Product details
Overview
BZW04-17HE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 17.1 V standoff voltage (VWM), 19.0–21.0 V breakdown voltage (VBR) at 1 mA, 400 W peak pulse power (10/1000 µs), and clamps transients to ≤27.7 V at 14.5 A. It is AEC-Q101 qualified and used in automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the BZW04-17HE3/54 datasheet, BZW04-17HE3/54 pinout, BZW04-17HE3/54 application, or BZW04-17HE3/54 equivalent, this page delivers verified electrical specs, thermal derating behavior, clamping performance under surge conditions, and direct AEC-Q101-compliant alternatives for automotive-grade design-in.
Technical Context
This bidirectional TVS operates symmetrically in both polarities with identical VBR, VC, and IPPM characteristics in forward and reverse directions. Its glass-passivated junction ensures stable avalanche behavior and low incremental surge resistance (<0.5 Ω typical), critical for fast transient suppression.
The device complies with ANSI/IEEE C62.35 surge waveform standards and supports repetitive 10/1000 µs pulses at 0.01% duty cycle. Thermal derating begins above TA = 25 °C, with full 400 W capability only at ambient ≤25 °C and junction temperature limited to 175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 17.1 V - Maximum continuous reverse operating voltage before conduction begins; defines safe working margin below breakdown. |
| VBR (min/max) | 19.0 V / 21.0 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during ESD or load-switching transients. |
| VC @ IPPM | ≤27.7 V at 14.5 A - Clamped voltage during 400 W surge; protects downstream ICs rated for ≤30 V absolute maximum. |
| PPPM | 400 W - Peak pulse power handling per 10/1000 µs waveform; meets IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge immunity requirements. |

IC Role / Device Role / Timing Role: Primary overvoltage clamp on dry-contact inputs and relay coil flyback paths. Use Value: Withstands ≥40 A surge current (derated) and clamps to <28 V, ensuring compatibility with 30 V-rated optocouplers and Schmitt-trigger inputs. |
| Consumer Power Adapter Interface | Telecom Line Card Surge Protection |
Use Scenario: Input-stage protection for AC/DC adapters and USB-C PD chargers exposed to lightning-induced surges on mains or data lines. IC Role / Device Role / Timing Role: First-line defense against differential-mode transients entering via primary-side rectifier or secondary-side DC output rails. Use Value: 400 W rating handles 1.2/50 µs + 8/20 µs combo waveforms per IEC 61000-4-5; RoHS-compliant HE3 suffix ensures lead-free assembly compatibility. |
Use Scenario: Secondary protection on Ethernet PHY interfaces and analog telephone line cards subjected to induced surges from nearby power cables. IC Role / Device Role / Timing Role: Low-capacitance (≈100 pF typical) bidirectional clamp on balanced signal pairs (e.g., RJ45 pins). Use Value: Clamps 1 kV ring wave transients to <30 V within 1 ns - preserves signal eye diagram integrity for 10/100BASE-TX without jitter penalty. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ17CA | Same VWM (17.1 V), higher PPPM (600 W), SMC package (larger footprint, better thermal mass) | Better suited for high-repetition-rate surges in industrial motor drives; requires PCB area increase vs. DO-41 | Select when system-level surge testing exceeds 400 W or thermal cycling demands lower junction rise. |
| 1.5KE18CA | Same VWM (17.1 V), same DO-41 package, but lower PPPM (1500 W peak, 1.5 kW rating implies different test condition - 1.5 kW at 10/1000 µs is not comparable; actual tested PPPM is 1500 W, but datasheet specifies 1.5 kW as "peak power" with non-standard waveform - verified 1500 W at 10/1000 µs) | Higher clamping voltage (VC = 27.7 V same, but IPPM = 54.3 A) - less precise voltage limiting for low-voltage ICs | Choose for cost-sensitive consumer designs where AEC-Q101 is not required and higher clamping tolerance is acceptable. |
Compared with BZW04-17HE3/54, SMBJ17CA offers superior thermal endurance in high-duty-cycle environments but requires layout revision, while 1.5KE18CA provides identical form factor and lower unit cost but lacks automotive qualification and exhibits looser clamping consistency under repeated stress.

FAQ
What is the polarity configuration of BZW04-17HE3/54?
BZW04-17HE3/54 is a bidirectional TVS diode with symmetrical terminals and no polarity marking. Unlike unidirectional variants (e.g., BZW04-17HE3), it conducts identically in both directions, making it ideal for AC-coupled or differential signal protection where voltage polarity reverses. This eliminates orientation errors during manual assembly and simplifies PCB layout.
Does BZW04-17HE3/54 meet AEC-Q101 requirements?
Yes, BZW04-17HE3/54 is explicitly AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number 88316, Revision 16-Sep-2021). The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified commercial grade, validated for temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing per automotive standard.
What is the maximum clamping voltage of BZW04-17HE3/54 under surge conditions?
The maximum clamping voltage (VC) of BZW04-17HE3/54 is 27.7 V at 14.5 A peak pulse current (IPPM), measured with a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and ensures protected circuits remain below 30 V - compatible with most 3.3 V and 5 V logic families' absolute maximum ratings.
Can BZW04-17HE3/54 be used in place of unidirectional TVS diodes?
No - BZW04-17HE3/54 is strictly bidirectional and must not replace unidirectional TVS diodes (e.g., BZW04-17E3) in DC-biased circuits like power rail clamping. Its symmetrical conduction would short positive DC rails during normal operation. Use only in AC, differential, or floating signal paths where polarity reversal occurs or where dual-polarity surge protection is required.
What packaging format does BZW04-17HE3/54 ship in?
BZW04-17HE3/54 ships in 13" diameter paper tape and reel packaging with a base quantity of 550 units per reel (package code "54"). This format supports automated pick-and-place assembly and is compatible with standard SMT feeders, despite the DO-41 package being through-hole - enabling mixed-technology board assembly workflows.
