Product details
Overview
P6KE15AH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage clamping in power supply input stages and automotive ECU protection circuits. It features a 15V nominal breakdown voltage (VBR min/max: 14.3V–15.8V), 12.8V stand-off voltage (VWM), 29A peak surge current (IPP), and 21.2V maximum clamping voltage (VC) at rated surge - enabling robust protection of 12V/24V systems against ISO 7637-2 pulse 1/2a/5a transients.
For engineers reviewing the P6KE15AH datasheet, P6KE15AH pinout, P6KE15AH application, or P6KE15AH equivalent, this AEC-Q101 qualified DO-15 TVS offers verified clamping performance under 10/1000μs surges, low dynamic impedance (<0.7Ω typical), sub-1ps response time, and <1μA leakage above 10V - critical for high-reliability automotive and industrial front-end protection where leakage-induced bias drift or thermal runaway must be avoided.
Technical Context
The P6KE15AH implements a silicon avalanche junction structure optimized for fast, repeatable clamping during high-energy transients. Its unidirectional configuration provides asymmetric conduction: low forward voltage drop (~1.2V @ 100A) during surge conduction while blocking reverse voltage up to 12.8V in standby.
Thermal design relies on its DO-204AC (DO-15) package with pure tin-plated leads and 175°C max junction temperature. Derating begins above 25°C ambient per Fig.2, requiring PCB copper pad area ≥5×5 mm per lead for full 600W rating - essential for sustained surge handling in engine bay or power converter environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12.8 V - Maximum continuous reverse voltage before significant leakage; sets upper limit for system operating voltage margin. |
| VBR (min/max) | 14.3 V / 15.8 V - Breakdown occurs within this range at 1 mA test current; defines clamping onset tolerance for surge threshold setting. |
| VC @ IPP | 21.2 V @ 29 A - Clamped voltage during 10/1000μs surge; determines maximum stress imposed on downstream ICs like MCUs or gate drivers. |
| PPK | 600 W - Peak non-repetitive surge power handling; validates capability against IEC 61000-4-5 Level 4 (4kV) and ISO 7637-2 Pulse 5a. |
| IR @ VWM | <1 μA - Reverse leakage at stand-off voltage; ensures negligible standby current drain in battery-powered modules. |
| TJ max | 175 °C - Maximum junction temperature; supports operation in under-hood automotive locations without derating below -40°C to +125°C ambient. |
| Response time | <1.0 ps - Time from 0 V to VBR; enables clamping before transient energy couples into sensitive analog or digital circuitry. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking. Dimensions per JEDEC DO-15 standard: body diameter 2.54 mm ±0.25 mm, length 5.21 mm ±0.25 mm, lead diameter 0.61 mm ±0.05 mm.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ15A | Same DO-214AC package; 15V VBR (14.3–15.8V), 21.2V VC @ 29A, but rated for 400W only. | Lower surge rating limits use to lower-energy transients (e.g., ESD-only); not validated for ISO 7637-2 Pulse 5a. | Select when cost sensitivity outweighs automotive surge requirement and PCB space allows larger footprint. |
| ON Semiconductor 1.5KE15A | DO-201AD package; identical electrical specs (15V VBR, 21.2V VC), but 1.5kW surge rating and higher thermal mass. | Higher surge capacity suits industrial motor drives; larger package requires revised PCB layout and thermal relief. | Select when system-level surge testing exceeds 600W or extended thermal cycling (>1000 cycles) is required. |
Compared with SMAJ15A and 1.5KE15A, the P6KE15AH uniquely balances AEC-Q101 qualification, DO-15 compactness, and 600W surge capability - making it optimal for space-constrained automotive modules where certification and reliability are non-negotiable.

FAQ
What is the AEC-Q101 qualification status of P6KE15AH?
The P6KE15AH is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H", confirmed in the P6KE Series datasheet Version P2203 Section 4. This includes stress testing for temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - validating suitability for automotive powertrain and chassis applications.
How does P6KE15AH differ from the non-H variant P6KE15A?
The P6KE15AH differs from P6KE15A solely in AEC-Q101 qualification and associated process controls; electrical parameters (VBR, VC, IPP, VWM) and package (DO-15) are identical. The "H" suffix indicates additional screening and lot-level traceability required for automotive use, with no performance trade-offs.
Can P6KE15AH be used in bidirectional configurations?
No - P6KE15AH is unidirectional only, as indicated by its part number suffix and cathode-band marking. Bidirectional variants require "CA" suffix (e.g., P6KE15CA). Using P6KE15AH in reverse-biased mode risks permanent breakdown due to lack of symmetric avalanche structure.
What is the maximum allowable PCB trace length between P6KE15AH and protected IC?
To maintain sub-1ps effective response, PCB trace inductance must be minimized: recommended trace length ≤5 mm with 1.5 mm width and direct ground plane coupling. Longer traces add inductance that increases clamping voltage (ΔV = L·di/dt), potentially exceeding the 21.2V VC rating during fast transients.
Does P6KE15AH require derating at elevated ambient temperatures?
Yes - the P6KE15AH must be derated linearly above 25°C ambient per Fig.2 in the datasheet: at 75°C ambient, peak pulse power drops to ~450W. Full 600W rating requires thermal management via 5×5 mm copper pads per lead and airflow or conduction paths to maintain junction temperature ≤175°C.
