Product details
Overview
1.5KE62A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of sensitive electronics. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at 1 mA), 1500 W peak pulse power (10/1000 µs), clamping voltage of 85.0 V at 17.6 A, and operates across –55 °C to +175 °C junction temperature. It is used in DC power rail protection for industrial motor drives and automotive ECUs.
For engineers reviewing the 1.5KE62A-E3/54 datasheet, 1.5KE62A-E3/54 pinout, 1.5KE62A-E3/54 application, or 1.5KE62A-E3/54 equivalent, this page delivers verified electrical specs, thermal derating behavior, clamping performance under surge, RoHS-compliant packaging details, and direct alternatives for circuit-level ESD/lightning transient hardening.
Technical Context
This unidirectional TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its 1500 W peak pulse rating is defined per 10/1000 µs waveform with 0.01% duty cycle, and it exhibits a maximum clamping voltage of 85.0 V at 17.6 A IPPM - critical for limiting stress on downstream MOSFETs or microcontrollers during transients.
Thermal design is supported by RθJA = 75 °C/W and RθJL = 15.4 °C/W, enabling reliable operation up to 175 °C junction temperature. The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 1A whisker testing, confirming suitability for high-reliability commercial PCB assembly.

Applications
| Industrial Motor Drives | Automotive Engine Control Units |
|---|---|
Use Scenario: Protection of 48 V DC bus against inductive kickback from solenoid valves and relay coils. IC Role / Device Role / Timing Role: Unidirectional TVS placed between rail and ground to clamp transients before they reach gate drivers or MCU I/O. Use Value: Limits voltage excursion to ≤85 V during 17.6 A surge, preventing latch-up or oxide breakdown in 65 V-rated FETs. |
Use Scenario: Guarding LIN bus transceivers and sensor supply lines against load dump and jump-start events. IC Role / Device Role / Timing Role: Primary front-end transient suppressor on 12 V auxiliary rails feeding engine control modules. Use Value: Withstands 200 A non-repetitive forward surge (8.3 ms), surviving ISO 7637-2 Pulse 5a without degradation. |
| Telecom Power Feeds | Consumer Appliance Control Boards |
Use Scenario: Shielding PoE-powered Ethernet switch ports from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Secondary-stage TVS after gas discharge tube (GDT), providing fast sub-nanosecond clamping. Use Value: <1 ns response time ensures clamping occurs before GDT fires, reducing let-through energy to <10 mJ. |
Use Scenario: Safeguarding microcontroller reset lines and button inputs from ESD and EFT in washing machine UI boards. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp on 3.3 V or 5 V logic rails near connectors. Use Value: Maintains <1 µA leakage at 53 V, ensuring no impact on pull-up/pull-down bias networks during normal operation. |
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 (SMB), 64 V VBR, 600 W PPPM, higher RθJA (110 °C/W) | Lower power rating limits use to sub-10 A surges; surface-mount form factor requires layout change | Select when board space is constrained and peak surge current remains below 10 A. |
| 1.5KE62CA | Bidirectional variant, same VBR range and PPPM, but symmetrical clamping in both polarities | Required for AC-coupled signal lines or floating buses where polarity reversal may occur | Choose only if bidirectional protection is mandated - not a drop-in replacement due to polarity and marking differences. |
Compared with 1.5KE62A-E3/54, SMBJ64A offers smaller footprint but sacrifices 60% peak power handling and thermal performance; 1.5KE62CA provides identical surge capability but requires redesign for symmetric clamping - neither is pin-compatible, and both demand verification of layout, thermal path, and system-level transient profile.

FAQ
What is the breakdown voltage tolerance for 1.5KE62A-E3/54?
The 1.5KE62A-E3/54 has a specified breakdown voltage range of 58.9 V to 65.1 V at 1.0 mA test current. This ±5% tolerance ensures consistent clamping initiation across production lots while allowing margin for temperature drift and aging. The value is measured per JEDEC standard and confirmed in Vishay's 88301 datasheet revision 09-Aug-2022.
Is 1.5KE62A-E3/54 suitable for automotive under-hood applications?
Yes, 1.5KE62A-E3/54 supports junction temperatures up to +175 °C and is rated for commercial-grade operation. While not AEC-Q101 qualified (only HE3 variants like 1.5KE62AHE3_B are), its thermal robustness, 200 A IFSM, and UL 94 V-0 package make it appropriate for non-safety-critical under-hood locations such as body control module power inputs where qualification is not mandated.
How does the clamping voltage of 1.5KE62A-E3/54 compare to its breakdown voltage?
At its rated peak pulse current of 17.6 A (10/1000 µs), the 1.5KE62A-E3/54 clamps to 85.0 V - approximately 33% above its minimum VBR of 58.9 V. This clamping ratio reflects low dynamic impedance and confirms effective transient energy diversion without excessive overvoltage stress on protected components.
Can 1.5KE62A-E3/54 be used in parallel to increase surge handling?
Yes, multiple 1.5KE62A-E3/54 devices can be paralleled to distribute surge current, but matching VBR (58.9–65.1 V) is essential to ensure balanced current sharing. Vishay's application notes recommend using matched lots and symmetric PCB layout; derating total PPPM by 15–20% is advised to account for minor parameter variation.
What is the lead finish and solderability specification for 1.5KE62A-E3/54?
The 1.5KE62A-E3/54 features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. It passes solder dip testing at 275 °C for 10 seconds (per JESD 22-B106) and meets JESD 201 Class 1A whisker resistance, making it suitable for lead-free reflow and wave soldering in high-volume commercial manufacturing.
