Product details
Overview
1.5KE82C-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 77.9 V to 86.1 V breakdown voltage (VBR), 70.1 V standoff voltage (VWM), 113 V clamping voltage at 13.3 A peak pulse current, 1500 W peak pulse power (10/1000 μs), and operates across -55 °C to +175 °C junction temperature range - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5KE82C-E3/54 datasheet, 1.5KE82C-E3/54 pinout, 1.5KE82C-E3/54 application, or 1.5KE82C-E3/54 equivalent, this page delivers verified electrical specs, JEDEC-standard case 1.5KE package details, clamping behavior under transient stress, thermal derating curves, and direct-fit alternatives for ESD/lightning surge hardening in 24 V DC systems.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction optimized for sub-nanosecond response (<1 ns) and low incremental surge resistance. Its symmetrical clamping characteristic applies equally in both polarities, with no cathode marking on the epoxy body.
It delivers 1500 W peak pulse power per 10/1000 μs waveform at TA = 25 °C, derating linearly above 25 °C per Fig. 2, and supports repetitive surge duty cycles up to 0.01 %. The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 1A whisker testing (E3 suffix).

Use Scenario: Safeguarding 4–20 mA current loop inputs in programmable logic controllers against field wiring surges and ESD events. IC Role / Device Role / Timing Role: Standoff-and-clamp protector mounted directly at terminal block entry point to shunt induced energy away from precision op-amps and ADC front-ends. Use Value: Withstands 13.3 A peak current and maintains 70.1 V working voltage margin, enabling robust operation in factory-floor environments with frequent cable hot-plugging. |
| Telecom Power Feeds | Consumer Appliance Motor Drivers |
Use Scenario: Surge suppression on -48 V DC power feeds in remote radio units and base station backhaul equipment. IC Role / Device Role / Timing Role: Primary overvoltage clamp on DC input rails, coordinated with upstream fuses and secondary filtering to meet GR-1089-CORE requirements. Use Value: 1500 W pulse rating and 175 °C max junction temperature allow sustained operation in sealed, high-ambient enclosures without thermal runaway. |
Use Scenario: Input-stage protection for BLDC motor driver boards in washing machines and HVAC blowers exposed to inductive kickback. IC Role / Device Role / Timing Role: Fast-acting snubber across bridge rectifier outputs or DC bus to absorb flyback energy from relay coils and motor windings. Use Value: Low clamping ratio (VC/VBR ≈ 1.44) minimizes voltage overshoot during commutation, reducing stress on 600 V IGBTs and improving system reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85CA | DO-214AA package; lower 600 W PPPM; 85 V VBR (min 80.8 V); 134 V VC @ 4.5 A. | Surface-mount only; suited for space-constrained PCBs but requires layout redesign and lacks axial lead thermal mass. | Select when board real estate is limited and 600 W surge margin suffices for IEC 61000-4-5 Level 2 compliance. |
| 1.5KE82CA | Same 1.5KE package and electrical specs, but without E3 suffix - non-RoHS, commercial grade only, no JESD 201 whisker test. | No AEC-Q101 or RoHS compliance; unsuitable for automotive or regulated industrial deployments. | Choose only for legacy cost-sensitive consumer applications where environmental compliance is not mandated. |
Compared with 1.5KE82C-E3/54, SMBJ85CA trades peak power and thermal robustness for SMT compatibility, while 1.5KE82CA sacrifices regulatory compliance for marginal cost reduction - neither offers pin-compatible replacement without requalification.

FAQ
What is the clamping voltage of the 1.5KE82C-E3/54 under a 10/1000 μs surge?
The 1.5KE82C-E3/54 clamps to a maximum of 113 V at its rated peak pulse current of 13.3 A under a 10/1000 μs waveform. This value is measured per JEDEC standard test conditions and reflects the actual voltage seen by downstream circuitry during surge events - critical for ensuring connected ICs remain within absolute maximum ratings. The 1.5KE82C-E3/54 achieves this with minimal voltage overshoot due to its low incremental surge resistance.
Is the 1.5KE82C-E3/54 RoHS compliant and qualified for automotive use?
The 1.5KE82C-E3/54 carries the E3 suffix, confirming RoHS compliance per EU Directive 2011/65/EU and passing JESD 201 Class 1A whisker testing. However, it is not AEC-Q101 qualified - that designation applies only to variants with HE3 suffix (e.g., 1.5KE82CAHE3_B). For automotive applications requiring AEC-Q101, the 1.5KE82C-E3/54 must be replaced with an HE3-suffixed part; the 1.5KE82C-E3/54 remains suitable for commercial and industrial deployments.
How does the bidirectional nature of the 1.5KE82C-E3/54 affect PCB layout?
The 1.5KE82C-E3/54 has no polarity marking and functions identically in either direction, eliminating orientation constraints during placement. This simplifies assembly and avoids misorientation risk in high-volume manufacturing. Layout requires only symmetric trace routing to both leads, with adequate copper pour for thermal dissipation - unlike unidirectional TVS diodes, no cathode alignment or directional routing rules apply to the 1.5KE82C-E3/54.
What is the maximum operating temperature for the 1.5KE82C-E3/54?
The 1.5KE82C-E3/54 has a specified junction temperature range of -55 °C to +175 °C, with thermal resistance from junction to lead (RθJL) of 15.4 °C/W. At ambient temperatures up to 125 °C, the device sustains full 1500 W pulse rating when properly heatsinked via leads - making it suitable for under-hood automotive modules and industrial motor drive cabinets where ambient heat buildup is significant. Derating begins above TA = 25 °C per Fig. 2 in the datasheet.
Can the 1.5KE82C-E3/54 be used in parallel to increase surge current handling?
Yes - the 1.5KE82C-E3/54 may be paralleled to increase total peak pulse current capacity, provided matched devices are used and layout ensures equal current sharing (e.g., symmetrical trace lengths and shared thermal plane). However, due to VBR tolerance (±5 %), slight imbalance may occur; for critical applications, current-sharing resistors or fused parallel paths are recommended. The 1.5KE82C-E3/54's glass-passivated junction ensures stable matching across lots.
