Product details
Overview
1.5SMC82CAHE3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 1500 W peak pulse power with 10/1000 μs waveform, 82 V breakdown voltage (VBR min/max = 77.9 V / 86.1 V), and clamping voltage of 113 V at 13.3 A peak pulse current. It protects sensitive signal lines in automotive sensor units and industrial control interfaces against lightning-induced transients and inductive switching surges.
For engineers reviewing the 1.5SMC82CAHE3/57T datasheet, 1.5SMC82CAHE3/57T pinout, 1.5SMC82CAHE3/57T application, or 1.5SMC82CAHE3/57T equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 113 V maximum clamping voltage at rated IPPM, and compatibility with automated SMT placement on standard PCB pad layouts per JEDEC DO-214AB footprint.
Technical Context
This device operates as a voltage-clamped surge protector: when reverse (or forward, in bidirectional mode) transient voltage exceeds its breakdown threshold (77.9–86.1 V), it avalanches to limit voltage across protected circuitry to ≤113 V. Its glass-passivated junction ensures stable leakage (<1.0 μA at 70.1 V stand-off) and fast response time (<1 ns).
Thermally, it features RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to TJ = 150 °C. The 1.5SMC82CAHE3/57T is qualified to AEC-Q101, confirming suitability for automotive environments including engine control modules and ADAS sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 77.9 V min / 86.1 V max at 1.0 mA test current - defines precise avalanche initiation range for repeatable clamping behavior |
| Stand-off Voltage VWM | 70.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA; sets safe DC bias margin |
| Peak Pulse Power PPPM | 1500 W (10/1000 μs waveform) - sustains high-energy transients without failure under defined surge conditions |
| Maximum Clamping Voltage VC | 113 V at 13.3 A IPPM - limits voltage seen by downstream ICs during worst-case surge events |
| Peak Pulse Current IPPM | 13.3 A - quantifies surge current handling capacity before clamping voltage exceeds specification |
| Operating Temperature Range | −65 °C to +150 °C - supports deployment in under-hood automotive and industrial ambient environments |

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), same 85 V nominal VBR, SMB (DO-214AA) package - smaller footprint but reduced surge margin | Preferred for space-constrained consumer designs where 600 W surge immunity suffices | Select when board area is critical and peak surge energy is ≤0.6 J; verify thermal derating for repeated pulses |
| 1.5KE82CA | Through-hole TO-204AE (DO-15) package, same 82 V VBR and 1500 W rating, higher RθJA (100 °C/W) | Used in legacy industrial power supplies requiring manual assembly or high-reliability through-hole mounting | Choose for repairability, high-vibration environments, or where SMT process validation is not available |
Compared with SMBJ85CA and 1.5KE82CA, the 1.5SMC82CAHE3/57T delivers identical clamping performance in a surface-mount AEC-Q101-qualified package optimized for automotive production, offering superior thermal dissipation (RθJL = 15 °C/W) and automated placement compatibility without sacrificing surge rating.

FAQ
What is the clamping voltage of the 1.5SMC82CAHE3/57T at its rated peak pulse current?
The 1.5SMC82CAHE3/57T has a maximum clamping voltage (VC) of 113 V at its rated peak pulse current (IPPM) of 13.3 A, measured using the standardized 10/1000 μs double-exponential waveform. This value ensures downstream ICs see no more than 113 V during worst-case surge events, protecting 5 V and 12 V logic interfaces.
Is the 1.5SMC82CAHE3/57T suitable for automotive applications?
Yes, the 1.5SMC82CAHE3/57T is AEC-Q101 qualified (indicated by the HE3 suffix), making it suitable for automotive applications including engine control units, ADAS sensors, and body electronics. It meets stress tests for temperature cycling, high-temperature reverse bias, and electrostatic discharge required for under-hood deployment.
What does the "CA" suffix mean in 1.5SMC82CAHE3/57T?
The "CA" suffix in 1.5SMC82CAHE3/57T denotes a bidirectional configuration: the device provides symmetrical transient suppression in both polarities, with identical breakdown and clamping characteristics for positive and negative surges. This eliminates polarity concerns during layout and simplifies protection of AC-coupled or differential signal lines.
What is the standoff voltage (VWM) of the 1.5SMC82CAHE3/57T?
The standoff voltage (VWM) of the 1.5SMC82CAHE3/57T is 70.1 V - the maximum DC or RMS voltage that can be continuously applied without exceeding 1.0 μA reverse leakage current. This provides a 10.1 V margin below the minimum breakdown voltage (77.9 V), ensuring stable operation during normal system bias.
Does the 1.5SMC82CAHE3/57T require a heatsink for standard operation?
No, the 1.5SMC82CAHE3/57T is designed for surface-mount operation on standard PCB copper pads (0.31" × 0.31") without external heatsinking. Its RθJA of 75 °C/W and RθJL of 15 °C/W allow full 1500 W surge dissipation during transient events, while steady-state power dissipation (PD = 6.5 W) is managed via PCB thermal spreading.
