Product details
Overview
1.5KE62C from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with 62V nominal breakdown voltage (VBR min 55.8V, max 68.2V), 50.2V working stand-off voltage (VWM), and 89.0V clamping voltage (VC) at 17A peak impulse current - designed for automotive and industrial power rail surge protection.
For engineers reviewing the 1.5KE62C datasheet, 1.5KE62C pinout, 1.5KE62C application, or 1.5KE62C equivalent, key selection criteria include clamping performance under ISO 7637-2 Pulse 1/2a/2b/3a/3b, AEC-Q101 qualification status, thermal derating above 25°C, and compatibility with 10/1000μs surge waveforms in DC power systems.
Technical Context
The 1.5KE62C operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its VBR range (55.8–68.2V @ 1mA), clamping transients to ≤89.0V at 17A IPP while maintaining low dynamic impedance and sub-1ps response time from 0V to VBR. It supports single-pulse 1500W dissipation at TA = 25°C with junction temperature rated from –55°C to +175°C.
Its DO-201 package features pure tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and polarity marked by cathode band. Electrical characteristics are specified per ANSI/IEEE C62.35, with leakage current ≤1μA at 50.2V and forward voltage ≤3.5V at 50A for unidirectional operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1mA | 55.8V min to 68.2V max - defines precise avalanche onset threshold for reliable overvoltage triggering |
| VWM | 50.2V - maximum continuous reverse operating voltage before leakage exceeds 1μA |
| VC @ IPP = 17A | 89.0V - clamped voltage during 10/1000μs surge, limiting downstream IC stress |
| PPK | 1500W - peak pulse power handling capability at TA = 25°C, derated linearly above ambient |
| TJ Range | –55°C to +175°C - enables deployment in under-hood automotive and industrial environments |
| Response Time | <1.0ps - ensures suppression initiates before transient energy couples into protected circuitry |
| Leakage ID @ VWM | <1μA - minimizes standby power loss in battery-backed or low-power systems |
Pinout & Package
DO-201 axial-leaded package with cathode band marking polarity; leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ64A | 64V VBR (min 57.6V), 87.1V VC @ 17.2A, DO-214AC package, 400W PPK rating | Lower power rating limits use to non-load-dump scenarios; surface-mount only | Select when board space constraints prohibit axial DO-201 and surge energy is limited to ≤400W |
| ON Semiconductor 1N6290A | Identical electrical specs (62V nominal, VBR 58.9–65.1V, VC 85.0V @ 18A), same DO-201 package, AEC-Q101 qualified | No functional difference; alternate manufacturer sourcing for supply chain diversification | Direct second-source option with identical pinout, thermal profile, and qualification status |
Compared with 1.5KE62C, SMAJ64A offers smaller footprint but sacrifices 73% peak power handling and lacks AEC-Q101 validation, while 1N6290A delivers identical protection performance and automotive qualification with no design or layout changes required.

FAQ
What is the clamping voltage of the 1.5KE62C under a standard 10/1000μs surge?
The 1.5KE62C clamps to a maximum of 89.0V at 17A peak impulse current (IPP) when subjected to a 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage seen by downstream circuitry during surge events - critical for ensuring protected ICs remain within absolute maximum ratings. The 1.5KE62C achieves this with low dynamic impedance and sub-1ps response time.
Is the 1.5KE62C AEC-Q101 qualified?
Yes, the 1.5KE62C is AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor documentation for the 1.5KE series. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge (ESD), making the 1.5KE62C suitable for automotive powertrain and body electronics applications where reliability under harsh conditions is mandatory.
What is the difference between 1.5KE62C and 1.5KE62A?
The 1.5KE62C has a VBR range of 55.8V–68.2V and VC of 89.0V @ 17A, while the 1.5KE62A variant specifies tighter VBR (58.9V–65.1V) and lower VC (85.0V @ 18A). Both share the same DO-201 package and AEC-Q101 qualification, but the 1.5KE62A offers improved clamping consistency for designs requiring tighter voltage margins - the 1.5KE62C remains optimal for cost-sensitive, high-volume automotive applications where broader VBR tolerance is acceptable.
Can the 1.5KE62C be used in bidirectional configurations?
No, the 1.5KE62C is unidirectional only, indicated by the "C" suffix and cathode band marking. Bidirectional operation requires the "CA" suffix variant (e.g., 1.5KE62CA), which uses a symmetrical dual-diode structure. Using the 1.5KE62C in reverse-biased signal lines risks forward conduction and failure - always verify polarity alignment and select CA-suffixed parts for AC or data-line protection.
What is the maximum steady-state power dissipation for the 1.5KE62C?
The 1.5KE62C has a steady-state power dissipation (PD) rating of 5W at lead temperature TL = 75°C, measured with 0.375" (9.5mm) lead lengths mounted on a 0.6" × 0.6" copper pad. This rating applies only to continuous DC or low-frequency conditions - the device is not intended for sustained power dissipation; its primary function is transient suppression, where 1500W peak power is allowed for non-repetitive 1ms pulses per Fig.3 in the 1.5KE62C datasheet.
