Product details
Overview
P6KE24AH 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 24V nominal breakdown voltage (VBR min/max: 22.8V–25.2V), 20.5V stand-off voltage (VWM), clamps to ≤33.2V at 19A peak surge current, and delivers sub-nanosecond response (<1.0ps) for ESD and lightning-induced transients in automotive body electronics.
For engineers reviewing the P6KE24AH datasheet, P6KE24AH pinout, P6KE24AH application, or P6KE24AH equivalent, key selection criteria include its AEC-Q101 qualification, DO-15 package compatibility with high-reliability PCB layouts, 175°C junction rating for under-hood environments, and verified clamping performance under 10/1000μs surge waveforms per IEC 61000-4-5.
Technical Context
The P6KE24AH operates as a silicon avalanche diode with unidirectional polarity, activated only during reverse-biased overvoltage events. Its low dynamic impedance ensures stable clamping across surge currents up to 19A, while the <1μA leakage at 20.5V supports low-power system standby integrity.
Thermal design relies on its 175°C maximum junction temperature and derating curve (Fig.2), enabling sustained operation at 75°C ambient when mounted on 5×5 mm copper pads. The device meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min–max) | 22.8V–25.2V - Ensures reliable turn-on above 20.5V operating rail without false triggering |
| VWM | 20.5V - Maximum continuous reverse voltage before leakage exceeds 1μA; defines safe DC operating margin |
| VC @ IPP | ≤33.2V @ 19A - Clamping voltage limits downstream IC stress during 10/1000μs surges (IEC 61000-4-5 Level 3) |
| PPK | 600W - Peak pulse power handling capability for single-event transients; not repetitive |
| TJ max | +175°C - Enables placement near heat sources (e.g., engine control units) without thermal shutdown |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with tin-plated leads compliant to J-STD-002 solderability |
| AEC-Q101 | Qualified - Validated for automotive applications including passenger compartment and chassis modules |
Pinout & Package
DO-204AC (DO-15) package with axial leads: Cathode indicated by band-marked end; anode is unmarked lead. Leads are pure tin-plated and solderable per J-STD-002. Weight: 0.400g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | Forward conduction path / Ground reference | Connected to system ground or low-side return; carries surge current to earth during clamping |
| Cathode (banded lead) | Reverse-biased avalanche node | Connected to protected line (e.g., 24V supply); initiates clamping when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, mechanical shock, and humidity testing per standard |
| Clamping voltage stability | VC ≤33.2V at 19A ensures protected ICs see <33.2V even under worst-case 10/1000μs surge |
| Ultra-fast response | <1.0ps rise time from 0V to VBR enables suppression of ESD events before logic thresholds are breached |
| Low leakage current | <1μA at 20.5V minimizes standby power loss in battery-powered systems like telematics modules |
| UL recognition | File #E-326243 confirms compliance with UL 1449 for transient protection devices |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | DO-214AA package (SMB), 600W rating, VBR = 26.7–29.5V, VC = 38.9V @ 15.4A | Surface-mount alternative with higher clamping voltage and lower surge current tolerance | Choose SMBJ24A for space-constrained PCBs where reflow assembly is required and 38.9V clamping is acceptable |
| 1.5KE24A | DO-201AD package, 1500W rating, VBR = 22.8–25.2V, VC = 36.0V @ 41.7A | Higher-power through-hole option with identical VBR but larger footprint and higher clamping | Choose 1.5KE24A when system-level surge requirements exceed 600W (e.g., ISO 7637-2 Pulse 5a) |
Compared with SMBJ24A and 1.5KE24A, the P6KE24AH offers optimal balance of AEC-Q101 qualification, DO-15 manufacturability, and precise 33.2V clamping-making it preferred for cost-sensitive, high-volume automotive body electronics where leaded reliability and thermal robustness are critical.

FAQ
What is the maximum clamping voltage of the P6KE24AH under surge conditions?
The P6KE24AH clamps to a maximum of 33.2V when subjected to its rated 19A peak surge current (IPP) under the standard 10/1000μs waveform. This value is guaranteed across temperature and lifetime, ensuring downstream ICs remain within safe operating voltage limits during transient events.
Is the P6KE24AH suitable for automotive applications?
Yes, the P6KE24AH is AEC-Q101 qualified (as indicated by the "H" suffix), having passed stress tests for temperature cycling, mechanical shock, and humidity resistance required for automotive electronic modules including body control units and lighting systems.
How does the P6KE24AH differ from the non-AEC-Q101 P6KE24A variant?
The P6KE24AH adds full AEC-Q101 qualification-including extended temperature cycling, board flex, and high-temperature reverse bias testing-while retaining identical electrical parameters (VBR, VWM, VC) and DO-15 packaging as the P6KE24A. The "H" suffix denotes this enhanced reliability grade.
What is the leakage current specification for the P6KE24AH at its stand-off voltage?
The P6KE24AH exhibits a maximum reverse leakage current of 1μA at its 20.5V stand-off voltage (VWM), measured at 25°C. This low leakage supports energy-efficient operation in always-on automotive subsystems such as door module controllers and sensor interfaces.
Can the P6KE24AH be used in bidirectional configurations?
No, the P6KE24AH is unidirectional only, as confirmed by its part number suffix "H" (not "CA" or "C") and cathode-band marking. For bidirectional protection, select P6KE24CA or equivalent variants explicitly rated for symmetrical clamping in both polarities.
