Product details
Overview
1.5SMC510A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, rated for 510 V breakdown voltage (VBR = 485–535 V at IT = 1.0 mA), 698 V maximum clamping voltage (VC) at 2.15 A peak pulse current (IPPM), and 1500 W peak pulse power (10/1000 μs). It protects power rails and signal lines in industrial motor drives against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5SMC510A-E3/57T datasheet, 1.5SMC510A-E3/57T pinout, 1.5SMC510A-E3/57T application, or 1.5SMC510A-E3/57T equivalent, this page delivers verified electrical parameters, thermal derating behavior, junction-to-ambient thermal resistance (RθJA = 75 °C/W), RoHS-compliant commercial-grade construction, and AEC-Q101 qualification path via HE3/HM3 variants.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated silicon junction technology for fast response (<1 ns) and low incremental surge resistance. Its 1500 W peak pulse rating is defined under standardized 10/1000 μs waveform conditions with 0.01% duty cycle.
Thermal performance is characterized by RθJA = 75 °C/W (typ.) on 8.0 mm × 8.0 mm copper pads and RθJL = 15 °C/W (typ.), enabling reliable operation up to TJ = +150 °C. The device meets J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 485 V / 535 V at IT = 1.0 mA - defines precise breakdown threshold for overvoltage triggering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ510A-E3/52 | Lower PPPM (600 W), SMB package (smaller footprint, higher RθJA = 90 °C/W), same VBR range | Suitable for space-constrained, lower-energy surge environments (e.g., sensor interfaces), not for 1500 W industrial transients | Select when board area is critical and surge threat level is limited to IEC 61000-4-5 Level 2 (1 kV) |
| 1.5KE510A | Through-hole DO-201 package, identical VBR/VC/PPPM, but slower thermal recovery and no MSL-1 rating | Used in legacy designs or prototyping where manual assembly or high-reliability through-hole mounting is required | Choose only if SMT assembly is unavailable or if mechanical robustness under vibration outweighs thermal and footprint advantages |
Compared with SMBJ510A-E3/52 and 1.5KE510A, the 1.5SMC510A-E3/57T delivers optimal balance of high-power surge handling (1500 W), surface-mount compatibility, and thermal performance (RθJA = 75 °C/W) in a widely adopted industrial package-making it the preferred choice for new designs targeting IEC 61000-4-5 Level 4 compliance.

FAQ
What is the maximum clamping voltage of the 1.5SMC510A-E3/57T under rated surge conditions?
The 1.5SMC510A-E3/57T exhibits a maximum clamping voltage (VC) of 698 V when subjected to its rated peak pulse current of 2.15 A (10/1000 μs waveform). This value is measured per Figure 1 in Vishay document 88303 and defines the upper voltage limit imposed on protected circuitry during transient events.
Is the 1.5SMC510A-E3/57T suitable for automotive applications?
The 1.5SMC510A-E3/57T itself is a commercial-grade RoHS-compliant part (E3 suffix); however, the 1.5SMC510AHE3_A variant is AEC-Q101 qualified and approved for automotive use. For body control modules or powertrain peripherals requiring automotive qualification, specify the HE3 suffix version-not the E3/57T.
What is the thermal resistance and how does it affect PCB layout for the 1.5SMC510A-E3/57T?
The 1.5SMC510A-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. To maintain safe junction temperatures during repetitive surges, PCB layout must replicate this minimum pad area and avoid excessive trace narrowing near the device terminals.
Does the 1.5SMC510A-E3/57T have bidirectional capability?
No-the 1.5SMC510A-E3/57T is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional versions use the "CA" suffix (e.g., 1.5SMC510CA). Using the 1.5SMC510A-E3/57T in bidirectional applications would result in forward conduction during negative transients and potential failure.
What is the reverse leakage current specification for the 1.5SMC510A-E3/57T at its stand-off voltage?
At its maximum reverse stand-off voltage (VWM = 434 V), the 1.5SMC510A-E3/57T guarantees a maximum reverse leakage current (ID) of 1.0 μA at TA = 25 °C. This low leakage ensures minimal power loss and signal integrity impact in high-impedance protection configurations.
