Product details
Overview
1.5KE62 from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode with a nominal breakdown voltage of 62 V, minimum VBR of 55.8 V at 1.0 mA test current, maximum clamping voltage of 89.0 V at 17 A peak pulse current, and DO-201 axial package. It protects automotive power electronics and industrial control inputs against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5KE62 datasheet, 1.5KE62 pinout, 1.5KE62 application, or 1.5KE62 equivalent, key selection criteria include its 62 V standoff capability, sub-1 ps response time for unidirectional operation, 175 °C junction temperature rating, AEC-Q101 qualification option (1.5KE62A), and compatibility with lead-free reflow soldering per J-STD-002.
Technical Context
The 1.5KE62 operates as a unidirectional avalanche diode, clamping overvoltage transients by entering breakdown when reverse voltage exceeds VBR = 55.8–68.2 V. Its low dynamic impedance ensures stable clamping under 10/1000 µs surge waveforms up to 1500 W.
It features a cathode-banded DO-201 package with pure tin-plated leads, meets UL 94V-0 flammability, and supports steady-state power dissipation of 5 W at 75 °C lead temperature. Junction temperature range is −55 °C to +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 55.8 V at 1.0 mA - defines lowest voltage at which device reliably enters avalanche conduction |
| VBR (max) | 68.2 V at 1.0 mA - sets upper bound for production variation in breakdown threshold |
| VC @ IPP | 89.0 V at 17 A - maximum voltage seen by protected circuit during worst-case 10/1000 µs surge |
| PPK | 1500 W - peak non-repetitive surge power handling per JEDEC standard waveform |
| VWM | 50.2 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| TJ max | +175 °C - enables use in under-hood automotive environments without derating |
| Response time | <1.0 ps - ensures clamping initiates before transient energy couples into downstream ICs |
Pinout & Package

Applications
| Automotive Power Input Protection | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: 12 V battery-fed ECU power rail exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS clamps reverse-polarity and surge events before they reach DC-DC converters and microcontrollers. Use Value: Limits transient voltage to ≤89.0 V, preventing damage to 36 V-rated input stages and meeting OEM immunity requirements per ISO 7637-2. | Use Scenario: 24 V digital input channel on programmable logic controller receiving signals from field sensors. IC Role / Device Role / Timing Role: Standoff protector placed between terminal block and optocoupler input, absorbing fast transients induced by relay switching. Use Value: Sub-1 ps response ensures clamping occurs within first nanosecond of transient onset, preserving signal integrity and preventing false triggering. |
| LED Driver Overvoltage Clamp | Motor Drive Gate Driver Protection |
Use Scenario: Constant-current LED driver board powered from 48 V bus in commercial lighting fixture. IC Role / Device Role / Timing Role: Primary overvoltage clamp on input capacitor node, shunting surges caused by nearby AC line switching. Use Value: 1500 W surge rating handles repetitive 10/1000 µs pulses common in building automation systems without degradation. | Use Scenario: Isolated gate driver supply rail in BLDC motor inverter exposed to Miller-induced spikes. IC Role / Device Role / Timing Role: Secondary protection on low-voltage auxiliary supply (e.g., 15 V bias rail), limiting coupling from high-dV/dt power stage. Use Value: 50.2 V working voltage allows safe operation across full 12–15 V bias range while clamping spikes above 55.8 V. |
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 VBR min (64.0 V), 1000 W PPK, 100 A IPP rating | Lower surge rating; surface-mount only; better suited for PCB space-constrained designs | Select SMBJ64A when board area is limited and 1000 W surge capacity suffices |
| 1N6290A | Same family; tighter VBR tolerance (58.9–65.1 V vs. 55.8–68.2 V); AEC-Q101 qualified | Identical function and package; certified for automotive use where reliability validation is mandatory | Choose 1N6290A (1.5KE62A) when AEC-Q101 compliance is required for production vehicles |
Compared with SMBJ64A, the 1.5KE62 offers 50% higher surge power (1500 W vs. 1000 W) and axial through-hole mounting for high-reliability mechanical retention; compared with 1N6290A, it trades tighter VBR tolerance and automotive qualification for lower cost in non-automotive industrial applications.

FAQ
What is the maximum clamping voltage of the 1.5KE62 under a 10/1000 µs surge?
The 1.5KE62 has a maximum clamping voltage (VC) of 89.0 V at 17 A peak pulse current (IPP) under the standardized 10/1000 µs waveform. This value is measured per JEDEC standards and represents the highest voltage the protected circuit will experience during worst-case transient events. The 1.5KE62 maintains this clamping performance across its specified junction temperature range of −55 °C to +175 °C.
Is the 1.5KE62 unidirectional or bidirectional?
1.5KE62 is a unidirectional transient voltage suppressor, intended for DC line protection where polarity is fixed (e.g., 12 V or 24 V supply rails). Its cathode band marks the terminal connected to the line being protected; the anode connects to ground. Bidirectional operation requires the 1.5KE62CA variant, which is not interchangeable with the 1.5KE62.
Does the 1.5KE62 meet automotive qualification standards?
The base 1.5KE62 is not AEC-Q101 qualified; however, its direct variant 1.5KE62A (JEDEC type 1N6290A) is fully AEC-Q101 qualified and shares identical electrical parameters except for tighter VBR tolerance (58.9–65.1 V) and extended reliability testing. For automotive production, specify 1.5KE62A or 1N6290A-not 1.5KE62-to ensure compliance.
What is the working stand-off voltage (VWM) of the 1.5KE62?
The working stand-off voltage (VWM) of the 1.5KE62 is 50.2 V, meaning it remains in high-impedance blocking mode with leakage current <1 µA up to this DC or RMS voltage level. This allows safe integration on 48 V nominal systems with margin, but prohibits use on 60 V rails where sustained operation would cause excessive leakage or thermal stress.
What package type does the 1.5KE62 use, and what are its mounting considerations?
The 1.5KE62 uses the DO-201 axial-leaded package with cathode band marking, pure tin-plated leads compliant with J-STD-002, and UL 94V-0 molding compound. Mounting requires ≥0.375" (9.5 mm) lead length for rated 5 W steady-state dissipation at 75 °C; shorter leads require derating. Through-hole placement supports mechanical robustness in high-vibration environments like automotive and industrial machinery.
