Product details
Overview
1.5SMC10A-E3/9AT 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 1500 W peak pulse power (10/1000 μs), 14.5 V clamping voltage at 103 A peak pulse current, and 8.55 V stand-off voltage - deployed across automotive sensor lines, industrial I/O ports, and telecom interface circuits.
For engineers reviewing the 1.5SMC10A-E3/9AT datasheet, 1.5SMC10A-E3/9AT pinout, 1.5SMC10A-E3/9AT application, or 1.5SMC10A-E3/9AT equivalent, key selection criteria include unidirectional polarity, 10.5 V breakdown voltage at 1 mA, 10 μA max reverse leakage at VWM, thermal resistance of 75 °C/W, and RoHS-compliant matte tin-plated leads meeting J-STD-002 solderability.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, responding to transient overvoltages within picoseconds by transitioning from high-impedance to low-impedance state. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance under repetitive 10/1000 μs surges at 0.01% duty cycle.
Rated for -65 °C to +150 °C operating junction temperature, it delivers 1500 W peak pulse power when mounted on 8.0 mm × 8.0 mm copper pads per terminal and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It is not AEC-Q101 qualified - the HE3/HM3 suffix denotes automotive qualification; E3 denotes commercial-grade RoHS compliance only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 1500 W - sustains single high-energy transients without failure, e.g., lightning-induced surges on 24 V industrial bus lines |
| Stand-off Voltage (VWM) | 8.55 V - maximum continuous reverse voltage before significant leakage; sets minimum system operating margin |
| Breakdown Voltage (VBR) | 9.50–10.5 V at 1 mA - precise conduction onset threshold enabling accurate overvoltage trip point design |
| Clamping Voltage (VC) | 14.5 V at 103 A IPPM - limits downstream voltage during surge, protecting 15 V-rated ICs and MOSFET gates |
| Reverse Leakage Current | 10 μA max at 8.55 V - negligible standby power loss and signal integrity impact in always-on sensor interfaces |
| Junction-to-Ambient RθJA | 75 °C/W - defines thermal derating curve; requires ≥8 mm² copper pad per lead for full 1500 W rating |
| Operating Temperature Range | -65 °C to +150 °C - supports deployment in under-hood automotive, outdoor telecom, and factory-floor industrial environments |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with matte tin-plated leads; cathode indicated by band on body; compliant with UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to ground or lower-potential rail | Provides low-forward-voltage path during surge clamping; must be routed to lowest-impedance ground plane |
| Cathode | Current exit point in forward bias; connected to protected line | Band-marked terminal; ties directly to signal/power line requiring transient suppression (e.g., CAN_H, RS-485 A) |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) without derating in standard PCB layouts |
| Glass-passivated junction | Ensures long-term stability of VBR and low leakage drift over 10+ years in harsh thermal cycling environments |
| MSL Level 1 moisture sensitivity | Allows direct placement into reflow ovens without baking; eliminates pre-conditioning delays in high-volume manufacturing |
| RoHS-compliant, matte tin plating | Guarantees reliable solder joint formation per J-STD-002 and whisker resistance per JESD 201 Class 2 |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns), critical for protecting sub-20 V logic-level interfaces |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Same VWM (8.55 V) and VC (14.5 V), but lower PPPM (600 W); SMB package (DO-214AA), smaller footprint and higher RθJA (110 °C/W) | Suitable for space-constrained consumer electronics where surge energy rarely exceeds 600 W | Select SMBJ10A only if layout area is limited and worst-case surge energy is confirmed ≤600 W per IEC 61000-4-5 |
| 1.5KE10A | Through-hole TO-204AE (DO-15) package; identical electrical specs but incompatible mounting; higher mechanical robustness and lower RθJA (50 °C/W) | Preferred for high-reliability military or legacy industrial designs requiring through-hole assembly and manual repair | Choose 1.5KE10A only when SMT is prohibited or thermal management demands >1500 W capability with heatsinking |
Compared with SMBJ10A and 1.5KE10A, the 1.5SMC10A-E3/9AT uniquely balances 1500 W surge handling, SMT manufacturability, and commercial-grade RoHS compliance in the widely adopted SMC footprint - making it optimal for volume automotive and industrial designs requiring validated surface-mount surge immunity.

FAQ
What is the clamping voltage of the 1.5SMC10A-E3/9AT under maximum rated surge current?
The 1.5SMC10A-E3/9AT has a maximum clamping voltage (VC) of 14.5 V at 103 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured under standardized test conditions with the device mounted on 8.0 mm × 8.0 mm copper pads per terminal, ensuring repeatable protection performance in production PCB layouts.
Is the 1.5SMC10A-E3/9AT AEC-Q101 qualified?
No, the 1.5SMC10A-E3/9AT is not AEC-Q101 qualified. The "E3" suffix indicates RoHS-compliant commercial grade only. For automotive-qualified versions, select part numbers with "HE3" or "HM3" suffixes (e.g., 1.5SMC10AHE3_A/I), which carry full AEC-Q101 certification and extended temperature validation.
What does the "/9AT" suffix mean in 1.5SMC10A-E3/9AT?
The "/9AT" suffix denotes packaging: 13-inch diameter plastic tape-and-reel format containing 3500 units. This differs from "/57T", which specifies a 7-inch reel with 850 units. Both use the same carrier tape specifications per EIA-481, ensuring compatibility with standard SMT pick-and-place equipment.
Can the 1.5SMC10A-E3/9AT be used in bidirectional protection circuits?
No, the 1.5SMC10A-E3/9AT is unidirectional only. Bidirectional variants use the "CA" suffix (e.g., 1.5SMC10CA). Using a unidirectional device like the 1.5SMC10A-E3/9AT in bidirectional applications risks forward conduction during negative transients, potentially damaging downstream circuitry or failing to clamp correctly.
What is the thermal resistance of the 1.5SMC10A-E3/9AT, and how does it affect layout?
The 1.5SMC10A-E3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 8.0 mm × 8.0 mm copper pads per terminal. To achieve full 1500 W pulse rating, PCB layout must allocate ≥64 mm² of 2-oz copper per pad; reduced copper area increases junction temperature and requires derating per Figure 2 in the datasheet.
