Product details
Overview
1.5KE62-E3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal 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), clamping voltage of 85.0 V at 17.6 A, and operates across –55 °C to +175 °C junction temperature. It is widely deployed in automotive power supply inputs and industrial sensor interface circuits.
For engineers reviewing the 1.5KE62-E3/73 datasheet, 1.5KE62-E3/73 pinout, 1.5KE62-E3/73 application, or 1.5KE62-E3/73 equivalent, this page delivers verified electrical parameters, JEDEC-standard 1.5KE package details, thermal derating behavior, clamping performance under surge conditions, and direct alternatives for ESD/lightning transient protection design.
Technical Context
The 1.5KE62-E3/73 uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables cathode-referenced placement on positive-rail protection paths, with a maximum reverse standoff voltage (VWM) of 53.0 V and leakage current ≤1.0 µA at that voltage.
It complies with JEDEC standard test waveforms (10/1000 µs pulse, 0.01% duty cycle), supports 200 A non-repetitive forward surge current (8.3 ms half-sine), and exhibits a temperature coefficient of VBR of +0.104 %/°C - critical for stable clamping across wide ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1.0 mA - defines reliable conduction onset threshold under transient stress |
| VWM | 53.0 V - maximum continuous DC operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 85.0 V at 17.6 A - clamped voltage during full 1500 W surge, limiting downstream IC stress |
| PPPM | 1500 W (10/1000 µs waveform) - peak transient energy absorption capacity per pulse |
| TJ range | –55 °C to +175 °C - enables use in under-hood automotive and high-temp industrial environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, informs heatsinking requirements |
| Package | DO-201AD (JEDEC 1.5KE) - axial-leaded, epoxy-molded, UL 94 V-0 rated case |
Pinout & Package
1.5KE62-E3/73 is housed in a DO-201AD (Case Style 1.5KE) axial-leaded package with matte tin-plated leads. The cathode is marked by a color band on the body; no marking is present on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for unidirectional clamping | Connected to ground or low-side return path; conducts when cathode-to-anode voltage exceeds VBR |
| Cathode | Protected line connection point | Connected to the line being protected (e.g., +12 V rail); color-banded end indicates polarity |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance and long-term reliability under thermal cycling and humidity |
| 1500 W peak pulse rating | Withstands lightning-induced surges (IEC 61000-4-5 Level 4) without degradation |
| Sub-nanosecond response time | Clamps transients before sensitive ICs experience overstress - critical for MOSFET gate protection |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance, suitable for lead-free reflow and wave soldering |
| UL 94 V-0 molding compound | Provides flame-retardant encapsulation for safety-critical automotive and industrial applications |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
|

Use Value: Clamps 8 kV contact ESD (IEC 61000-4-2) within <1 ns, preserving analog accuracy and avoiding latch-up. |
| Telecom DC Power Feeds | Consumer Power Adapter Outputs |
|
Use Scenario: Safeguarding PoE-powered equipment (IEEE 802.3af/at) from induced surges on 48 V DC distribution lines. IC Role / Device Role: Standoff-rated TVS on the powered device's input stage, upstream of DC-DC converter.

IC Role / Device Role: Final-stage TVS on regulated 20 V output rail to absorb flyback spikes and hot-plug transients. Use Value: Delivers 85.0 V clamping at 17.6 A, ensuring downstream USB-PD controllers remain below absolute max ratings. |
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 SMAJ60A | DO-214AC (SMA) package; lower PPPM = 400 W; VBR = 66.7–73.7 V; VC = 96.8 V @ 4.1 A | Lower surge capacity suits consumer-grade, non-automotive designs with less stringent IEC 61000-4-5 requirements | Select when board space is constrained and peak surge energy is ≤400 W; not drop-in due to different package and thermal profile |
| ON Semiconductor 1.5SMC62A | DO-214AB (SMC) package; same PPPM = 1500 W; VBR = 65.1–72.0 V; VC = 100 V @ 15 A; RθJA = 19 °C/W (surface-mount) | Surface-mount form factor enables automated assembly; higher VC increases stress on protected circuitry | Choose for SMT production and thermal management via PCB copper; verify layout clearance for 100 V clamping margin |
Compared with 1.5KE62-E3/73, SMAJ60A offers smaller footprint but reduced surge handling, while 1.5SMC62A matches power rating in SMT format at the cost of higher clamping voltage and different thermal path - both require redesign for mechanical fit and layout.

FAQ
What is the breakdown voltage tolerance of the 1.5KE62-E3/73?
The 1.5KE62-E3/73 has a specified breakdown voltage range of 58.9 V to 65.1 V at 1.0 mA test current, corresponding to ±10% tolerance around the nominal 62 V rating. This tolerance is confirmed in Vishay's official datasheet (Document Number: 88301, Rev. 09-Aug-2022) and applies under standard test conditions at TA = 25 °C. The 1.5KE62-E3/73 maintains this specification across its qualified operating temperature range.
Is the 1.5KE62-E3/73 RoHS compliant and lead-free?
Yes, the 1.5KE62-E3/73 carries the "E3" suffix, indicating full RoHS compliance per EU Directive 2011/65/EU and exemption 6(c)-I. Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and it passes JESD 201 Class 1A whisker testing. The 1.5KE62-E3/73 is rated for lead-free reflow profiles up to 260 °C peak and solder dip at 275 °C for 10 seconds.
Can the 1.5KE62-E3/73 be used in bidirectional configurations?
No, the 1.5KE62-E3/73 is a unidirectional TVS diode, as indicated by the absence of "CA" in its part number. Bidirectional variants in the 1.5KE family use the "CA" suffix (e.g., 1.5KE62CA) and are only offered up to 220 V VBR. The 1.5KE62-E3/73 must be oriented with its cathode toward the protected line and anode to ground; reverse connection will cause forward conduction and failure under normal bias.
What is the maximum clamping voltage of the 1.5KE62-E3/73 under surge conditions?
The 1.5KE62-E3/73 clamps to a maximum of 85.0 V when subjected to its rated peak pulse current of 17.6 A (10/1000 µs waveform). This value is measured per JEDEC standard test conditions and represents the upper limit of voltage seen by downstream circuitry during a full 1500 W transient event. The 1.5KE62-E3/73 achieves this with low incremental surge resistance, ensuring consistent clamping across multiple pulses.
Does the 1.5KE62-E3/73 meet AEC-Q101 qualification?
No, the 1.5KE62-E3/73 is a commercial-grade device. AEC-Q101 qualification is reserved for variants bearing the "HE3" suffix (e.g., 1.5KE62AHE3_B), which undergo additional stress testing for automotive applications. The 1.5KE62-E3/73 meets all electrical and mechanical specifications in the Vishay 1.5KE family datasheet but lacks the extended temperature cycling, HTRB, and ESD validation required for AEC-Q101. For automotive use, specify the HE3 variant.
