Product details
Overview
1.5SMC100A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 100 V standoff voltage (VWM), 105 V minimum breakdown voltage (VBR), and 137 V maximum clamping voltage (VC) at 10.9 A peak pulse current. It delivers 1500 W peak pulse power (10/1000 µs waveform) and operates across -65 °C to +150 °C junction temperature range, commonly deployed in automotive power line and industrial sensor interface protection.
For engineers reviewing the 1.5SMC100A-E3/57T datasheet, 1.5SMC100A-E3/57T pinout, 1.5SMC100A-E3/57T application, or 1.5SMC100A-E3/57T equivalent, key selection considerations include its unidirectional polarity, 85.5 V VWM, 137 V clamping performance under 10.9 A surge, RoHS-compliant matte tin terminations, and AEC-Q101 qualification readiness via HE3 suffix variants.
Technical Context
This TVS diode employs an avalanche breakdown mechanism to clamp transient overvoltages above its rated standoff voltage, responding in sub-nanosecond time to protect downstream circuitry. Its glass-passivated silicon junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, critical for consistent clamping during repetitive surges.
The device is rated for 1500 W peak pulse power per 10/1000 µs waveform at 0.01% duty cycle, with thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads). It supports unidirectional operation only, with cathode indicated by a band, and meets J-STD-020 MSL Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 85.5 V - Maximum continuous reverse operating voltage before clamping begins; sets upper limit for normal circuit operation. |
| VBR (min/max) | 95.0 V / 105 V at 1.0 mA test current - Confirmed avalanche onset range; ensures predictable turn-on behavior under transients. |
| VC @ IPPM | 137 V at 10.9 A - Clamped voltage during full-rated 1500 W surge; defines worst-case stress on protected IC or MOSFET. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected circuit's positive rail or signal line; conducts surge current to ground when voltage exceeds VBR. |
| Anode (unmarked end) | Reference/return path | Typically tied to system ground or low-side reference; completes conduction path during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 µs) | Enables protection against severe transients such as ISO 7637-2 Pulse 5a (load dump) in 12 V automotive systems. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on downstream components like microcontrollers or CAN transceivers during clamping. |
| Glass passivated junction | Ensures long-term stability of breakdown voltage and leakage current under thermal cycling and humidity exposure. |
| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning risk. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Same VWM (85.5 V), lower PPPM (600 W), SMB package (smaller footprint, higher RθJA = 90 °C/W) | Limited to lower-energy transients; unsuitable for automotive load dump or industrial lightning tests. | Select when board space is constrained and surge energy does not exceed 600 W. |
| 1.5KE100A | Same electrical specs but axial-leaded DO-201AD package; higher mounting thermal resistance and manual assembly requirement. | Not suitable for automated SMT production; requires through-hole layout and wave soldering. | Choose only for prototyping or legacy through-hole designs where rework flexibility outweighs production efficiency. |
Compared with SMBJ100A and 1.5KE100A, the 1.5SMC100A-E3/57T offers optimal balance of high-energy surge handling (1500 W), SMT compatibility, and thermal performance (RθJL = 15 °C/W), making it preferred for volume automotive and industrial power electronics where reliability and manufacturability are co-prioritized.

FAQ
What is the maximum clamping voltage of the 1.5SMC100A-E3/57T under full-rated surge conditions?
The 1.5SMC100A-E3/57T exhibits a maximum clamping voltage (VC) of 137 V when subjected to its rated 10.9 A peak pulse current (IPPM) using 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 worst-case transient events.
Is the 1.5SMC100A-E3/57T suitable for automotive applications requiring AEC-Q101 qualification?
The 1.5SMC100A-E3/57T itself carries the commercial-grade E3 suffix and is not AEC-Q101 qualified. However, Vishay offers the functionally identical 1.5SMC100AHE3_A variant (with HE3 suffix), which is AEC-Q101 qualified and shares the same electrical characteristics and SMC package. For automotive use, specify the HE3 version.
What is the standoff voltage (VWM) of the 1.5SMC100A-E3/57T, and how does it relate to system operating voltage?
The 1.5SMC100A-E3/57T has a standoff voltage (VWM) of 85.5 V, meaning it remains non-conductive up to this reverse voltage. To ensure reliable operation, the system's maximum continuous DC or peak AC voltage must remain below 85.5 V-commonly applied in 72 V nominal industrial buses or 12 V/24 V automotive systems with margin for ripple and transients.
Does the 1.5SMC100A-E3/57T have bidirectional capability?
No, the 1.5SMC100A-E3/57T is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional versions use the "CA" suffix (e.g., 1.5SMC100CA). Using this part in bidirectional signal paths would require external circuitry or selection of the CA variant to avoid forward conduction during negative transients.
What is the thermal resistance and power derating behavior of the 1.5SMC100A-E3/57T?
The 1.5SMC100A-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads resistance (RθJL) of 15 °C/W. Its peak pulse power must be derated linearly above 25 °C ambient per Figure 2 in document 88303-e.g., at 85 °C TA, PPPM drops to ~850 W, requiring layout review for copper pad area and airflow if sustained high-temp operation is expected.
