Product details
Overview
1.5KE82CAHE3_B/C from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection on signal and power lines. It features a 77.9 V to 86.1 V breakdown voltage (VBR), 70.1 V standoff voltage (VWM), 113 V clamping voltage (VC) 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. It is used in automotive sensor interfaces and industrial I/O protection where fast clamping and high surge immunity are required.
For engineers reviewing the 1.5KE82CAHE3_B/C datasheet, 1.5KE82CAHE3_B/C pinout, 1.5KE82CAHE3_B/C application, or 1.5KE82CAHE3_B/C equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), RoHS-compliant HE3 packaging, and real-world use context for ESD/lightning transient suppression in bidirectional AC-coupled or floating lines.
Technical Context
This device implements a silicon avalanche junction structure optimized for sub-nanosecond response (<1 ns) to transient overvoltages, enabling effective protection of downstream MOSFETs, microcontrollers, and analog front-ends. Its bidirectional symmetry ensures identical clamping behavior in both polarities, with no polarity marking on the package.
The 1.5KE82CAHE3_B/C uses glass-passivated chip construction and molded epoxy encapsulation meeting UL 94 V-0. It supports repetitive 10/1000 µs surges at 0.01% duty cycle and is rated for 200 A non-repetitive forward surge (unidirectional only - not applicable here due to bidirectional configuration).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 77.9 V / 86.1 V - Ensures reliable avalanche conduction onset within tight tolerance for predictable clamping threshold |
| VWM | 70.1 V - Maximum continuous working voltage before leakage exceeds 1 µA; defines safe operating margin below breakdown |
| VC @ IPPM | 113 V at 13.3 A - Clamped voltage during 1500 W transient; determines maximum stress imposed on protected circuitry |
| PPPM | 1500 W (10/1000 µs) - Sustains high-energy lightning or inductive-switching transients without failure |
| Junction Temp Range | –55 °C to +175 °C - Enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment |
| Leakage @ VWM | 1 µA max - Minimizes standby power loss and avoids false triggering in low-power sensor circuits |
| Thermal Resistance | RθJL = 15.4 °C/W - Supports efficient heat transfer to PCB copper or heatsinked leads for sustained surge handling |

Applications
| Automotive Sensor Interface | Industrial Analog I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and temperature/pressure sensor signal lines from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional shunt clamp placed across differential pair or single-ended line to divert surge energy to ground. Use Value: Maintains signal integrity by limiting transient overshoot to ≤113 V while surviving repeated 10/1000 µs surges up to 1500 W. |
Use Scenario: Safeguarding 4–20 mA current loop inputs and ±10 V analog inputs in PLC modules against field-wiring induced transients. IC Role / Device Role / Timing Role: Standoff-mode protector mounted between input terminal and ground, conducting only during overvoltage events. Use Value: Enables compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) without adding series impedance or signal distortion. |
| Telecom Line Interface | AC Power Supply Input Stage |
Use Scenario: Secondary protection on DSL or Ethernet PHY lines exposed to induced lightning surges in rural deployments. IC Role / Device Role / Timing Role: Fast-acting secondary clamp following gas discharge tube (GDT) primary stage to limit let-through voltage. Use Value: Reduces residual clamping voltage to <113 V, preventing damage to PHY ICs rated for ≤120 V absolute maximum. |
Use Scenario: Bidirectional clamping across AC mains inputs (e.g., L–N or L/N–PE) in SMPS front-ends subject to switching transients. IC Role / Device Role / Timing Role: Voltage-limited shunt element that conducts only above 70.1 V, avoiding conduction during normal 230 VRMS operation. Use Value: Provides fail-safe overvoltage shutdown path without affecting efficiency or EMI performance during steady-state operation. |
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 | Lower PPPM (600 W), smaller SMB package (lower RθJA), VBR = 94.4–104.4 V | Better suited for space-constrained PCBs; less robust for high-energy 10/1000 µs surges | Select when board area is limited and surge threat level is ≤IEC 61000-4-5 Level 3 (2 kV) |
| 1.5KE82C | Same electrical specs but commercial-grade (non-AEC-Q101), E3 suffix only (no HE3), no whisker test certification | Acceptable for consumer or industrial non-automotive use; not qualified for automotive under-hood deployment | Choose for cost-sensitive non-automotive designs where AEC-Q101 and JESD201 Class 2 are not mandated |
Compared with 1.5KE82CAHE3_B/C, SMBJ85CA trades peak power and ruggedness for compactness, while 1.5KE82C retains identical clamping performance but omits automotive qualification and enhanced process controls - making the HE3 variant the sole choice for AEC-Q101–compliant systems requiring full traceability and extended temperature resilience.

FAQ
What does the "CA" suffix indicate in 1.5KE82CAHE3_B/C?
The "CA" suffix denotes a bidirectional configuration: the 1.5KE82CAHE3_B/C provides symmetrical clamping for both positive and negative transients, with identical VBR, VC, and IPPM characteristics in either polarity. Unlike unidirectional variants (e.g., 1.5KE82A), it has no cathode marking and is installed without orientation constraints - a key advantage for AC-coupled or floating signal paths.
Is 1.5KE82CAHE3_B/C qualified to AEC-Q101?
Yes, 1.5KE82CAHE3_B/C is explicitly AEC-Q101 qualified per Vishay documentation (Document 88301, Note 2). This includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and surge endurance - confirming suitability for automotive powertrain, body electronics, and ADAS sensor modules where reliability under thermal and electrical stress is mandatory.
What is the clamping voltage of 1.5KE82CAHE3_B/C at its rated peak pulse current?
The clamping voltage (VC) of 1.5KE82CAHE3_B/C is 113 V measured at its peak pulse current (IPPM) of 13.3 A under the standard 10/1000 µs waveform. This value defines the maximum voltage impressed on the protected circuit during a full-rated surge event and is critical for ensuring downstream components remain within their absolute maximum voltage ratings.
How does the HE3 suffix differ from the E3 suffix in 1.5KE82CAHE3_B/C?
The HE3 suffix in 1.5KE82CAHE3_B/C indicates RoHS compliance plus AEC-Q101 qualification and JESD201 Class 2 whisker resistance - exceeding the baseline E3 (RoHS + JESD201 Class 1A). The "H" prefix specifically denotes the automotive-grade process enhancement, including tighter parametric screening, extended temperature validation, and traceable lot control required for Tier 1 automotive supply chains.
Can 1.5KE82CAHE3_B/C be used in AC line protection applications?
Yes, 1.5KE82CAHE3_B/C is routinely deployed for AC line protection - particularly across L–N or L/N–PE in switch-mode power supplies. Its 70.1 V standoff voltage safely accommodates 230 VRMS (325 V peak) with margin, while its bidirectional nature ensures clamping during both half-cycles. Layout must minimize trace inductance to preserve sub-ns response and avoid voltage overshoot during fast transients.
