Product details
Overview
P6KE15H from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in power supply inputs, automotive electronics, and industrial control interfaces. It features a 15V nominal breakdown voltage (VBR min/max: 13.5V–16.5V), 12.1V stand-off voltage (VWM), 28A peak surge current (IPP), and clamps to ≤22.0V at rated surge - enabling robust ESD and lightning-induced transient suppression in 24V DC systems.
For engineers reviewing the P6KE15H datasheet, P6KE15H pinout, P6KE15H application, or P6KE15H equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) axial package, low dynamic impedance, sub-1ps response time from 0V to VBR, and compliance with IEC 61000-4-2/4-4/4-5 immunity standards for automotive and industrial end equipment.
Technical Context
The P6KE15H operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its 13.5V minimum breakdown threshold. Its clamping action limits transient energy to ≤22.0V at 28A (10/1000μs waveform), delivering 600W peak pulse power dissipation without thermal runaway under defined derating conditions up to 175°C junction temperature.
It exhibits <1μA maximum reverse leakage at 12.1V (VWM), 0.084%/°C temperature coefficient of VBR, and meets UL 94V-0 flammability rating in its molded DO-204AC case. The device is not bidirectional - cathode band marking defines polarity, and forward conduction is limited to 100A non-repetitive surge (8.3ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 12.1 V - Maximum continuous reverse operating voltage before significant leakage; sets safe DC bias margin below breakdown. |
| VBR (min/max) | 13.5 V / 16.5 V - Measured at 1 mA test current; defines guaranteed avalanche initiation range for design margining. |
| VC @ IPP | 22.0 V @ 28 A - Clamped voltage during 10/1000μs surge; determines maximum stress imposed on downstream circuitry. |
| PPK | 600 W - Peak pulse power handling per single 10/1000μs transient; enables protection against IEC 61000-4-5 Level 4 surges. |
| IR @ VWM | <1 μA - Reverse leakage at stand-off voltage; ensures minimal quiescent power loss and signal integrity in high-impedance nodes. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments. |
| Package | DO-204AC (DO-15) - Axial-leaded, RoHS-compliant, halogen-free package with tin-plated leads; compatible with wave soldering per J-STD-002. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with cathode band marking for unidirectional polarity. Dimensions conform to JEDEC DO-15 standard; weight ≈0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Low-side reference node | Connected to system ground or low-voltage rail; completes clamping path during reverse transient. |
| Cathode (banded end) | High-side transient sink | Connected to protected line (e.g., 24V input); conducts avalanche current to ground when VLINE > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, body electronics, and ADAS power rails. |
| 600W surge capability | Withstands single 10/1000μs transients up to 28A without degradation - meets IEC 61000-4-5 surge immunity requirements for industrial PLCs and motor drives. |
| Fast response time | <1.0 ps from 0V to VBR - clamps ESD events before sensitive ICs experience overstress, critical for USB, CAN, and sensor interface protection. |
| Low dynamic impedance | Enables tight clamping ratio (VC/VBR ≈ 1.63) - minimizes voltage overshoot across protected ICs during fast-rising transients. |
| UL recognition | UL File #E-326243 - certifies safety compliance for end-equipment approvals in North America and globally harmonized markets. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A (Bourns) | Same 15V VBR range but SMB package (SMD); 600W rating; slightly higher VC = 24.4V @ 24.7A. | Requires PCB rework for surface-mount layout; better for space-constrained designs but lacks axial lead mechanical robustness. | Select SMBJ15A only if board real estate is constrained and wave-solder compatibility is not required. |
| 1.5KE15A (ON Semiconductor) | Identical DO-15 package and 15V rating; same 600W rating; VC = 22.5V @ 27.3A; no AEC-Q101 qualification. | Valid for industrial use but not automotive qualified; lower cost where automotive reliability validation is unnecessary. | Choose 1.5KE15A for cost-sensitive industrial applications where AEC-Q101 is not mandated. |
Compared with SMBJ15A and 1.5KE15A, the P6KE15H provides AEC-Q101 qualification in an axial DO-15 package with tighter clamping (22.0V) and lower leakage (<1μA), making it optimal for automotive front-end power protection where mechanical durability and qualification traceability are mandatory.

FAQ
What is the polarity configuration of the P6KE15H?
The P6KE15H is a unidirectional TVS diode with clearly marked cathode band. It conducts only during reverse-biased transients - the banded end connects to the protected line (e.g., 24V input), and the unmarked end connects to ground. It does not function as a bidirectional device; using it in reverse orientation will prevent clamping.
Does the P6KE15H meet AEC-Q101 requirements?
Yes, the "H" suffix in P6KE15H explicitly denotes AEC-Q101 qualification per the manufacturer's ordering code definition. This includes stress testing for temperature cycling, high-temperature reverse bias, and ESD robustness - confirming suitability for automotive power modules, body control units, and infotainment power supplies.
What is the maximum clamping voltage of the P6KE15H under surge conditions?
The P6KE15H clamps to a maximum of 22.0V at 28A peak pulse current (10/1000μs waveform). This value is guaranteed across temperature and process variation, and defines the upper voltage limit imposed on downstream circuitry during standardized surge events per IEC 61000-4-5.
Can the P6KE15H be used in bidirectional applications?
No - the P6KE15H is strictly unidirectional. For bidirectional protection, TSC offers P6KE15CA (with "CA" suffix), which uses dual-die construction and symmetrical breakdown in both directions. Using P6KE15H in bidirectional mode risks failure during positive transients on the anode side.
What is the thermal derating behavior of the P6KE15H above 25°C ambient?
The P6KE15H follows a linear derating curve per Figure 2 in the datasheet: peak pulse power drops from 600W at 25°C to zero at 175°C junction temperature. At 75°C ambient, the device must be mounted on 5×5 mm copper pads per terminal to sustain 5W steady-state dissipation - critical for high-temperature under-hood placement.
