Product details
Overview
1.5SMC8.2A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 7.79 V to 8.61 V breakdown voltage (VBR) at 10 mA, 7.02 V stand-off voltage (VWM), 124 V maximum clamping voltage (VC) at 200 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the 1.5SMC8.2A-M3/57T datasheet, 1.5SMC8.2A-M3/57T pinout, 1.5SMC8.2A-M3/57T application, or 1.5SMC8.2A-M3/57T equivalent, this page delivers verified electrical parameters, thermal derating behavior, polarity marking convention, halogen-free RoHS-compliant construction, and AEC-Q101 qualification status for automotive-grade deployment.
Technical Context
The 1.5SMC8.2A-M3/57T operates as a unidirectional avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to limit transient overvoltage before damage occurs. Its clamping action begins at VWM = 7.02 V and fully engages at VBR = 7.79–8.61 V, sustaining up to 200 A IPPM under standardized 10/1000 µs surge conditions.
Thermally, it exhibits RθJA = 75 °C/W (junction-to-ambient, mounted on 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W (junction-to-leads), enabling reliable operation up to TJ = +150 °C. The cathode band denotes polarity, and its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | Lower PPPM (600 W), same VWM (6.4 V), smaller SMB package (DO-214AA) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 | Select only when board space is constrained and surge threat level is ≤ Level 2 |
| 1.5KE8.2A | Through-hole TO-204AE (DO-41) package, identical VBR/VC, same PPPM | Not suitable for automated SMT assembly; incompatible with high-density PCB layouts | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required |

The 1.5SMC8.2A-M3/57T has a specified breakdown voltage (VBR) range of 7.79 V to 8.61 V at 10 mA test current, representing ±5.5 % tolerance about the nominal 8.2 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports reliable design margining in safety-critical circuits.
Is the 1.5SMC8.2A-M3/57T suitable for automotive applications?
Yes, the 1.5SMC8.2A-M3/57T is AEC-Q101 qualified and carries the HM3 suffix designation indicating halogen-free, RoHS-compliant, and automotive-grade construction. It meets stringent requirements for under-hood and chassis-mounted electronics, including operation from –65 °C to +150 °C and resistance to mechanical shock and thermal cycling.
What does the "M3" suffix mean in 1.5SMC8.2A-M3/57T?
The "M3" suffix in 1.5SMC8.2A-M3/57T indicates halogen-free, RoHS-compliant construction with matte tin-plated leads that satisfy JESD 201 Class 2 whisker resistance. It distinguishes this variant from the "E3" (RoHS-compliant commercial grade) and "HM3" (AEC-Q101 qualified + halogen-free) versions - confirming environmental compliance without automotive qualification.
How is polarity marked on the 1.5SMC8.2A-M3/57T?
The 1.5SMC8.2A-M3/57T uses a cathode band printed on the body to indicate the cathode terminal - the banded end connects to the higher-potential side of the protected circuit. This marking is visible under standard optical inspection and aligns with IPC-A-610 acceptance criteria for SMT polarity verification during assembly.
What is the maximum clamping voltage of the 1.5SMC8.2A-M3/57T at rated surge current?
The 1.5SMC8.2A-M3/57T exhibits a maximum clamping voltage (VC) of 124 V when subjected to its rated 200 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream IC voltage stress analysis.
