Product details
Overview
P4KE62HE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 53.0 V stand-off voltage (VWM), 58.9–65.1 V breakdown range (VBR at 1.0 mA), 85.0 V maximum clamping voltage (VC) at 4.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive ECUs, industrial sensor interfaces, and power supply input stages.
For engineers reviewing the P4KE62HE3/73 datasheet, P4KE62HE3/73 pinout, P4KE62HE3/73 application, or P4KE62HE3/73 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical dimensions, clamping behavior under surge, and direct alternatives for circuit protection redesigns requiring RoHS-compliant, high-reliability TVS devices.
Technical Context
This device operates as a silicon avalanche diode optimized for transient suppression in unidirectional configurations. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 μA at VWM), while the 66 °C/W junction-to-lead thermal resistance supports reliable power dissipation during repetitive surges up to 0.01% duty cycle.
The P4KE62HE3/73 is rated for 175 °C maximum junction temperature and meets JESD 201 Class 2 whisker resistance. Its 1.5 W steady-state power dissipation (at TL = 75 °C) and 40 A 8.3 ms forward surge capability enable use in harsh environments where inductive switching transients exceed 1 kV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 53.0 V - Maximum continuous reverse working voltage before significant leakage; sets safe operating margin below system rail. |
| VBR min/max | 58.9 V / 65.1 V at 1.0 mA - Tight breakdown window ensures predictable turn-on during transients without premature conduction. |
| VC @ IPPM | 85.0 V at 4.7 A - Clamping voltage limits downstream IC stress during 10/1000 μs surge; defines protected circuit's max exposure. |
| PPPM | 400 W - Peak pulse power handling with standard 10/1000 μs waveform; validates suitability for IEC 61000-4-5 Level 3/4 tests. |
| TJ max | +175 °C - Enables operation in under-hood automotive or high-ambient industrial enclosures without derating. |
| AEC-Q101 | Qualified - Confirmed reliability for automotive electronics per stress test requirements including HTOL, TC, and HTRB. |
| Package | DO-41 (DO-204AL) - Standard axial-leaded through-hole package with 25.4 mm minimum body length and 0.86 mm lead diameter. |
Pinout & Package
DO-41 (DO-204AL) package: axial-leaded, molded epoxy body with glass-passivated chip; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102; cathode indicated by color band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path during positive surge | Connected to lower-potential side (e.g., GND) in unidirectional configuration; carries full surge current during clamping. |
| Cathode | Reverse-biased terminal during normal operation | Marked with color band; connected to protected line (e.g., +12 V rail); initiates avalanche breakdown when VWM exceeded. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A | Surface-mount SMB package; same VWM (48.4 V), slightly higher VC (96.8 V at 4.1 A); 600 W PPPM. | Requires PCB rework for SMT layout; better suited for space-constrained designs with automated assembly. | Select when board real estate is limited and reflow compatibility is required; verify thermal pad design for 600 W dissipation. |
| 1.5KE62A | Same DO-41 package but higher PPPM (1500 W); wider VBR range (58.9–65.1 V); no AEC-Q101 qualification. | Used in non-automotive industrial power systems where qualification is not mandated and higher surge margin is needed. | Choose for cost-sensitive, non-automotive applications needing greater single-pulse energy absorption without qualification overhead. |
Compared with SMBJ60A and 1.5KE62A, the P4KE62HE3/73 uniquely combines AEC-Q101 qualification, DO-41 through-hole compatibility, and precise 400 W/85 V clamping performance - making it the preferred choice for automotive and high-reliability industrial replacements where qualification and legacy footprint retention are mandatory.

FAQ
What is the clamping voltage of the P4KE62HE3/73 and how does it protect downstream circuits?
The P4KE62HE3/73 has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (10/1000 μs waveform). This value defines the highest voltage imposed on the protected line during a surge event. By limiting transient overvoltage to ≤85 V, the P4KE62HE3/73 prevents breakdown or latch-up in downstream components such as microcontrollers, CAN transceivers, or MOSFET gate oxides that typically have absolute maximum ratings near 100 V. Its fast avalanche response ensures clamping occurs within nanoseconds.
Is the P4KE62HE3/73 suitable for automotive applications, and what qualification does it hold?
Yes, the P4KE62HE3/73 is explicitly qualified to AEC-Q101 standards, as confirmed in Vishay's datasheet revision 16-Sep-2021 (Document Number: 88365). This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated temperature-humidity stress (HAST), validating its reliability in under-hood and chassis-mounted automotive electronics. The HE3 suffix denotes AEC-Q101 compliance and JESD 201 Class 2 whisker resistance.
How does the P4KE62HE3/73 differ from the commercial-grade P4KE62A-E3/73?
The P4KE62HE3/73 differs from P4KE62A-E3/73 solely in qualification and process control: both share identical electrical specs (VWM = 53.0 V, VBR = 58.9–65.1 V, VC = 85.0 V), DO-41 package, and RoHS compliance. However, the HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker testing, whereas the E3 suffix indicates commercial-grade only. No parametric or mechanical differences exist beyond the certified reliability screening.
What is the thermal resistance of the P4KE62HE3/73 and how does it affect power handling?
The P4KE62HE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, measured with lead length L = 10 mm. This parameter determines how effectively heat generated during surge events transfers from the silicon junction to the PCB copper or heatsink. At 400 W peak pulse power, even brief events raise junction temperature significantly - hence the 0.01% duty cycle limit. For continuous operation, the 1.5 W steady-state power rating applies at TL = 75 °C, directly governed by RθJL.
Can the P4KE62HE3/73 be used in bidirectional configurations?
No, the P4KE62HE3/73 is a unidirectional TVS diode, as indicated by the "A" suffix (e.g., P4KE62A) and absence of "CA" in the part number. Bidirectional variants like P4KE62CA exist for AC-line or differential-signal protection but feature symmetric breakdown in both polarities. Using P4KE62HE3/73 in reverse-biased AC applications would result in forward conduction and potential failure. Always match the device polarity to the circuit's voltage reference and surge direction.
