Product details
Overview
1.5SMC82CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, designed for high-energy surge protection. It features a 82 V breakdown voltage (VBR = 77.9–86.1 V at IT = 1 mA), 113 V maximum clamping voltage (VC) at 13.3 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to protect automotive sensor signal lines, industrial I/O ports, and telecom interface circuits against lightning-induced transients and inductive switching spikes.
For engineers reviewing the 1.5SMC82CAHE3_A/H datasheet, 1.5SMC82CAHE3_A/H pinout, 1.5SMC82CAHE3_A/H application, or 1.5SMC82CAHE3_A/H equivalent, this device is selected for robust bidirectional clamping in AEC-Q101-qualified automotive systems, where low incremental surge resistance, fast response time (<1 ns), and MSL Level 1 moisture sensitivity are critical design requirements.
Technical Context
The 1.5SMC82CAHE3_A/H operates as a bidirectional avalanche diode, symmetrically clamping voltage surges above ±82 V in either polarity without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM = 70.1 V), while its thermal resistance (RθJA = 75 °C/W) supports operation up to TJ = 150 °C under derated conditions.
It delivers 13.3 A peak pulse current (IPPM) at 113 V clamping with 10/1000 µs waveform, maintaining <0.105 %/°C temperature coefficient of VBR. The device meets JESD201 Class 2 whisker resistance and is qualified to AEC-Q101 for automotive use - confirmed by HE3 suffix and "_A" revision code per ordering table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 77.9 V / 86.1 V at IT = 1 mA - defines precise bidirectional avalanche onset threshold for reliable overvoltage triggering |
| VWM | 70.1 V - maximum continuous reverse stand-off voltage before leakage exceeds 1 µA, ensuring no false triggering in normal operation |
| VC @ IPPM | 113 V at 13.3 A - clamping voltage during 10/1000 µs surge, limiting downstream IC stress to safe levels |
| PPPM | 1500 W - peak pulse power handling capability, enabling protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) |
| TJ max. | +150 °C - maximum junction temperature, supporting under-hood automotive deployment with appropriate PCB copper area |
| Package | SMC (DO-214AB) - standardized surface-mount outline with 8.0 mm × 8.0 mm copper pads for thermal dissipation and automated placement compatibility |
| AEC-Q101 | Qualified - validated for automotive reliability including temperature cycling, HTRB, and ESD per AEC standard, enabled by HE3 suffix |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL Level 1 (260 °C peak reflow). Bidirectional configuration has no polarity marking; both terminals are electrically symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Electrically identical to Terminal 2; forms symmetrical clamping path across protected line and ground or differential pair |
| Terminal 2 | Anode/Cathode (bidirectional) | Paired terminal enabling bidirectional transient suppression without orientation dependency during placement |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional 1500 W surge rating | Clamps ±113 V at 13.3 A (10/1000 µs), protecting RS-485, CAN, and LIN bus lines from asymmetrical transients |
| AEC-Q101 qualification (HE3 suffix) | Validated for automotive-grade reliability including 1000-cycle temperature cycling and 1000-hour HTRB at 150 °C |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes let-through energy to sensitive receivers, reducing need for secondary filtering in cost-sensitive ECUs |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow assembly without baking or special handling in high-volume automotive PCB production |
| Glass-passivated junction | Ensures stable VBR tolerance (±5%) and <1 µA leakage at VWM, critical for low-power always-on sensor interfaces |
Applications
| Automotive Sensor Protection | Industrial I/O Port Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85CA | Lower PPPM (600 W), higher VC (137 V at 4.4 A), SMB package (smaller thermal mass) | Limited to lower-energy surges (IEC 61000-4-5 Level 2); unsuitable for automotive under-hood locations requiring 1500 W rating | Select when board space is constrained and surge threat level is ≤1 kV/42 Ω, not for AEC-Q101-critical designs |
| 1.5KE82CA | Through-hole DO-201 package, same VBR/VC, but slower thermal response and no AEC-Q101 qualification | Not suitable for automated SMT lines or automotive vibration environments; lacks MSL Level 1 reflow compatibility | Choose only for legacy through-hole prototyping or non-automotive industrial repairs where SMT is unavailable |
Compared with SMBJ85CA and 1.5KE82CA, the 1.5SMC82CAHE3_A/H uniquely combines AEC-Q101 qualification, 1500 W surge rating in SMC package, and MSL Level 1 process compatibility - making it the only option among the three for new automotive electronics requiring zero-layout-change migration from legacy TVS solutions.

FAQ
What is the clamping voltage of the 1.5SMC82CAHE3_A/H under a 10/1000 µs surge?
The 1.5SMC82CAHE3_A/H clamps to a maximum of 113 V when subjected to its rated 13.3 A peak pulse current with a 10/1000 µs waveform. This value is guaranteed across temperature and lifetime per Vishay's 88303 datasheet, and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 1.5SMC82CAHE3_A/H suitable for automotive applications?
Yes - the 1.5SMC82CAHE3_A/H carries the HE3 suffix and "_A" revision code, confirming AEC-Q101 qualification per Vishay's ordering table. It is explicitly rated for automotive under-hood and cabin applications, including engine control, body electronics, and ADAS sensor interfaces requiring robust transient immunity.
What does the "CA" suffix indicate in 1.5SMC82CAHE3_A/H?
The "CA" suffix denotes a bidirectional configuration: the 1.5SMC82CAHE3_A/H provides symmetrical clamping for both positive and negative transients, with identical VBR, VC, and IPPM characteristics in either polarity - essential for protecting AC-coupled or differential signal paths like CAN or RS-485.
What is the maximum operating junction temperature for the 1.5SMC82CAHE3_A/H?
The 1.5SMC82CAHE3_A/H has a maximum junction temperature (TJ) of +150 °C, as specified in the Absolute Maximum Ratings table. Derating curves in Figure 2 show usable power decreases linearly above 25 °C ambient, requiring ≥8.0 mm × 8.0 mm copper pad area per terminal for full 1500 W rating at elevated temperatures.
How does the 1.5SMC82CAHE3_A/H differ from unidirectional variants like 1.5SMC82AHE3_A/H?
Unlike unidirectional 1.5SMC82AHE3_A/H, the 1.5SMC82CAHE3_A/H has no cathode band marking and exhibits identical electrical behavior in both directions - VBR, VC, and leakage are matched for positive and negative surges. This eliminates orientation concerns during SMT placement and enables protection of floating or AC-signaled lines.
