Overview
1.5KE82CHE3/73 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 77.9 V to 86.1 V breakdown voltage (VBR), 70.1 V maximum working peak reverse voltage (VWM), 113 V clamping voltage at 13.3 A peak pulse current, 1500 W peak pulse power rating (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the 1.5KE82CHE3/73 datasheet, 1.5KE82CHE3/73 pinout, 1.5KE82CHE3/73 application, or 1.5KE82CHE3/73 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping behavior under surge conditions, thermal derating guidance, and AEC-Q101-qualified alternatives for automotive-grade design validation.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables cathode-referenced clamping on positive-going transients, with a 3.5 V forward voltage at 100 A per JEDEC spec - critical for minimizing conduction loss during high-current surges.
The device complies with UL 497B recognition (QVGQ2) and meets JESD 201 Class 1A whisker resistance (E3 suffix). It is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits a +0.105 %/°C temperature coefficient of VBR, ensuring predictable voltage threshold drift across operating temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85A-E3/52 | DO-214AA package; lower 85 V VBR (80.8–89.2 V); 600 W PPPM; 10.5 A IPPM | Surface-mount alternative for space-constrained designs; not AEC-Q101 qualified in base E3 version | Select when board area is limited and 600 W surge rating suffices; verify layout thermal relief for SMB footprint. |
| 1.5KE82CAHE3_B | Bidirectional variant; same VBR range (77.9–86.1 V); identical PPPM/VC; no polarity marking | Required for AC-coupled or bidirectional signal lines (e.g., RS-485, CAN bus) where negative transients must also be clamped | Choose only if protecting symmetric differential signals; note that unidirectional 1.5KE82CHE3/73 cannot substitute in bidirectional roles. |
Compared with 1.5KE82CHE3/73, SMBJ85A-E3/52 offers smaller footprint but reduced surge capacity and no AEC-Q101 qualification, while 1.5KE82CAHE3_B provides identical clamping performance for bidirectional threats - neither is pin-compatible due to differing polarity and package form factor.

FAQ
What is the breakdown voltage range specified for 1.5KE82CHE3/73?
The 1.5KE82CHE3/73 has a guaranteed breakdown voltage (VBR) range of 77.9 V to 86.1 V at 1 mA test current, per Vishay Document 88301. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable overvoltage margining in 70 V nominal systems. The value is measured under standardized JEDEC conditions and reflects the actual voltage at which the device transitions from high-impedance blocking to low-impedance conduction.
Is 1.5KE82CHE3/73 AEC-Q101 qualified?
No - 1.5KE82CHE3/73 carries the E3 suffix (RoHS-compliant commercial grade) but is not AEC-Q101 qualified. AEC-Q101 qualification applies only to variants with the HE3 suffix and revision code (e.g., 1.5KE82AHE3_B). For automotive applications requiring AEC-Q101 compliance, specify the HE3 variant explicitly; the 1.5KE82CHE3/73 remains suitable for industrial and consumer designs where automotive qualification is not mandated.
What is the clamping voltage of 1.5KE82CHE3/73 at its rated peak pulse current?
The clamping voltage (VC) of 1.5KE82CHE3/73 is 113 V at 13.3 A peak pulse current (IPPM) under a 10/1000 µs waveform, as confirmed in Vishay's 88301 datasheet Table on page 2. This value represents the maximum voltage seen by downstream circuitry during worst-case surge events and is critical for validating whether protected components remain within their absolute maximum ratings.
Can 1.5KE82CHE3/73 be used in bidirectional signal protection?
No - 1.5KE82CHE3/73 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. It clamps only positive transients relative to ground. For bidirectional protection (e.g., RS-485, CAN, AC lines), the "CA" variant - such as 1.5KE82CAHE3_B - must be used. Substituting 1.5KE82CHE3/73 in a bidirectional role leaves the circuit vulnerable to negative-going surges.
What package type does 1.5KE82CHE3/73 use, and what are its key mechanical features?
1.5KE82CHE3/73 uses the JEDEC DO-201AD package (Case Style 1.5KE): axial-leaded, epoxy-molded body with 0.375" (9.5 mm) lead length. Key features include UL 94 V-0 flammability rating, matte tin-plated leads compliant with J-STD-002, and JESD 201 Class 1A whisker resistance. The cathode is marked with a color band; no marking is present on bidirectional versions.
