Product details
Overview
1.5SMC100A-E3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 100 V breakdown voltage (VBR = 95–105 V at 1 mA), 85.5 V maximum stand-off voltage (VWM), 137 V clamping voltage (VC) at 10.9 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial motor drive control circuits.
For engineers reviewing the 1.5SMC100A-E3/9AT datasheet, 1.5SMC100A-E3/9AT pinout, 1.5SMC100A-E3/9AT application, or 1.5SMC100A-E3/9AT equivalent, key selection criteria include unidirectional polarity, SMC (DO-214AB) package compatibility, AEC-Q101 qualification eligibility (via HE3 suffix), thermal resistance (RθJA = 75 °C/W), and compliance with UL 497B surge protector classification.
Technical Context
This TVS diode operates as a clamping device that transitions from high-impedance standby to low-impedance conduction when reverse voltage exceeds VBR, limiting transient energy to protected downstream circuitry. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and fast response time (<1.0 ns), critical for suppressing ESD and lightning-induced surges.
The 1.5SMC100A-E3/9AT is rated for 1500 W peak pulse power under standardized 10/1000 µs waveform, with derating above 25 °C per Fig. 2 and validated operation across -65 °C to +150 °C junction temperature range. Its unidirectional configuration requires cathode-band orientation during PCB layout, and it meets J-STD-020 MSL Level 1 reflow profile (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95.0 V / 105 V at IT = 1 mA - defines precise voltage threshold for avalanche conduction onset |

Applications
| Automotive Sensor Interface | Industrial Motor Drive Control |
|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between signal line and chassis ground, absorbing >100 A surge currents. Use Value: Limits transient voltage to ≤137 V, preserving integrity of 5 V tolerant transceivers and preventing latch-up in microcontroller I/O. |
Use Scenario: Safeguarding gate driver inputs and feedback sensing nodes in 3-phase inverter modules exposed to switching noise and back-EMF spikes. IC Role / Device Role / Timing Role: Fast-response voltage clamp on isolated DC-link monitoring paths and optocoupler supply rails. Use Value: Clamps 10/1000 µs surges within 1 ns, maintaining signal fidelity for PWM timing accuracy and preventing false fault triggering. |
| Telecom Power Input Protection | Consumer Power Adapter Output Stage |
Use Scenario: Secondary-side overvoltage suppression on PoE-powered equipment (e.g., IP cameras, access points) subjected to induced lightning surges. IC Role / Device Role / Timing Role: Standoff-rated TVS on 48 V DC input, coordinated with upstream MOVs and fuses. Use Value: Withstands repetitive 1500 W pulses at 0.01% duty cycle, enabling reliable field operation without degradation. |
Use Scenario: Output rail protection in USB-C PD adapters and multi-port chargers against output short-circuit transients and hot-plug events. IC Role / Device Role / Timing Role: Final-stage clamp on regulated 5–20 V output, placed after DC-DC converter and before connector. Use Value: Low VWM/VBR ratio (85.5/95 V) ensures no conduction during normal regulation, eliminating standby power loss. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A-E3/52T | Lower PPPM (600 W), SMB package (smaller footprint, higher RθJA = 85 °C/W) | Suitable for space-constrained consumer electronics; insufficient for automotive load dump | Select when board area is limited and surge requirements are ≤IEC 61000-4-5 Level 2 |
| 1.5KE100A | Through-hole DO-201 package, identical electrical specs but incompatible with SMT assembly | Used in legacy industrial controls where manual assembly or repairability is prioritized | Choose only if through-hole mounting is mandated and reflow compatibility is not required |
Compared with SMBJ100A-E3/52T and 1.5KE100A, the 1.5SMC100A-E3/9AT delivers optimal balance of 1500 W surge capacity, SMT manufacturability, and thermal performance in compact SMC packaging - making it the preferred choice for new automotive and industrial designs requiring AEC-Q101 readiness and high-reliability surface mount integration.

FAQ
What is the clamping voltage of the 1.5SMC100A-E3/9AT under full-rated surge conditions?
The 1.5SMC100A-E3/9AT exhibits a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 10.9 A using the standard 10/1000 µs waveform. This value is measured per Figure 1 in the Vishay datasheet 88303 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Is the 1.5SMC100A-E3/9AT AEC-Q101 qualified?
The 1.5SMC100A-E3/9AT itself is RoHS-compliant and commercial-grade; however, the AEC-Q101 qualified variant uses the HE3 suffix (e.g., 1.5SMC100AHE3_A/I). The "E3" in 1.5SMC100A-E3/9AT denotes RoHS compliance only - qualification status must be verified via the specific HE3 or HM3 ordering code and associated test reports.
What is the maximum reverse leakage current for the 1.5SMC100A-E3/9AT at its stand-off voltage?
At its maximum stand-off voltage (VWM = 85.5 V), the 1.5SMC100A-E3/9AT guarantees a maximum reverse leakage current (ID) of 1.0 µA at TA = 25 °C. This low leakage ensures minimal power loss in always-on circuits and preserves battery life in automotive standby modes.
Can the 1.5SMC100A-E3/9AT be used in bidirectional applications?
No - the 1.5SMC100A-E3/9AT is strictly unidirectional, as indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay specifies the "CA" suffix (e.g., 1.5SMC100CA), which provides symmetrical clamping in both polarities and omits polarity marking on the package.
What is the thermal resistance and how does it affect PCB layout for the 1.5SMC100A-E3/9AT?
The 1.5SMC100A-E3/9AT 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 under repetitive surge conditions, PCB layout must adhere to this pad size and avoid excessive copper isolation - undersized pads increase thermal impedance and risk premature thermal failure.
