Product details
Overview
1.5SMC8.2CA-E3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 8.2 V breakdown voltage (VBR min/max = 7.79 V / 8.61 V at 10 mA), 7.02 V stand-off voltage (VWM), clamps to ≤12.1 V at 200 A peak pulse current (10/1000 µs), and delivers 1500 W peak pulse power capability - ideal for protecting automotive sensor signal lines against ESD and lightning-induced transients.
For engineers reviewing the 1.5SMC8.2CA-E3/57T datasheet, 1.5SMC8.2CA-E3/57T pinout, 1.5SMC8.2CA-E3/57T application, or 1.5SMC8.2CA-E3/57T equivalent, key selection criteria include bidirectional clamping symmetry, low clamping voltage under high surge current, RoHS-compliant commercial-grade construction with matte tin leads, and compatibility with automated SMT placement on standard PCB pad layouts per JEDEC DO-214AB footprint.
Technical Context
The 1.5SMC8.2CA-E3/57T operates as a bidirectional avalanche diode, symmetrically clamping voltage transients in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, enabling fast response (<1 ns) to transient events such as ESD (IEC 61000-4-2) and inductive switching spikes.
Thermally, it exhibits RθJA = 75 °C/W (typ.) and RθJL = 15 °C/W (typ.), supporting reliable operation up to TJ = 150 °C. It meets MSL Level 1 per J-STD-020 and is rated for repetitive 10/1000 µs surges at 0.01% duty cycle, with derating above 25 °C ambient per Fig. 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V at IT = 10 mA - defines precise avalanche onset threshold for bidirectional clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA | Lower PPPM (600 W), smaller SMB package (DO-214AA), VC = 12.8 V @ 49.2 A | Limited to lower-energy transients; less suitable for automotive load dump or industrial 200 A surges | Select when board space is constrained and surge energy is <600 W; verify thermal margin with reduced pad area |
| 1.5KE8.2CA | Through-hole TO-204AE (DO-15), same VBR/VC, PPPM = 1500 W, but no MSL rating or SMT compatibility | Requires wave soldering or hand assembly; incompatible with automated SMT lines and high-density layouts | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ8.0CA and 1.5KE8.2CA, the 1.5SMC8.2CA-E3/57T uniquely combines 1500 W surge handling, SMC's superior thermal performance (RθJL = 15 °C/W), and full MSL Level 1 compliance - making it the optimal choice for high-reliability, high-volume SMT applications demanding automotive or industrial robustness.

FAQ
What does the "CA" suffix indicate in 1.5SMC8.2CA-E3/57T?
The "CA" suffix in 1.5SMC8.2CA-E3/57T denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., 1.5SMC8.2A), the 1.5SMC8.2CA-E3/57T has no cathode band marking and functions identically regardless of voltage polarity - essential for protecting AC-coupled or differential signal paths such as CAN bus or telecom lines.
Is 1.5SMC8.2CA-E3/57T RoHS-compliant and lead-free assembly compatible?
Yes, the 1.5SMC8.2CA-E3/57T carries the "E3" suffix, indicating full RoHS compliance and qualification for lead-free reflow soldering with a maximum peak temperature of 260 °C. It meets J-STD-020 MSL Level 1 and passes JESD 201 Class 2 whisker testing, making it suitable for high-yield, environmentally compliant SMT manufacturing without moisture sensitivity concerns.
What is the maximum clamping voltage of 1.5SMC8.2CA-E3/57T under surge conditions?
The 1.5SMC8.2CA-E3/57T clamps to a maximum of 12.1 V when subjected to its rated 200 A peak pulse current (10/1000 µs waveform). This value is measured per standard test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads) and represents the upper limit of voltage seen by protected circuitry during worst-case transient events.
Can 1.5SMC8.2CA-E3/57T be used in automotive applications?
While the base 1.5SMC8.2CA-E3/57T is commercial-grade, Vishay offers AEC-Q101-qualified versions (e.g., 1.5SMC8.2CAHE3_A) with identical electrical specs and enhanced reliability testing. The 1.5SMC8.2CA-E3/57T itself is widely deployed in non-safety-critical automotive subsystems - including body control modules and infotainment interfaces - where its 1500 W surge rating and -65 °C to +150 °C operating range meet system-level requirements.
How does the SMC (DO-214AB) package of 1.5SMC8.2CA-E3/57T compare thermally to SMB (DO-214AA)?
The SMC package used in 1.5SMC8.2CA-E3/57T provides significantly better thermal performance than SMB: typical junction-to-lead thermal resistance is 15 °C/W versus ~25–30 °C/W for SMB, and junction-to-ambient is 75 °C/W (with recommended 8 mm × 8 mm pads) versus ~100–120 °C/W for SMB. This enables higher sustained power dissipation and improved reliability under repetitive surge conditions.
