Product details
Overview
P6KE24H from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 24V nominal breakdown voltage (VBR min/max: 21.6V–26.4V), 19.4V stand-off voltage (VWM), 34.7V maximum clamping voltage at 18A peak surge current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE24H datasheet, P6KE24H pinout, P6KE24H application, or P6KE24H equivalent, key selection criteria include clamping performance under 10/1000μs surges, low leakage (<1μA at VWM), fast response (<1.0ps), DO-15 package compatibility, and AEC-Q101 compliance for harsh-environment deployment.
Technical Context
The P6KE24H operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its breakdown threshold to shunt transient energy to ground. Its low dynamic impedance ensures stable clamping during 600W 10/1000μs pulses, with junction temperature rated up to +175°C and storage range from –55°C to +175°C.
Designed for single-die configuration in DO-204AC (DO-15) packaging, it delivers <1μA reverse leakage above 10V and exhibits a VBR temperature coefficient of 0.094%/°C - enabling predictable voltage drift across operating temperatures without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 19.4 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below breakdown |
| VBR (min/max) | 21.6 V / 26.4 V - Measured at 1 mA test current; ensures reliable turn-on within defined tolerance band |
| VC @ IPP | 34.7 V @ 18 A - Clamped voltage during 10/1000μs surge; determines protected circuit's maximum stress level |
| PPK | 600 W - Peak pulse power handling per 10/1000μs waveform; defines transient energy absorption capability |
| IR @ VWM | <1 μA - Reverse leakage at rated stand-off voltage; minimizes standby power loss and signal distortion |
| TJ max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial environments |
| Package | DO-204AC (DO-15) - Standard axial-leaded package with tin-plated leads; compatible with through-hole reflow and wave soldering |
Pinout & Package
DO-204AC (DO-15) package with axial leads: cathode indicated by band marking; anode and cathode terminals define unidirectional conduction path. Leads are pure tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry / Surge return path | Connected to protected line's ground or low-side reference; completes clamping loop during transient |
| Cathode (banded end) | Reverse-biased terminal / Clamping node | Connected to protected line (e.g., 24V rail); conducts avalanche current when VIN > VBR |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | 600W rating, DO-214AA (SMB) package, bidirectional configuration, VWM = 20.5V, VC = 38.9V @ 15.4A | Surface-mount footprint; higher clamping voltage reduces margin for 24V systems with tight headroom | Select SMBJ24A only if board space constraints require SMD mounting and clamping headroom ≥14.9V is acceptable |
| 1.5KE24A | 600W rating, DO-201AD package, unidirectional, VWM = 20.5V, VC = 36.0V @ 16.7A, no AEC-Q101 qualification | Larger DO-201AD body; lacks automotive qualification but offers slightly lower clamping than P6KE24H | Choose 1.5KE24A for cost-sensitive industrial designs where AEC-Q101 is not mandated and PCB layout accommodates larger lead spacing |
Compared with SMBJ24A and 1.5KE24A, P6KE24H uniquely combines AEC-Q101 qualification, DO-15 through-hole compatibility, and the lowest clamping voltage (34.7V) among 24V 600W TVS diodes - making it optimal for automotive and high-reliability 24V rail protection where mechanical robustness and voltage margin are critical.

FAQ
What is the polarity configuration of the P6KE24H?
The P6KE24H is a unidirectional transient voltage suppressor diode with cathode identified by a band marking on the DO-15 package. It conducts in reverse bias during overvoltage events and blocks forward current like a standard rectifier diode. This configuration makes P6KE24H suitable for DC rail protection where polarity is fixed and reverse surge energy must be shunted to ground.
Does the P6KE24H meet automotive qualification standards?
Yes, the P6KE24H is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H", confirming compliance with stress tests for temperature cycling, humidity, mechanical shock, and high-temperature operating life. This qualification validates P6KE24H for use in engine compartments, transmission control units, and other automotive subsystems requiring extended reliability under thermal and vibration stress.
What is the maximum clamping voltage of the P6KE24H under surge conditions?
The P6KE24H has a maximum clamping voltage (VC) of 34.7 V at 18 A peak pulse current (IPP) under the standardized 10/1000 μs double-exponential surge waveform. This value is guaranteed across the full operating temperature range and represents the highest voltage seen across the device during worst-case transient events, directly defining protection headroom for downstream 24V-rated components.
How does the P6KE24H compare to the P6KE24A variant?
The P6KE24H shares identical electrical specifications with P6KE24A - including VBR (22.8–25.2 V), VWM (20.5 V), and VC (33.2 V) - but adds AEC-Q101 qualification and uses enhanced process controls for automotive applications. Unlike P6KE24A, the P6KE24H undergoes additional screening for temperature cycling and high-temperature reverse bias life testing, making it the preferred choice for mission-critical automotive deployments.
What packaging options are available for the P6KE24H?
The P6KE24H is supplied in DO-204AC (DO-15) package with pure tin-plated leads, offered in 3,500-piece tape-and-reel format (ordering code P6KE24HH) and 1,500-piece ammo box format (P6KE24HA0G). Both variants comply with J-STD-002 for solderability and JEDEC JESD201 Class 2 for whisker resistance, supporting automated through-hole assembly and manual rework.
