Product details
Overview
BZW04-7V0B-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 400 W peak pulse power (10/1000 μs), 7.79–8.61 V breakdown voltage at 10 mA test current, and 12.1 V maximum clamping voltage at 33.0 A peak pulse current - suitable for protecting I/O interfaces in automotive sensor modules.
For engineers reviewing the BZW04-7V0B-E3/54 datasheet, BZW04-7V0B-E3/54 pinout, BZW04-7V0B-E3/54 application, or BZW04-7V0B-E3/54 equivalent, key selection criteria include bidirectional clamping capability, 7.02 V stand-off voltage, AEC-Q101 qualification, and DO-41 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
This device operates symmetrically in both polarities, delivering identical clamping performance regardless of transient polarity. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance under repetitive 10/1000 μs surges at 0.01% duty cycle.
The BZW04-7V0B-E3/54 exhibits a temperature coefficient of VBR of +0.065 %/°C and maintains full functionality across -55 °C to +175 °C junction temperature range. It supports 200 μA max reverse leakage at 7.02 V stand-off voltage and withstands solder dip up to 275 °C for 10 s per JESD22-B106.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.02 V - maximum continuous reverse operating voltage before significant leakage begins |
| VBR min/max | 7.79 V / 8.61 V at 10 mA - guaranteed breakdown onset window for reliable clamping threshold setting |
| VC @ IPPM | 12.1 V at 33.0 A - clamped voltage during worst-case 400 W transient, limiting downstream stress |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform, enabling robust ESD and surge immunity |
| ID @ VWM | 200 μA - low leakage ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ max | +175 °C - extended thermal rating supports under-hood automotive and industrial ambient environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0CA | DO-214AA package (SMB), 7.0 V VWM, 1000 W PPPM, higher capacitance (~1500 pF) | Suitable for higher-power surge events but less space-efficient; not axial lead-compatible | Select SMBJ7.0CA only if board layout allows surface-mount rework and higher clamping energy is required. |
| P6KE7.0CA | DO-15 package, same VWM/VBR range, lower PPPM (600 W), slower response due to larger junction area | Legacy through-hole alternative with longer lead inductance; less effective for fast transients | Choose P6KE7.0CA only for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
Compared with SMBJ7.0CA and P6KE7.0CA, the BZW04-7V0B-E3/54 offers optimal balance of axial-mount compatibility, AEC-Q101 compliance, and 400 W surge capacity - making it the preferred choice for new automotive and industrial through-hole designs requiring validated reliability.

FAQ
What is the clamping voltage of BZW04-7V0B-E3/54 under peak surge conditions?
The BZW04-7V0B-E3/54 has a maximum clamping voltage (VC) of 12.1 V at 33.0 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The BZW04-7V0B-E3/54 maintains this clamping performance bidirectionally and across its full operating temperature range.
Is BZW04-7V0B-E3/54 qualified for automotive use?
Yes, BZW04-7V0B-E3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per JESD22 standards. The "HE3" variant (e.g., BZW04-7V0B-HE3/54) denotes full AEC-Q101 qualification, while the "E3" suffix indicates RoHS-compliant commercial grade. BZW04-7V0B-E3/54 itself carries the E3 suffix and meets commercial-grade specifications; for automotive deployment, confirm with Vishay documentation whether the specific reel lot is HE3-marked or certified to AEC-Q101.
What package type does BZW04-7V0B-E3/54 use and what are its mechanical dimensions?
BZW04-7V0B-E3/54 uses the DO-41 (DO-204AL) axial-leaded package with overall length of 25.4 mm minimum and lead diameter of 0.71–0.86 mm. The molded epoxy case meets UL 94 V-0 flammability rating, and leads are matte tin plated per J-STD-002. This package enables direct replacement of legacy 1N4xxx series diodes and supports wave or hand soldering up to 275 °C for 10 seconds.
How does the bidirectional design of BZW04-7V0B-E3/54 affect its circuit implementation?
The bidirectional design of BZW04-7V0B-E3/54 means it functions identically in both polarities - no cathode marking is present, and it clamps positive and negative transients with matched VBR and VC parameters. This simplifies layout on AC-coupled lines, differential buses (e.g., RS-485), or ungrounded sensor outputs where polarity reversal is possible. Unlike unidirectional TVS diodes, the BZW04-7V0B-E3/54 requires no orientation check during assembly.
What is the maximum reverse leakage current specified for BZW04-7V0B-E3/54 at its stand-off voltage?
The BZW04-7V0B-E3/54 specifies a maximum reverse leakage current (ID) of 200 μA at its 7.02 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage ensures minimal impact on high-impedance sensing circuits and battery-powered systems. Leakage increases with temperature but remains within acceptable limits up to +125 °C junction temperature, as characterized in Vishay's derating curves.
