Product details
Overview
P6KE22CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 22 V breakdown voltage (VBR min/max = 20.9–23.1 V), 18.8 V stand-off voltage (VWM), 30.6 V maximum clamping voltage at 19.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs and sensor interfaces in automotive ECUs.
For engineers reviewing the P6KE22CAHE3/54 datasheet, P6KE22CAHE3/54 pinout, P6KE22CAHE3/54 application, or P6KE22CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, and verified 175 °C junction temperature rating for under-hood automotive use.
Technical Context
This device operates as a voltage-clamped shunt protector: during transient overvoltage events exceeding VWM (18.8 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its bidirectional symmetry ensures identical clamping behavior for positive and negative polarity transients.
It delivers 600 W peak pulse power handling per 10/1000 μs waveform at TA = 25 °C, with thermal derating above 25 °C per Fig. 2 and junction-to-lead thermal resistance of 20 °C/W. The glass-passivated junction enables fast response time (<1 ns) and stable leakage performance (≤1.0 μA at VWM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 20.9 V / 23.1 V - guaranteed avalanche onset range at 1.0 mA test current; defines minimum overvoltage threshold before clamping initiates |
| VWM | 18.8 V - maximum continuous reverse operating voltage; system signals must stay below this to avoid leakage or premature conduction |
| VC @ IPPM | 30.6 V at 19.6 A - worst-case clamped voltage seen by protected IC during full-rated 600 W transient; determines voltage stress on downstream components |
| PPPM | 600 W - peak transient energy absorption capacity with 10/1000 μs waveform; validates suitability for ISO 7637-2 Pulse 1/2/5a/b automotive transients |
| IPPM | 19.6 A - maximum non-repetitive surge current the device sustains without failure; sets minimum fuse/circuit breaker coordination point |
| TJ max | +175 °C - maximum junction temperature rating; enables placement near heat sources in engine control modules with no derating penalty |
| Qualification | AEC-Q101 qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness per JEDEC standards |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; no polarity marking - symmetric bidirectional construction eliminates cathode/anode orientation concerns during PCB placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path terminal | Either end conducts identically during positive or negative overvoltage events; no orientation required on board |
| Case (body) | Non-electrical mechanical interface | Plastic encapsulation provides UL 94 V-0 flammability rating and mechanical protection; no thermal or electrical connection |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables <1 ns response time and stable leakage (<1.0 μA at VWM) across -55 °C to +175 °C operating range |
| 600 W peak pulse power (10/1000 μs) | Validated for automotive load-dump and inductive switching transients per ISO 7637-2 without degradation |
| AEC-Q101 qualification | Confirms reliability for automotive powertrain and chassis applications requiring zero latent field failures |
| DO-15 package with JESD 22-B106 solderability | Supports wave and reflow soldering at 275 °C for 10 s; compatible with standard through-hole assembly lines |
| Bidirectional clamping symmetry | Eliminates need for polarity-aware layout or external series components in AC-coupled or differential signal protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22CA | DO-214AA package; 22 V VBR; same 600 W rating but lower IPPM (19.2 A); 10% smaller footprint | Preferred for space-constrained SMT layouts; requires rework of pad stack and stencil; not through-hole drop-in | Select SMBJ22CA when board real estate is limited and SMT assembly is available; verify thermal relief on high-current traces. |
| 1.5KE22CA | DO-201AD package; identical VBR, VWM, VC; higher 1.5 kW rating but larger size and 10× higher junction capacitance | Used where higher single-pulse energy margin is needed; unsuitable for high-frequency signal lines due to ~200 pF CJ | Choose 1.5KE22CA only for low-speed power rail protection where capacitance-induced signal distortion is not critical. |
Compared with SMBJ22CA and 1.5KE22CA, P6KE22CAHE3/54 offers optimal balance of through-hole manufacturability, AEC-Q101 compliance, and low-capacitance bidirectional clamping - making it the default choice for automotive and industrial through-hole designs requiring qualification and proven field reliability.

FAQ
What is the clamping voltage of P6KE22CAHE3/54 at its rated peak pulse current?
The P6KE22CAHE3/54 has a maximum clamping voltage (VC) of 30.6 V at its rated peak pulse current (IPPM) of 19.6 A, measured with a 10/1000 μs waveform. This value is specified in the Vishay datasheet Document Number 88369, page 2, and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The P6KE22CAHE3/54 maintains this clamping performance across its full operating temperature range.
Is P6KE22CAHE3/54 suitable for automotive applications?
Yes, P6KE22CAHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units and body electronics. Its DO-15 package meets JESD 22-B106 solderability requirements, and its 175 °C maximum junction temperature supports under-hood deployment. The HE3 suffix confirms AEC-Q101 qualification per Vishay's ordering nomenclature - making P6KE22CAHE3/54 appropriate for safety-critical automotive transient suppression.
How does the bidirectional design of P6KE22CAHE3/54 affect PCB layout?
The bidirectional design of P6KE22CAHE3/54 eliminates polarity marking and orientation constraints - either lead may connect to either side of the protected line. This simplifies PCB layout by removing the need for cathode/anode alignment checks and enables symmetric placement across differential pairs or AC-coupled signals. No silkscreen polarity indicator is required, reducing assembly error risk and supporting automated optical inspection.
What is the maximum steady-state power dissipation of P6KE22CAHE3/54?
The P6KE22CAHE3/54 has a maximum steady-state power dissipation (PD) of 5.0 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C, per Figure 5 in the Vishay datasheet. This rating applies to continuous DC or low-duty-cycle conditions - not transient suppression. For reliable long-term operation, designers must ensure ambient and trace thermal resistance keep junction temperature below 175 °C, especially in enclosed or high-temperature environments.
Does P6KE22CAHE3/54 have a defined junction capacitance value?
No, junction capacitance (CJ) is not specified for P6KE22CAHE3/54 in the official Vishay datasheet Document Number 88369. While Figure 4 shows typical CJ curves for unidirectional P6KE devices, bidirectional types like P6KE22CAHE3/54 omit this parameter because capacitance varies significantly with bias voltage and is not characterized for AC signal integrity applications. Designers requiring low-capacitance protection should consider SMAJ/SMBJ alternatives instead of relying on P6KE22CAHE3/54 for high-speed data lines.
