Product details
Overview
1.5KE62CA-E3/51 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power 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. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients in industrial and automotive systems.
For engineers reviewing the 1.5KE62CA-E3/51 datasheet, 1.5KE62CA-E3/51 pinout, 1.5KE62CA-E3/51 application, or 1.5KE62CA-E3/51 equivalent, this page delivers verified electrical parameters, JEDEC-standardized package dimensions, bidirectional clamping behavior, thermal derating curves, and direct alternatives with documented parameter differences - all aligned to Vishay Document #88301 (Rev. 09-Aug-2022).
Technical Context
This device implements a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in both polarities without external polarity management, making it suitable for AC-coupled or floating signal paths.
It complies with JEDEC standards for surge testing (8.3 ms half-sine, 10/1000 µs waveform) and supports repetitive surge duty cycles up to 0.01 %. The 1.5KE package provides RθJA = 75 °C/W and RθJL = 15.4 °C/W, enabling reliable operation under high ambient temperatures when mounted on PCB copper pours or heatsinked leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at IT = 1 mA - defines precise clamping onset threshold for bidirectional overvoltage events |
| VWM | 53.0 V - maximum continuous working voltage before leakage exceeds 1 µA; sets safe operating margin below breakdown |
| VC @ IPPM | 85.0 V at 17.6 A - actual clamped voltage during 1500 W transient, limiting downstream stress on protected components |
| PPPM | 1500 W (10/1000 µs) - peak surge energy handling capacity, validated per REA and ANSI/IEEE C62.35 standards |
| IPPM | 17.6 A - peak pulse current capability directly derived from VC and PPPM; critical for layout trace sizing |
| TJ range | –55 °C to +175 °C - extended junction temperature rating enables use in under-hood automotive and industrial power supplies |
| Leakage @ VWM | 1.0 µA max - ultra-low reverse leakage preserves signal integrity and minimizes standby power loss |
Pinout & Package
Package: DO-201AD (JEDEC Case Style 1.5KE), molded epoxy body with matte tin-plated leads; RoHS-compliant (E3 suffix), UL 94 V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (bidirectional) | Non-polarized terminals | No marking; symmetric conduction in both directions - installed without orientation concern in AC or floating circuits |
Key Features
| Feature | Design Value |
|---|---|

| Clamping response time < 1 ns | Protects nanosecond-scale logic and high-speed interface ICs before damaging voltage overshoot occurs |
| Low incremental surge resistance | Minimizes VC rise under high di/dt transients - critical for protecting low-voltage MOSFET gates and precision analog inputs |
| AEC-Q101 qualified option available | HE3 variant (e.g., 1.5KE62CAHE3_B) meets automotive qualification for engine control and ADAS power rails |
Applications
| Industrial Motor Drives | Automotive Power Distribution |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower PPPM = 600 W; smaller SMB package (RθJA = 110 °C/W); VC = 104 V @ 5.8 A | Better suited for space-constrained consumer electronics where 1500 W is not required | Select when board area is limited and surge threat level is IEC 61000-4-5 Level 2–3 only |
| 1.5SMC68CA | Same 1500 W rating but SMC package (RθJA = 85 °C/W); VBR = 64.6–71.4 V; VC = 110 V @ 13.7 A | Higher clamping voltage reduces protection margin for 5 V/3.3 V circuitry | Choose only if DO-201AD footprint is unavailable and thermal design accommodates higher RθJA |
Compared with 1.5KE62CA-E3/51, SMBJ64CA trades peak power and thermal robustness for compact size, while 1.5SMC68CA maintains power rating but sacrifices clamping tightness and thermal efficiency - making 1.5KE62CA-E3/51 optimal for high-reliability 24–48 V industrial and automotive rails where low VC and proven DO-201AD mounting are essential.

FAQ
What is the exact breakdown voltage range for 1.5KE62CA-E3/51?
The 1.5KE62CA-E3/51 has a guaranteed breakdown voltage (VBR) range of 58.9 V to 65.1 V at a test current of 1 mA, per Vishay Document #88301. This specification applies in both directions due to its bidirectional construction, and the tolerance is maintained across the full operating temperature range (–55 °C to +175 °C). No extrapolation or interpolation is required - these values are measured and binned during production.
Is 1.5KE62CA-E3/51 RoHS compliant and lead-free?
Yes, the "E3" suffix in 1.5KE62CA-E3/51 explicitly denotes RoHS compliance and commercial-grade qualification per JESD 201 Class 1A whisker testing. The matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability requirements, and the molded epoxy body complies with UL 94 V-0 flammability standards. No lead or halogen exemptions apply.
Does 1.5KE62CA-E3/51 have AEC-Q101 qualification?
The base 1.5KE62CA-E3/51 is not AEC-Q101 qualified; however, the variant 1.5KE62CAHE3_B is fully AEC-Q101 qualified per Note (2) in Document #88301. That version shares identical electrical specs and DO-201AD packaging but adds automotive-grade screening, including temperature cycling, HTRB, and ESD testing. For automotive designs, specify the HE3_B suffix.
What is the maximum clamping voltage of 1.5KE62CA-E3/51 under surge conditions?
The maximum clamping voltage (VC) of 1.5KE62CA-E3/51 is 85.0 V at a peak pulse current (IPPM) of 17.6 A, tested with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and represents the worst-case voltage seen by downstream components during a full-rated 1500 W transient event - critical for validating safe operating margins of protected ICs.
Can 1.5KE62CA-E3/51 be used in AC line protection applications?
Yes - the bidirectional nature of 1.5KE62CA-E3/51 makes it suitable for AC-coupled protection, such as across secondary windings of isolation transformers or on differential signal pairs. Its symmetrical VBR and VC ensure equal clamping in both half-cycles. However, it must be applied downstream of AC/DC rectification for primary-side mains protection, as its 62 V rating is insufficient for direct 120/230 VAC line connection.
