Product details
Overview
1.5KE62C-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for clamping voltage transients on signal and power lines. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at 1 mA), 1500 W peak pulse power (10/1000 µs), 85.0 V maximum clamping voltage at 17.6 A, and operates across –55 °C to +175 °C junction temperature. It protects MOSFETs and ICs in automotive and industrial power supply rails.
For engineers reviewing the 1.5KE62C-E3/73 datasheet, 1.5KE62C-E3/73 pinout, 1.5KE62C-E3/73 application, or 1.5KE62C-E3/73 equivalent, this page delivers verified electrical specs, thermal derating behavior, clamping performance under surge conditions, RoHS-compliant packaging details, and direct alternative part comparisons for ESD and lightning transient protection design.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its symmetrical clamping behavior applies equally in both directions, with no polarity marking required on the case.
The device is rated for 1500 W peak pulse power per 10/1000 µs waveform at TA = 25 °C, derating linearly above 25 °C with RθJA = 75 °C/W and RθJL = 15.4 °C/W. It supports unidirectional surge current up to 200 A (8.3 ms half-sine) only in unidirectional variants - not applicable to 1.5KE62C-E3/73 due to its bidirectional construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1 mA - defines reliable conduction onset under transient stress |
| VWM | 53.0 V - maximum continuous reverse working voltage before leakage exceeds 1 μA |
| VC @ IPPM | 85.0 V at 17.6 A - clamped voltage during full 1500 W surge, limiting downstream stress |
| PPPM | 1500 W (10/1000 µs) - peak transient energy absorption capability without failure |
| TJ range | –55 °C to +175 °C - enables use in under-hood automotive and industrial environments |
| Package | Case Style 1.5KE - axial-lead DO-201AD package, UL 94 V-0 compliant epoxy body |
| RoHS | E3 suffix - RoHS-compliant matte tin-plated leads, JESD 201 Class 1A whisker tested |
Pinout & Package
1.5KE62C-E3/73 is housed in a DO-201AD (Case Style 1.5KE) axial-leaded package with no polarity marking - consistent with bidirectional operation. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Suppresses load-dump and jump-start transients on 12 V battery-fed ECUs and body control modules. IC Role / Device Role / Timing Role: Bidirectional TVS placed across power input to clamp ±100 V spikes before they reach LDOs or microcontrollers. Use Value: Limits voltage to ≤85 V during 1500 W surges, preventing latch-up or gate oxide rupture in downstream semiconductors. | Use Scenario: Shields analog sensor outputs (e.g., pressure, temperature) connected to long harnesses in factory automation systems. IC Role / Device Role / Timing Role: Placed differential-mode across signal pair to suppress common-mode ESD and fast-rising EFT bursts. Use Value: Clamps transients before they couple into op-amp inputs or ADC front-ends, maintaining measurement integrity. |
| Telecom Line Interface Protection | Consumer Power Adapter Input Stage |
Use Scenario: Protects Ethernet PHY interfaces and DSL line drivers against induced lightning surges on outdoor cabling. IC Role / Device Role / Timing Role: Used in conjunction with common-mode chokes to absorb differential-mode surges on twisted-pair lines. Use Value: Withstands 10/1000 µs surges up to 17.6 A while holding clamped voltage below IC absolute maximum ratings. | Use Scenario: Guards AC-DC adapter primary-side rectifier output against mains-borne transients and capacitor discharge spikes. IC Role / Device Role / Timing Role: Mounted across bulk capacitor to clamp overvoltage events before reaching PWM controller ICs. Use Value: Absorbs 1500 W pulses without degradation, enabling compliance with IEC 61000-4-5 Level 3 (1 kV/2 Ω) testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower PPPM (600 W), smaller SMB package (vs. DO-201AD), VC = 103 V @ 5.8 A | Preferred where board space is constrained and surge energy is ≤600 W | Select SMBJ64CA when footprint reduction outweighs need for 1500 W rating |
| 1.5KE62CA | Same 1.5KE package and electrical specs, but lacks E3 RoHS/commercial-grade suffix - base variant without JESD 201 whisker test | Acceptable for non-automotive, non-high-reliability commercial designs | Choose 1.5KE62CA only if RoHS compliance and whisker resistance are not required |
Compared with SMBJ64CA and 1.5KE62CA, the 1.5KE62C-E3/73 provides higher surge robustness in a through-hole package with certified RoHS and whisker resistance - making it optimal for industrial and automotive applications demanding proven 1500 W clamping and long-term lead reliability.

FAQ
What is the breakdown voltage tolerance for 1.5KE62C-E3/73?
The 1.5KE62C-E3/73 has a specified breakdown voltage range of 58.9 V to 65.1 V at 1 mA test current, corresponding to ±10 % tolerance around the nominal 62 V rating. This VBR window ensures predictable clamping onset across production lots and temperature extremes, critical for coordinating with downstream overvoltage protection thresholds in circuits using the 1.5KE62C-E3/73.
Is 1.5KE62C-E3/73 suitable for automotive applications?
Yes, 1.5KE62C-E3/73 is qualified to AEC-Q101 when ordered with the HE3 suffix (e.g., 1.5KE62CAHE3_B). The base 1.5KE62C-E3/73 is commercial grade and RoHS-compliant but not AEC-Q101 certified. For automotive use, confirm ordering code includes HE3 and revision letter (e.g., B); the 1.5KE62C-E3/73 itself meets thermal and surge requirements but lacks formal qualification documentation unless specified.
What does the "C" in 1.5KE62C-E3/73 signify?
The "C" in 1.5KE62C-E3/73 denotes bidirectional configuration - meaning the device clamps symmetrically for positive and negative transients, with no cathode/anode distinction. Unlike unidirectional variants (e.g., 1.5KE62A), the 1.5KE62C-E3/73 has no color band marking and is used where AC signals, floating references, or dual-polarity surges require equal protection in both directions.
How does the clamping voltage of 1.5KE62C-E3/73 compare to its breakdown voltage?
The 1.5KE62C-E3/73 clamps at 85.0 V when subjected to its peak pulse current of 17.6 A (10/1000 µs), which is approximately 36 % above its minimum breakdown voltage of 58.9 V. This VC–VBR margin reflects the device's incremental surge resistance and ensures safe headroom below typical 100 V absolute maximum ratings of protected ICs - a key design parameter confirmed in the 1.5KE62C-E3/73 datasheet.
Can 1.5KE62C-E3/73 be used in parallel for higher power handling?
While the 1.5KE62C-E3/73 datasheet states TVS diodes "can be used in series or parallel to increase peak power ratings," paralleling requires careful matching of VBR and dynamic impedance to avoid current imbalance. Vishay does not guarantee matched characteristics across units, so derating and thermal coupling analysis are essential. For most designs, selecting a single higher-rated device (e.g., 1.5KE75C) is preferred over paralleling multiple 1.5KE62C-E3/73 units.
