Product details
Overview
P6KE16-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 16 V breakdown voltage (VBR min/max = 15.2–16.8 V), 13.6 V standoff voltage (VWM), 22.5 V clamping voltage at 26.7 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interface protection and industrial I/O port surge suppression.
For engineers reviewing the P6KE16-E3/54 datasheet, P6KE16-E3/54 pinout, P6KE16-E3/54 application, or P6KE16-E3/54 equivalent, key selection criteria include verified clamping performance under 26.7 A transient current, unidirectional polarity with cathode band marking, DO-204AC (DO-15) package compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a silicon avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response time and low incremental surge resistance. Its clamping behavior is defined by a maximum 22.5 V voltage across terminals when subjected to a 10/1000 µs 26.7 A surge, with thermal resistance RθJL = 20 °C/W enabling effective lead-based heat dissipation.
The P6KE16-E3/54 is rated for continuous power dissipation of 5.0 W on an infinite heatsink at TL = 75 °C and supports 100 A non-repetitive forward surge current (8.3 ms half-sine). Its operating junction temperature range spans –55 °C to +175 °C, and it exhibits a positive temperature coefficient of 0.086 %/°C for VBR, ensuring stable breakdown voltage drift with temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | DO-214AA package (SMB), 600 W rating, VBR = 16.7–18.5 V, VC = 26.0 V @ 23.1 A | Surface-mount alternative with higher clamping voltage and lower peak current handling | Select SMBJ16A when board space constraints require SMD mounting and 26.0 V clamping is acceptable for protected ICs |
| 1.5KE16A | DO-201AD package, identical VBR/VC specs but 1.5 kW peak power (10/1000 µs), larger footprint | Higher-power legacy through-hole option with same electrical behavior but greater surge margin | Choose 1.5KE16A where system-level surge testing exceeds 600 W requirements or legacy designs mandate DO-201AD form factor |
Compared with SMBJ16A and 1.5KE16A, the P6KE16-E3/54 delivers optimal balance of compact DO-15 through-hole packaging, AEC-Q101 qualification, and precise 22.5 V clamping-making it preferred for cost-sensitive, automotive-qualified, and space-constrained industrial power rail protection.

FAQ
What is the clamping voltage of the P6KE16-E3/54 under maximum surge conditions?
The P6KE16-E3/54 has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current of 26.7 A using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during transient events - a critical parameter for ensuring downstream 15 V-rated ICs remain within absolute maximum ratings. The P6KE16-E3/54 achieves this clamping performance consistently across its qualified operating temperature range.
Is the P6KE16-E3/54 suitable for automotive applications?
Yes, the P6KE16-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and sensor modules. Its construction uses glass-passivated junction technology, DO-204AC molding compliant with UL 94 V-0, and matte tin-plated leads meeting JESD 22-B102 solderability standards - all validated per AEC-Q101 stress test requirements. The P6KE16-E3/54 operates reliably from –55 °C to +175 °C, supporting under-hood thermal environments.
How does the P6KE16-E3/54 differ from bi-directional TVS diodes like P6KE16CA?
The P6KE16-E3/54 is unidirectional and features a cathode band marking, intended for DC line protection where polarity is fixed - such as 12 V or 24 V power rails. In contrast, P6KE16CA is bi-directional with no polarity marking and symmetric clamping in both directions, suited for AC signal lines or data buses like RS-485. The P6KE16-E3/54 specifies forward voltage (VF = 3.5 V at 50 A), while P6KE16CA does not - a key distinction affecting forward conduction behavior during fault conditions.
What is the standoff voltage rating for the P6KE16-E3/54, and why does it matter?
The P6KE16-E3/54 has a maximum working standoff voltage (VWM) of 13.6 V, meaning it remains in high-impedance state with ≤1.0 µA leakage current up to this DC or RMS voltage level. This rating ensures the device does not interfere with normal circuit operation - for example, it avoids false triggering on a nominal 12 V rail with ±10 % tolerance. Exceeding VWM risks premature conduction and increased power loss, so proper margin between system operating voltage and VWM is essential in P6KE16-E3/54 design-in.
Can the P6KE16-E3/54 be used in parallel for higher surge current handling?
No - the P6KE16-E3/54 is not characterized or recommended for parallel operation due to inherent parameter variation (e.g., VBR tolerance ±5 %) that causes current imbalance and potential thermal runaway. Vishay specifies single-device operation only; for higher surge capacity, select a higher-power TVS such as 1.5KE16A (1.5 kW) or verify layout-level current sharing with external ballast resistors - though this approach compromises clamping performance and is not supported in the P6KE16-E3/54 datasheet.
