Product details
Overview
P6KE62CHE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 62 V breakdown voltage (VBR min = 58.9 V, max = 65.1 V), 85 V maximum clamping voltage at 7.1 A peak pulse current, 600 W peak pulse power rating (10/1000 µs waveform), and AEC-Q101 qualification for automotive-grade reliability. It protects MOSFETs, ICs, and sensor interfaces against inductive switching transients and ESD events.
For engineers reviewing the P6KE62CHE3/54 datasheet, P6KE62CHE3/54 pinout, P6KE62CHE3/54 application, or P6KE62CHE3/54 equivalent, key selection criteria include clamping voltage margin vs. protected device VDS/VCC, standoff voltage compatibility with operating rail (53.0 V VWM), thermal resistance (RθJL = 20 °C/W), and RoHS-compliant AEC-Q101 qualification for automotive electronics.
Technical Context
The P6KE62CHE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to transients. Its uni-directional polarity uses a cathode band marking, and it conducts only during reverse overvoltage events while remaining high-impedance under normal operation up to 53.0 V.
Clamping performance is defined by VC = 85 V at IPPM = 7.1 A (10/1000 µs), with low incremental surge resistance ensuring minimal voltage overshoot. Thermal design relies on RθJL = 20 °C/W to lead and TJ(max) = 175 °C, supporting sustained operation in engine control units and industrial power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V - Ensures reliable conduction onset above 53.0 V operating rail without false triggering |
| VWM | 53.0 V - Maximum continuous reverse working voltage; must exceed system DC rail by ≥10 % |
| VC @ IPPM | 85 V at 7.1 A - Clamped voltage seen by protected IC/MOSFET during worst-case 600 W transient |
| PPPM | 600 W - Peak pulse power handling per 10/1000 µs standard waveform; defines surge robustness class |
| IFSM | 100 A - Non-repetitive forward surge rating (8.3 ms half-sine); supports inrush current immunity |
| TJ(max) | 175 °C - Enables placement near hot components (e.g., power MOSFETs) without derating penalties |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance; determines heatsinking requirement for repetitive surges |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode identified by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); carries surge current to ground during clamping |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 48 V rail); avalanche breakdown initiates when voltage exceeds VBR |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A | DO-214AA package; 60 V VBR; 6.5 A IPPM; 600 W rating; same VC = 96.8 V | Surface-mount alternative; requires PCB rework; lower thermal resistance (RθJA = 40 °C/W vs. 75 °C/W) | Select SMBJ60A for space-constrained SMT designs where leaded DO-15 layout is unavailable. |
| 1.5KE62A | Same DO-204AC package; identical VBR/VWM/VC; 1500 W rating; higher IPPM = 14.3 A | Higher-power variant; larger junction; longer recovery time; not AEC-Q101 qualified | Choose 1.5KE62A only when surge threat exceeds 600 W (e.g., direct lightning coupling) and automotive qualification is unnecessary. |
Compared with SMBJ60A and 1.5KE62A, the P6KE62CHE3/54 uniquely combines AEC-Q101 qualification, DO-15 through-hole compatibility, and optimized 600 W clamping for cost-sensitive automotive and industrial power rails-without requiring PCB redesign or sacrificing reliability certification.

FAQ
What is the meaning of the 'HE3' and '/54' suffixes in P6KE62CHE3/54?
The 'HE3' suffix indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance-critical for automotive use. The '/54' denotes the preferred packaging code: 13-inch paper tape and reel containing 4000 units. This ensures consistent assembly-line feed and traceability for high-volume manufacturing of P6KE62CHE3/54.
Is P6KE62CHE3/54 suitable for bi-directional transient protection?
No, P6KE62CHE3/54 is strictly a uni-directional TVS diode, as confirmed by its part number ending in 'A' (not 'CA') and specification of forward voltage (VF = 3.5 V at 50 A). For bi-directional protection-such as AC lines or differential data buses-use P6KE62CA variants. Using P6KE62CHE3/54 in bi-directional applications risks forward conduction and failure during positive half-cycles.
How does the 85 V clamping voltage of P6KE62CHE3/54 impact system-level protection design?
The 85 V clamping voltage defines the maximum instantaneous voltage imposed on downstream components during a 7.1 A, 10/1000 µs transient. To ensure safety, protected devices (e.g., MOSFETs, regulators) must have voltage ratings exceeding 85 V with margin-typically ≥100 V for 48 V systems. This value directly determines minimum VDS selection for power switches in P6KE62CHE3/54-protected circuits.
Can P6KE62CHE3/54 be used in parallel for higher surge current handling?
No-P6KE62CHE3/54 should not be paralleled due to inherent parameter variation (VBR tolerance ±5 %) causing current imbalance and premature failure of the lower-VBR unit. For higher surge capability, select a single higher-rated device like 1.5KE62A or implement staged protection (e.g., MOV + P6KE62CHE3/54). Derating and thermal coupling make parallel P6KE62CHE3/54 configurations unreliable.
What is the significance of the 20 °C/W junction-to-lead thermal resistance for P6KE62CHE3/54?
RθJL = 20 °C/W means each watt of sustained power dissipation raises the junction temperature 20 °C above the lead temperature. In practice, this allows P6KE62CHE3/54 to handle repetitive surges if leads are soldered to wide copper pours or heatsinked traces. Without thermal relief, even low-duty-cycle surges can exceed TJ(max) = 175 °C-making RθJL critical for lifetime prediction in P6KE62CHE3/54 deployments.
