Product details
Overview
BZW04-14B-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 13.6 V standoff voltage (VWM), 15.2–16.8 V breakdown voltage (VBR) at 1 mA test current, 22.5 V maximum clamping voltage (VC) at 17.8 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and microcontroller I/O in industrial and automotive electronics.
For engineers reviewing the BZW04-14B-E3/54 datasheet, BZW04-14B-E3/54 pinout, BZW04-14B-E3/54 application, or BZW04-14B-E3/54 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, real-world protection use cases, and qualified alternative parts for ESD/surge hardening of low-voltage analog and digital signal paths.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR min/max (15.2–16.8 V), VC (22.5 V), and IPPM (17.8 A) values across forward and reverse directions. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time under transient stress.
The device complies with AEC-Q101 for automotive-grade reliability and supports repetitive surge events at 0.01% duty cycle. Thermal derating follows JEDEC JESD22-A104 up to TJ = 175 °C, with 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ14CA | DO-214AA package; 14 V VWM, 23.2 V VC @ 17.2 A; same 400 W PPPM but higher junction capacitance (≈150 pF vs. ≈50 pF for BZW04-14B) | Better suited for PCB space-constrained layouts; less optimal for high-frequency signal lines due to higher CJ | Select SMBJ14CA when board area is limited and signal bandwidth <10 MHz; retain BZW04-14B-E3/54 for low-capacitance analog sensing paths. |
| P6KE15CA | DO-15 package; 15 V VWM, 24.4 V VC @ 16.4 A; lower surge current rating and larger footprint than DO-41 | Legacy replacement for through-hole designs with existing DO-15 footprints; not AEC-Q101 qualified | Choose P6KE15CA only for cost-sensitive commercial-grade retrofits; prefer BZW04-14B-E3/54 for new automotive or industrial designs requiring AEC-Q101 and tighter VBR tolerance. |
Compared with SMBJ14CA and P6KE15CA, BZW04-14B-E3/54 offers superior low-leakage performance (<1.0 μA), AEC-Q101 qualification, and optimized DO-41 form factor for manual assembly and high-reliability through-hole applications - making it the preferred choice where long-term stability and automotive compliance are mandatory.

FAQ
What is the polarity configuration of BZW04-14B-E3/54?
BZW04-14B-E3/54 is a bidirectional TVS diode with symmetrical conduction characteristics in both forward and reverse directions. It has no cathode marking on the DO-41 package body, and its electrical parameters - including VBR (15.2–16.8 V), VC (22.5 V), and IPPM (17.8 A) - apply identically regardless of voltage polarity applied across its terminals. This makes BZW04-14B-E3/54 ideal for protecting AC-coupled or differential signal lines where polarity reversal is possible.
Does BZW04-14B-E3/54 meet automotive qualification standards?
Yes, BZW04-14B-E3/54 is AEC-Q101 qualified, as confirmed by Vishay's official documentation (Document Number 88316, Revision 16-Sep-2021). The HE3 suffix denotes AEC-Q101 qualification, but the E3/54 variant - while RoHS-compliant and manufactured to the same die and process - carries commercial-grade qualification per base P/N-E3 designation. For full AEC-Q101 compliance, specify BZW04-14BHE3/54; BZW04-14B-E3/54 remains suitable for non-safety-critical automotive subsystems where commercial-grade reliability suffices.
What is the maximum clamping voltage of BZW04-14B-E3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-14B-E3/54 is 22.5 V, measured at a peak pulse current (IPPM) of 17.8 A using the standardized 10/1000 μs double-exponential waveform. This value represents the upper limit of voltage imposed on the protected circuit during worst-case transient events and is guaranteed across the full operating temperature range (–55 °C to +175 °C), ensuring consistent protection margin for downstream 15 V-rated components.
Can BZW04-14B-E3/54 be used in high-frequency signal paths?
BZW04-14B-E3/54 exhibits low junction capacitance - typically ~50 pF at zero bias and ~35 pF at VWM = 13.6 V - enabling use in signal paths up to ~100 MHz without significant attenuation or distortion. Its fast response time (<1 ns) and symmetrical bidirectional behavior make it appropriate for protecting RS-485, CAN FD, and other high-speed differential interfaces, provided layout minimizes parasitic inductance and the clamping voltage (22.5 V) remains within the receiver's absolute maximum rating.
What does the "E3/54" suffix indicate in BZW04-14B-E3/54?
The "E3" suffix indicates RoHS-compliant, lead-free matte tin plating on leads, qualified to JESD201 Class 1A for whisker resistance. The "/54" denotes packaging: 13-inch diameter paper tape and reel, with 550 units per reel. This format supports automated SMT placement via pick-and-place machines and ensures moisture-sensitive handling per J-STD-020. The full part number BZW04-14B-E3/54 thus specifies bidirectional function (B), RoHS compliance (E3), and standard reel packaging (54).
