Product details
Overview
P6KE22CH 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 nominal breakdown voltage of 22 V, clamps transients to ≤31.9 V at 19 A peak surge current, and delivers sub-1 ps response time from 0 V to VBR. It is AEC-Q101 qualified and housed in a DO-204AC (DO-15) package for automotive-grade ESD and lightning surge immunity.
For engineers reviewing the P6KE22CH datasheet, P6KE22CH pinout, P6KE22CH application, or P6KE22CH equivalent, key selection criteria include its 22 V standoff rating (VWM = 17.8 V), low dynamic impedance, <1 μA leakage above 10 V, UL 94V-0 molding compound, and AEC-Q101 qualification - critical for automotive body electronics, industrial sensor interfaces, and 24 V rail protection where reliability under repetitive surge stress is mandatory.
Technical Context
The P6KE22CH operates as a unidirectional avalanche diode with a single-die DO-204AC construction, optimized for fast clamping of 10/1000 µs waveform surges up to 600 W. Its junction temperature range spans −55 °C to +175 °C, enabling deployment in under-hood automotive environments and high-ambient industrial controls.
It exhibits a temperature coefficient of VBR of 0.092 %/°C and maintains stable clamping performance across its full operating temperature range. The device's low reverse leakage (<1 µA at VWM) ensures minimal standby power loss in always-on systems such as CAN bus nodes and battery-backed sensors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 17.8 V - Maximum continuous DC or RMS voltage the device blocks without conduction; sets upper limit for protected circuit operating voltage. |
| VBR (Breakdown Voltage) | 19.8–24.2 V @ 1 mA - Voltage at which avalanche conduction begins; defines threshold for transient clamping activation. |
| VC @ IPP (Clamping Voltage) | 31.9 V @ 19 A - Maximum voltage seen by downstream circuit during 10/1000 µs surge; determines safe margin for IC input tolerance. |
| PPK (Peak Pulse Power) | 600 W - Surge energy handling capability per single 10/1000 µs pulse; supports IEC 61000-4-5 Level 3/4 compliance testing. |
| IR (Reverse Leakage) | <1 µA @ 17.8 V - Negligible quiescent current draw; avoids loading of high-impedance voltage references or battery-powered circuits. |
| TJMAX | +175 °C - Enables operation in engine control units, motor drives, and other high-temperature PCB locations without derating. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with tin-plated leads, RoHS/halogen-free, UL 94V-0 rated epoxy. |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking. Leads are pure tin-plated and solderable per J-STD-002. Polarity is unidirectional: cathode (banded end) connects to protected line; anode connects to ground or lower potential reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (non-banded end) | Reference node connection | Connected to system ground or lowest-potential return path; establishes clamping reference for transient energy diversion. |
| Cathode (banded end) | Protected line connection | Connected directly to the line being safeguarded (e.g., 24 V supply rail or CAN_H); conducts surge current to ground when VBR exceeded. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, lighting modules, and ADAS sensor interfaces per stress test requirements. |
| 600 W 10/1000 µs surge rating | Withstands repeated high-energy transients per ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 without degradation. |
| Sub-1 ps response time (0 V → VBR) | Clamps before sensitive logic or analog circuitry can be damaged by fast-rising ESD or switching spikes. |
| UL 94V-0 flammability rating | Self-extinguishing epoxy prevents fire propagation in enclosed automotive or industrial enclosures during fault conditions. |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and global environmental directives for sustainable manufacturing and end-of-life recycling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ22A | Same DO-214AC package; 22 V VWM, 35.5 V VC @ 17.1 A; higher clamping voltage than P6KE22CH (31.9 V). | Higher clamping reduces margin for 24 V systems with tight IC VIN max ratings (e.g., 36 V absolute max). | Select SMAJ22A only if board layout favors surface-mount and system VIN max ≥ 36 V. |
| ON Semiconductor 1.5KE22A | Same DO-204AC package; identical VWM (17.8 V), VBR (19.8–24.2 V), but lower PPK = 1500 W (1.5 kW) - not 600 W; note: 1.5KE series is 1500 W, not 600 W. | Higher surge rating suits infrequent high-energy events (e.g., lightning), but larger size and higher cost may be unnecessary for automotive load dump. | Choose 1.5KE22A only when legacy design requires 1500 W rating and DO-204AC compatibility; verify thermal derating at 175 °C. |
Compared with SMAJ22A and 1.5KE22A, the P6KE22CH offers the lowest clamping voltage (31.9 V) in a compact DO-15 package with AEC-Q101 validation - making it optimal for space-constrained, thermally demanding automotive 24 V systems where precise voltage limiting is critical.

FAQ
What is the maximum clamping voltage of the P6KE22CH at its rated surge current?
The P6KE22CH clamps to a maximum of 31.9 V at 19 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components see no more than 31.9 V during surge events - critical for protecting 3.3 V or 5 V logic interfaced via level shifters or isolated drivers in automotive systems using the P6KE22CH.
Is the P6KE22CH suitable for bidirectional transient protection?
No, the P6KE22CH is a unidirectional TVS diode, indicated by the "H" suffix (AEC-Q101 qualified) and absence of "CA" or "C" designation. It conducts only in reverse bias and must be installed with cathode toward the protected line. For bidirectional protection, select P6KE22CH's counterpart P6KE22C or P6KE22CA - both rated for symmetrical clamping in either polarity.
Does the P6KE22CH meet automotive qualification standards?
Yes, the P6KE22CH is explicitly AEC-Q101 qualified per the manufacturer's ordering code definition (the "H" suffix denotes AEC-Q101 compliance). It has passed stress tests including high-temperature operating life, temperature cycling, and ESD per AEC-Q101 Rev D, making it approved for use in automotive powertrain, chassis, and body electronics where reliability under thermal and electrical stress is mandated.
What is the junction-to-ambient thermal resistance (RθJA) of the P6KE22CH in standard mounting?
The P6KE22CH does not specify RθJA in its datasheet because thermal performance is defined via steady-state power dissipation (PD = 5 W at TA = 75 °C with 9.5 mm lead length) and junction temperature limits (TJ = −55 °C to +175 °C). Its DO-204AC package relies on PCB copper area and lead thermal mass rather than RθJA; design guidance recommends 5 × 5 mm copper pads per terminal for rated power handling.
How does the P6KE22CH compare to the P6KE22A in terms of electrical performance?
The P6KE22CH and P6KE22A share identical electrical specifications - VWM = 17.8 V, VBR = 19.8–24.2 V, VC = 30.6 V @ 20 A - but differ in qualification: P6KE22CH is AEC-Q101 qualified (H suffix), whereas P6KE22A is commercial-grade. Both use DO-204AC packaging and have the same surge rating (600 W), but only P6KE22CH is approved for automotive applications requiring AEC-Q101 validation.
