Product details
Overview
1.5KE62HE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary overvoltage protection in power rails and signal lines. It features a 58.9 V to 65.1 V breakdown voltage (VBR), 53.0 V standoff voltage (VWM), 85.0 V clamping voltage (VC) at 17.6 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across -55 °C to +175 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5KE62HE3/54 datasheet, 1.5KE62HE3/54 pinout, 1.5KE62HE3/54 application, or 1.5KE62HE3/54 equivalent, this device is selected for high-energy surge immunity in automotive power supplies, industrial I/O modules, and telecom line cards where fast clamping (<1 ns), low incremental surge resistance, and AEC-Q101 qualification are required.
Technical Context
The 1.5KE62HE3/54 implements a glass-passivated silicon PN junction optimized for transient suppression under 10/1000 µs waveform conditions. Its unidirectional polarity enables cathode-referenced placement on DC rails, with clamping action triggered when reverse voltage exceeds VBR (min 58.9 V, max 65.1 V at 1.0 mA test current).
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15.4 °C/W, supporting operation up to 175 °C junction temperature. The device meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability requirements, with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1.0 mA - defines precise voltage threshold for avalanche conduction onset |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 85.0 V at 17.6 A - clamped voltage during 1500 W transient, limiting stress on downstream components |
| PPPM | 1500 W (10/1000 µs) - peak surge energy handling capacity for standardized lightning/surge testing |
| IFSM | 200 A (8.3 ms half-sine) - forward surge rating for unidirectional configuration only |
| TJ range | -55 °C to +175 °C - enables deployment in under-hood automotive and industrial environments |

Pinout & Package
1.5KE62HE3/54 uses the standard DO-201AD (Case Style 1.5KE) axial-leaded package. The cathode is marked by a color band on the body; no marking is present on bidirectional variants. Leads are matte tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / reverse voltage reference | Connected to lower-potential side of protected circuit; determines unidirectional conduction path |
| Cathode | Avalanche conduction node / clamping output | Marked end; connected to higher-potential rail (e.g., VCC) to clamp transients to ground-referenced path |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A-E3/52 | DO-214AA package (SMB), 64 V VBR, 1000 W PPPM, 70 V VC @ 14.3 A | Lower power rating and smaller footprint; suited for space-constrained consumer designs | Select SMBJ64A-E3/52 when board area is limited and 1000 W surge immunity suffices; not AEC-Q101 qualified. |
| 1.5KE62A-E3/54 | Same 1.5KE package and electrical specs, but commercial-grade (non-AEC-Q101) | Lacks automotive qualification; suitable for industrial/commercial power supplies without automotive lifecycle requirements | Choose 1.5KE62A-E3/54 for cost-sensitive non-automotive applications where AEC-Q101 is not mandated. |
Compared with 1.5KE62HE3/54, SMBJ64A-E3/52 offers reduced surge capacity and no automotive qualification but saves PCB area, while 1.5KE62A-E3/54 matches all electrical parameters but omits AEC-Q101 validation-making it appropriate only for non-automotive use cases.

FAQ
What is the breakdown voltage tolerance for 1.5KE62HE3/54?
The 1.5KE62HE3/54 has a specified breakdown voltage range of 58.9 V to 65.1 V at 1.0 mA test current, representing ±5% tolerance around the nominal 62 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports reliable design margining in 12 V and 24 V systems.
Is 1.5KE62HE3/54 suitable for bidirectional surge protection?
No, 1.5KE62HE3/54 is a unidirectional TVS diode, indicated by the absence of "CA" suffix. Bidirectional variants (e.g., 1.5KE62CA) exist in the same family but are distinct part numbers. Using 1.5KE62HE3/54 in AC or floating applications would result in forward conduction during negative half-cycles and potential failure.
Does 1.5KE62HE3/54 require a heatsink for 1500 W surge handling?
No external heatsink is required for single-event 1500 W surges (10/1000 µs), as energy dissipation occurs too rapidly for thermal accumulation. However, the device's RθJA = 75 °C/W and RθJL = 15.4 °C/W mean sustained power or repetitive pulses demand careful PCB copper area design-especially given its 175 °C max junction temperature rating.
How does the HE3 suffix affect 1.5KE62HE3/54 compared to standard E3?
HE3 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. Standard E3 parts (e.g., 1.5KE62A-E3/54) share identical electrical specs and RoHS status but lack automotive qualification and Class 2 whisker testing-making HE3 mandatory for automotive applications.
What is the maximum reverse leakage current for 1.5KE62HE3/54 at rated standoff voltage?
At its 53.0 V standoff voltage (VWM), the 1.5KE62HE3/54 exhibits a maximum reverse leakage current of 1.0 µA at 25 °C. This ultra-low leakage preserves efficiency in always-on power rails and avoids false triggering in high-impedance sensing circuits, directly supporting low-power automotive and industrial monitoring systems.
