Product details
Overview
1.5KE62CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary 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 used to protect MOSFETs, ICs, and sensor interfaces against inductive switching transients and ESD in industrial power supplies.
For engineers reviewing the 1.5KE62CHE3/54 datasheet, 1.5KE62CHE3/54 pinout, 1.5KE62CHE3/54 application, or 1.5KE62CHE3/54 equivalent, this page delivers verified electrical specs, thermal derating behavior, clamping performance under surge, RoHS-compliant packaging (E3 suffix), and AEC-Q101-qualified alternatives - all critical for automotive-grade transient protection design and BOM validation.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables cathode-referenced clamping on positive-going transients, with a maximum reverse standoff voltage (VWM) of 53.0 V and leakage current ≤1.0 µA at that voltage.
The device sustains 200 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits a temperature coefficient of VBR of +0.104 %/°C. Thermal resistance is 15.4 °C/W (junction-to-lead), enabling effective heat dissipation through PCB copper when mounted with ≥9.5 mm lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1.0 mA - defines precise clamping onset threshold for overvoltage detection |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 85.0 V at 17.6 A - peak clamped voltage during 10/1000 µs surge, limiting stress on downstream components |
| PPPM | 1500 W - peak pulse power handling capability, supporting robust protection against lightning-induced surges |
| IFSM | 200 A - surge current rating (8.3 ms half-sine), validating suitability for high-energy inductive load switching |
| TJ range | –55 °C to +175 °C - wide operating junction temperature, enabling use in under-hood automotive and industrial environments |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance, allowing efficient heat transfer to PCB traces or heatsinks |
Pinout & Package
Package: DO-201AD (Case Style 1.5KE), axial-leaded, molded epoxy body meeting UL 94 V-0. Matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards. E3 suffix indicates RoHS compliance and JESD 201 Class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or low-side reference; conducts during positive transients when cathode is biased above anode |
| Cathode | Reverse-biased clamping terminal | Marked with color band; connected to protected line; clamps voltage by avalanching when line exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| 1500 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) without external series impedance |
| Clamping ratio VC/VBR ≈ 1.33 | Minimizes overvoltage overshoot during fast transients, reducing risk of latch-up or gate oxide damage in protected ICs |
| AEC-Q101 qualified variant available | Validates robustness for automotive applications including engine control modules and body electronics |
| Low incremental surge resistance | Reduces dynamic voltage rise during high di/dt events, improving protection fidelity for fast-rising ESD or switching spikes |
Applications

IC Role / Device Role / Timing Role: Low-leakage (≤1 µA) TVS shunting input pins to ground during field-wiring faults. Use Value: Maintains <53 V standoff while adding <1 pF capacitance, avoiding gain error or bandwidth degradation in precision amplifiers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | DO-214AA package, 64 V VBR, 600 W PPPM, higher VC/VBR ratio (1.43) | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 4 without parallel staging | Select when board space is constrained and surge requirements are ≤600 W; verify thermal margin at 15.4 °C/W vs. SMBJ's 40 °C/W RθJA |
| 1.5KE62AHE3_B | Identical electrical specs; HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance | Approved for automotive under-hood use per AEC-Q101; commercial-grade 1.5KE62CHE3/54 lacks qualification documentation | Choose for automotive OEM programs requiring certified reliability; otherwise, 1.5KE62CHE3/54 suffices for industrial/commercial designs |
Compared with 1.5KE62CHE3/54, SMBJ64A offers smaller footprint but only 40% of the surge power handling, while 1.5KE62AHE3_B provides identical protection performance plus automotive qualification - making it a drop-in upgrade where AEC-Q101 compliance is mandatory.

FAQ
What is the clamping voltage of the 1.5KE62CHE3/54 under a 10/1000 µs surge?
The 1.5KE62CHE3/54 clamps to a maximum of 85.0 V at 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 protected circuitry during a full-power transient event. The actual clamping voltage of the 1.5KE62CHE3/54 will be lower at reduced surge currents, following the device's incremental clamping curve.
Is the 1.5KE62CHE3/54 RoHS compliant and lead-free?
Yes, the 1.5KE62CHE3/54 carries the E3 suffix, which certifies full RoHS compliance per Directive 2011/65/EU and JESD 201 Class 1A whisker resistance. Its matte tin-plated leads are lead-free and solderable per J-STD-002 and JESD 22-B102. No lead or hazardous substances exceeding EU limits are present in the 1.5KE62CHE3/54 construction or plating.
Can the 1.5KE62CHE3/54 be used in bidirectional protection circuits?
No - the 1.5KE62CHE3/54 is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). It clamps only positive transients relative to its cathode. For bidirectional protection, Vishay specifies part numbers ending in "CA", such as 1.5KE62CA; the 1.5KE62CHE3/54 must be paired with a second diode or replaced entirely to achieve symmetrical clamping.
What is the maximum operating temperature for the 1.5KE62CHE3/54?
The 1.5KE62CHE3/54 has a specified junction temperature range of –55 °C to +175 °C. Its maximum steady-state power dissipation is 6.5 W at TL = 75 °C (lead temperature), derating linearly above that point. At ambient temperatures up to +125 °C, the 1.5KE62CHE3/54 remains functional provided thermal design maintains TJ ≤ 175 °C using its 15.4 °C/W junction-to-lead resistance.
How does the 1.5KE62CHE3/54 compare to the 1.5KE62A in terms of packaging and marking?
The 1.5KE62CHE3/54 uses the same DO-201AD package and electrical specifications as the base 1.5KE62A, but adds the E3 suffix indicating RoHS compliance and JESD 201 Class 1A whisker resistance. The "/54" denotes packaging in 13″ paper tape and reel with 1400 units per reel. Visually, both share the same axial body and cathode band marking; no functional difference exists beyond environmental compliance and packaging format.
