Product details
Overview
P6KE15A A0G from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 15V nominal breakdown voltage (VBR min/max = 14.3V/15.8V), 12.8V stand-off voltage (VWM), 21.2V clamping voltage at 29A peak surge current, and operates within -55°C to +175°C junction temperature range. It is commonly used in automotive body electronics and industrial power supply input stages.
For engineers reviewing the P6KE15A A0G datasheet, P6KE15A A0G pinout, P6KE15A A0G application, or P6KE15A A0G equivalent, key selection criteria include clamping performance under 10/1000μs surge, low leakage (<1μA @ 12.8V), AEC-Q101 qualification eligibility, DO-15 mechanical compatibility, and thermal derating behavior above 25°C ambient.
Technical Context
The P6KE15A A0G employs a planar passivated silicon junction optimized for fast transient response (<1.0ps rise time from 0V to VBR) and low dynamic impedance. Its unidirectional configuration provides asymmetric conduction-low forward voltage drop during normal operation and rapid avalanche clamping during reverse overvoltage events.
It is rated for non-repetitive 600W peak pulse power at 10/1000μs waveform, with thermal derating beginning at TA > 25°C per Fig.2 and maximum junction temperature limited to 175°C. The device uses pure tin-plated leads compliant with J-STD-002 and passes JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 15 V - defines the approximate DC operating voltage threshold where clamping initiates |
| Breakdown Voltage VBR | 14.3–15.8 V @ 1 mA - guaranteed avalanche onset range under standardized test conditions |
| Stand-Off Voltage VWM | 12.8 V - maximum continuous reverse voltage before significant leakage occurs |
| Clamping Voltage VC | 21.2 V @ 29 A IPP - peak voltage seen across device during 10/1000μs surge, limiting downstream stress |
| Peak Pulse Power PPK | 600 W - energy-handling capability for single transient events per IEC 61000-4-5 |
| Junction Temperature Range | -55°C to +175°C - enables use in under-hood automotive and high-temp industrial environments |
| Leakage Current ID | <1 μA @ 12.8 V - ensures minimal standby power loss and signal integrity in high-impedance circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ15A | Same DO-214AC package; slightly higher clamping voltage (23.2V @ 27.5A); identical 600W rating and 15V nominal | Designed for surface-mount assembly; requires PCB rework vs. through-hole DO-15 of P6KE15A A0G | Select for automated SMT production where board space and assembly efficiency outweigh through-hole serviceability needs. |
| ON Semiconductor 1.5KE15A | Same DO-204AC (DO-15) package; identical VBR (14.3–15.8V), VWM (12.8V), and VC (21.2V); 1.5kW rating (vs. 600W) indicates higher single-pulse tolerance but larger thermal mass | Higher surge rating suits infrequent high-energy events (e.g., lightning-induced surges); not optimized for repetitive transients | Choose when system-level testing reveals need for >600W margin, and physical size constraints allow same DO-15 footprint. |
Compared with SMAJ15A and 1.5KE15A, the P6KE15A A0G offers optimal balance of through-hole manufacturability, precise 21.2V clamping, and verified AEC-Q101 qualification path - making it preferred for cost-sensitive, high-volume automotive and industrial designs requiring proven reliability in DO-15 form factor.

FAQ
What is the clamping voltage of P6KE15A A0G and how is it measured?
The P6KE15A A0G has a maximum clamping voltage (VC) of 21.2 V, measured at a peak pulse current (IPP) of 29 A using the standardized 10/1000 μs double-exponential surge waveform. This value represents the highest voltage that will appear across the device during such a transient event, directly limiting stress on downstream components. The test condition is defined in ANSI/IEEE C62.35 and confirmed in Taiwan Semiconductor's P2203 datasheet revision.
Is P6KE15A A0G AEC-Q101 qualified?
The P6KE15A A0G itself is not explicitly marked as AEC-Q101 qualified in the provided documentation; however, the P6KE series offers AEC-Q101 variants denoted by an "H" suffix (e.g., P6KE15AH). The "A0G" suffix indicates ammo box packaging (1,500 units) and green compound, not qualification status. Engineers requiring automotive-grade assurance should specify P6KE15AH instead of P6KE15A A0G for AEC-Q101-compliant designs.
What does the "A" suffix mean in P6KE15A A0G?
In the P6KE15A A0G designation, the "A" denotes the tighter tolerance version of the P6KE15 base part: it specifies a narrower breakdown voltage range of 14.3–15.8 V (vs. 13.5–16.5 V for P6KE15), resulting in more consistent clamping behavior across production lots. This improves design predictability in precision protection applications where variation in VBR could affect system-level surge margin.
Can P6KE15A A0G be used in bidirectional configurations?
No - P6KE15A A0G is a unidirectional TVS diode, intended only for DC line protection with defined polarity (cathode toward higher potential). Bidirectional operation requires a symmetrical device such as P6KE15CA, which has identical breakdown characteristics in both directions. Using P6KE15A A0G in reverse-biased AC or floating applications risks permanent failure due to forward conduction during negative half-cycles.
What is the thermal derating behavior of P6KE15A A0G above 25°C ambient?
P6KE15A A0G follows a linear thermal derating curve starting at 25°C ambient: its 600W peak pulse power rating decreases proportionally as temperature rises, reaching zero at 175°C junction temperature. Per Fig.2 in the P2203 datasheet, at 75°C ambient (with 9.5mm lead length), the device is rated for 5W steady-state dissipation - meaning sustained power must remain well below this level unless heatsinking is applied.
