Product details
Overview
P6KA16HE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection of sensitive electronics. It features a 14.4 V minimum breakdown voltage (VBR), 12.9 V standoff voltage (VWM), 600 W peak pulse power (10/1000 μs), 25.5 A peak pulse current (IPPM), and 23.5 V maximum clamping voltage (VC) - deployed in automotive power line and sensor interface protection.
For engineers reviewing the P6KA16HE3/54 datasheet, P6KA16HE3/54 pinout, P6KA16HE3/54 application, or P6KA16HE3/54 equivalent, key selection considerations include its AEC-Q101 qualification, 185 °C junction temperature rating, DO-204AC (DO-15) package, unidirectional polarity, and clamping performance under repetitive 10/1000 μs transients.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, leveraging passivated anisotropic rectifier technology to achieve fast response (<1 ns) and low incremental surge resistance. Its unidirectional configuration enables integration into DC-biased lines where reverse conduction must be blocked until clamping threshold is exceeded.
Rated for TJ = –65 °C to +185 °C and qualified per AEC-Q101, the P6KA16HE3/54 supports high-reliability automotive environments. It sustains 75 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits a +0.086 %/°C VBR temperature coefficient - critical for stable clamping across wide thermal operating ranges.
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 |
|---|---|---|---|
| SMAJ16A-E3/52 | Same VWM (13.6 V), higher VC (25.8 V), SMA package (surface-mount), 400 W PPPM | Requires PCB rework for SMT vs. through-hole; lower power rating limits use in load dump scenarios | Select for space-constrained consumer or industrial boards where 400 W suffices and SMT is preferred. |
| 1.5KE16A | Same VWM (13.6 V), identical DO-204AC package, but 1500 W PPPM and higher IPPM (65.2 A) | Higher clamping voltage (25.0 V) and no AEC-Q101 qualification - unsuitable for automotive safety-critical modules | Select for cost-sensitive industrial power supplies needing higher surge margin but no automotive qualification. |

FAQ
What is the maximum clamping voltage of the P6KA16HE3/54 under standard test conditions?
The P6KA16HE3/54 has a maximum clamping voltage (VC) of 23.5 V when subjected to its rated peak pulse current (IPPM) of 25.5 A using a 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events. The P6KA16HE3/54 maintains this clamping performance across its full operating temperature range due to its low VBR temperature coefficient of +0.086 %/°C.
Is the P6KA16HE3/54 suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the P6KA16HE3/54 is explicitly AEC-Q101 qualified, as confirmed in Vishay's official documentation (Document Number: 88368). It meets all required stress tests including high-temperature operating life, temperature cycling, and unbiased HAST. Its 185 °C maximum junction temperature rating and DO-204AC construction with matte tin-plated leads further support deployment in under-hood automotive modules such as engine control units and lighting drivers.
What is the standoff voltage (VWM) and why is it important for P6KA16HE3/54 system integration?
The P6KA16HE3/54 has a standoff voltage (VWM) of 12.9 V, meaning it remains in high-impedance state up to this reverse voltage level with leakage current ≤1.0 μA. This parameter is critical for ensuring the device does not interfere with normal 12 V automotive or industrial system operation while remaining ready to clamp transients above ~14.4 V (VBR min). Selecting a VWM correctly avoids false triggering and preserves signal integrity in always-on circuits.
Does the P6KA16HE3/54 have polarity markings, and how is its pinout configured?
Yes, the P6KA16HE3/54 uses a unidirectional configuration with polarity clearly marked: a colored band on the epoxy body denotes the cathode terminal. In circuit implementation, the cathode connects to the line being protected (e.g., 12 V rail), and the anode connects to ground. This arrangement ensures the device blocks normal forward current while conducting only during reverse overvoltage events - a requirement for DC-biased protection schemes.
How does the P6KA16HE3/54 compare to older 1.5KE-series TVS diodes in terms of thermal performance?
The P6KA16HE3/54 offers superior thermal performance versus legacy 1.5KE-series devices, with a maximum junction temperature (TJ) rating of +185 °C compared to +175 °C for most 1.5KE parts. Its optimized passivated junction design also delivers tighter VBR tolerance and lower dynamic impedance, resulting in more consistent clamping under repeated surges. Unlike many 1.5KE variants, the P6KA16HE3/54 is AEC-Q101 qualified - confirming its suitability for modern automotive thermal and reliability requirements.
