noisy substations. IC Role / Device Role / Timing Role: Bi-directional shunt element on meter's HPLC or LTE antenna feed line. Use Value: Withstands 2 kV ring wave (IEC 61000-4-5) surges while maintaining <1 µA leakage to avoid draining supercapacitor backup power. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | Same VWM (11 V), higher VC (19.9 V), SMC package (surface-mount), 600 W PPPM. | Requires PCB redesign for SMD layout; better suited for space-constrained consumer electronics vs. through-hole industrial modules. | Select SMBJ11CA when board area is limited and reflow assembly is used; verify thermal pad design for 600 W derating. |
| P6KE12CA | Higher VWM (12 V), same DO-41 package, lower PPPM (600 W but 1.5× larger 6.4×6.4 mm case), 20.1 V VC. | Less precise VWM margin for 12 V systems; larger footprint may conflict with existing DO-41 keepouts. | Choose P6KE12CA only if legacy P6KE footprint compatibility is mandatory and 12 V tolerance is acceptable. |
Compared with BZW04P11BHE3/54, SMBJ11CA offers higher surge rating in a compact SMD form but requires layout change, while P6KE12CA retains through-hole mounting but sacrifices VWM precision and thermal efficiency - BZW04P11BHE3/54 delivers optimal balance of AEC-Q101 reliability, tight 11.1 V standoff, and proven DO-41 manufacturability.

FAQ
What is the maximum clamping voltage of BZW04P11BHE3/54 under surge conditions?
The BZW04P11BHE3/54 has a maximum clamping voltage (VC) of 18.2 V at 22 A peak pulse current (10/1000 µs waveform). This value is measured per IEC 61000-4-5 test conditions and ensures downstream circuitry remains within safe voltage limits during standardized surge events. The clamping performance is guaranteed across the full operating temperature range (-55 °C to +175 °C).
Is BZW04P11BHE3/54 suitable for automotive applications?
Yes, BZW04P11BHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - including glass-passivated junction, DO-41 package with JESD201 Class 2 whisker resistance, and operation up to +175 °C - meets stringent requirements for engine control units, body electronics, and ADAS sensor modules. The HE3 suffix confirms full AEC-Q101 compliance per Vishay documentation.
How does the bi-directional configuration of BZW04P11BHE3/54 affect its circuit implementation?
The bi-directional configuration of BZW04P11BHE3/54 means it functions identically in both polarities with no cathode marking - ideal for protecting AC-coupled, differential, or floating signal lines like CAN, LIN, or RS-485. Unlike uni-directional TVS diodes, it eliminates polarity orientation errors during manual assembly and provides symmetrical clamping on both positive and negative transients without additional components.
What is the leakage current specification for BZW04P11BHE3/54 at its stand-off voltage?
BZW04P11BHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 11.1 V stand-off voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage preserves signal fidelity in high-impedance sensor interfaces and minimizes standby power loss in battery-powered smart meter designs - a key advantage over higher-leakage alternatives like P6KE series.
Can BZW04P11BHE3/54 be used in place of uni-directional TVS diodes in DC power rail protection?
No - BZW04P11BHE3/54 is strictly bi-directional and must not replace uni-directional TVS diodes in DC power rail applications where forward conduction must be blocked. In such cases, it would conduct continuously during normal operation. For DC rail protection, use uni-directional variants like BZW04P11HE3/54 (cathode-banded) or confirm circuit topology supports symmetrical clamping before substitution.
