Product details
Overview
P4KE62AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on DC power rails and signal lines. It features 53.0 V standoff voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1.0 mA, 85.0 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P4KE62AHE3/54 datasheet, P4KE62AHE3/54 pinout, P4KE62AHE3/54 application, or P4KE62AHE3/54 equivalent, key selection criteria include clamping voltage (VC = 85.0 V), AEC-Q101 qualification, DO-41 mechanical compatibility, and unidirectional polarity with cathode band marking.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 μA at VWM), while the 66 °C/W junction-to-lead thermal resistance supports reliable surge energy dissipation under transient conditions.
The device complies with AEC-Q101 for automotive-grade reliability and uses matte tin-plated leads solderable per J-STD-002. It is rated for -55 °C to +175 °C operating junction temperature and exhibits a 0.104 %/°C temperature coefficient of VBR - critical for stable clamping across wide ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - maximum continuous reverse working voltage before significant leakage; defines safe DC rail operating margin. |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1.0 mA - tight 10% tolerance ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 85.0 V at IPPM = 4.7 A - limits downstream voltage stress during 10/1000 μs surge events. |
| PPPM (Peak Pulse Power) | 400 W - sustains single 10/1000 μs surges without degradation; derates linearly above 25 °C ambient. |
| IFSM (Surge Current) | 40 A (8.3 ms half-sine) - handles repetitive inductive switch-off spikes in motor drivers and solenoid controls. |
| TJ max. | +175 °C - enables operation in under-hood automotive environments and high-power industrial enclosures. |
| Leakage ID | ≤1.0 μA at VWM - minimizes standby power loss in battery-backed or low-quiescent systems. |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with UL 94 V-0 rating. Cathode indicated by color band on one end; anode is unmarked lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded lead) | Forward current entry / reverse voltage reference | Connected to lower-potential side (e.g., GND or return path); defines unidirectional conduction direction. |
| Cathode (banded lead) | Avalanche clamping node / transient sink | Connected to protected line (e.g., 48 V rail or CAN-H); conducts surge current to ground when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift in harsh environments. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces requiring zero-failure reliability. |
| 400 W 10/1000 μs pulse rating | Withstands ISO 7637-2 Pulse 1/2a/3a transients without degradation - suitable for 12 V/24 V vehicle electrical systems. |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage exposure to downstream ICs; critical for protecting 75 V-rated MOSFETs and 5 V/3.3 V logic inputs. |
| Matte tin-plated leads | Enables robust solder joint formation per J-STD-002; meets JESD 201 Class 2 whisker resistance for long-term storage. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | DO-214AA package; 64 V VWM; 70.1 V VC at 5.7 A; 600 W PPPM | Higher power rating but larger footprint; requires PCB re-layout | Select SMBJ64A when higher surge margin (>600 W) is required and board space permits SMC/SMB package. |
| 1.5KE62A | Same DO-41 package; identical VWM/VBR/VC specs; 1500 W PPPM (10/1000 μs) | Higher peak power handling but larger junction capacitance (≈150 pF vs. ~50 pF) | Choose 1.5KE62A only if system-level surge testing demands >400 W capability and signal-line capacitance is not critical. |
Compared with P4KE62AHE3/54, SMBJ64A offers greater surge capacity in a surface-mount format ideal for automated assembly, while 1.5KE62A delivers triple the pulse power in the same through-hole footprint but increases capacitive loading on high-speed lines.

FAQ
What is the clamping voltage of P4KE62AHE3/54 and how does it protect downstream components?
The P4KE62AHE3/54 has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (IPPM) with a 10/1000 μs waveform. This means that when a transient exceeds the device's breakdown voltage, it rapidly transitions into low-impedance conduction and holds the protected line at or below 85.0 V - safely within the absolute maximum ratings of most 100 V-rated MOSFETs and 75 V-input DC/DC converters. The P4KE62AHE3/54 thus prevents overvoltage damage by diverting surge energy to ground before critical components experience destructive stress.
Is P4KE62AHE3/54 qualified for automotive applications?
Yes, the HE3 suffix explicitly denotes AEC-Q101 qualification for P4KE62AHE3/54. This certification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating suitability for under-hood and chassis-mounted automotive electronics. The P4KE62AHE3/54 is commonly deployed in engine control modules, body control units, and ADAS camera power supplies where failure modes must meet zero-defect requirements.
How does the DO-41 package of P4KE62AHE3/54 affect thermal performance?
The DO-41 package of P4KE62AHE3/54 provides a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, enabling efficient heat transfer to PCB copper pours or heatsinks via axial leads. With a maximum power dissipation (PD) of 1.5 W on an infinite heatsink at TL = 75 °C, the P4KE62AHE3/54 relies on lead conduction rather than case radiation - making thermal design dependent on lead length, pad size, and copper area. Shorter leads and wider traces improve sustained surge handling beyond single-pulse ratings.
What is the significance of the "HE3" suffix in P4KE62AHE3/54?
The "HE3" suffix in P4KE62AHE3/54 indicates two key attributes: RoHS-compliance (E3) and AEC-Q101 qualification (H). The E3 portion confirms matte tin plating meeting JESD 201 Class 2 whisker resistance, while the H prefix certifies full automotive qualification - distinguishing it from commercial-grade "E3" variants like P4KE62AE3/54. This makes P4KE62AHE3/54 appropriate for safety-critical automotive designs where traceability and process control are mandatory.
Can P4KE62AHE3/54 be used in bidirectional configurations?
No, P4KE62AHE3/54 is a unidirectional TVS diode, identifiable by its cathode band marking. Bidirectional operation requires a CA-suffixed part such as P4KE62CA. Using P4KE62AHE3/54 in reverse-biased AC signal paths would result in forward conduction and potential failure during negative half-cycles. For bidirectional protection, always select the CA variant - the P4KE62AHE3/54 is strictly intended for DC rail or single-polarity signal line clamping.
