Product details
Overview
1.5SMC100AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 100 V standoff voltage (VWM), 105 V minimum breakdown voltage (VBR), 137 V maximum clamping voltage (VC) at 10.9 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive ECUs, industrial I/O modules, and telecom power supplies.
For engineers reviewing the 1.5SMC100AHE3/57T datasheet, 1.5SMC100AHE3/57T pinout, 1.5SMC100AHE3/57T application, or 1.5SMC100AHE3/57T equivalent, key selection criteria include clamping performance under 10/1000 μs transients, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients. Its unidirectional polarity (cathode-banded) ensures defined forward conduction path during overvoltage events.
The device operates across -65 °C to +150 °C junction temperature range and is rated for 200 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine). It meets MSL Level 1 per J-STD-020 and is RoHS-compliant with matte tin-plated leads solderable per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 85.5 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working margin. |
| VBR (Breakdown Voltage) | 95.0–105 V at 1 mA - Voltage at which device enters avalanche conduction; tight tolerance ensures predictable turn-on. |
| VC (Clamping Voltage) | 137 V at IPPM = 10.9 A - Peak voltage seen by protected circuit during 10/1000 μs transient; critical for IC/MOSFET survivability. |
| PPPM (Peak Pulse Power) | 1500 W - Maximum transient energy absorption capability under standardized 10/1000 μs waveform; enables high-energy surge handling. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on recommended 8.0 mm × 8.0 mm copper pads; determines derating above 25 °C ambient. |
| TJ max. | +150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive and industrial environments. |
| ID (Leakage Current) | 1.0 μA at VWM - Ultra-low reverse leakage preserves system efficiency and prevents false triggering in high-impedance circuits. |
Pinout & Package
Package: SMC (DO-214AB) - surface-mount, low-profile plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias | Connected to lower-potential side of protected line; defines directionality for unidirectional clamping. |
| Cathode (banded end) | Current exit terminal in forward bias; avalanche conduction node in reverse | Marked band identifies cathode; must be connected toward higher-potential rail to enable reverse-biased clamping action. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, ADAS, and body electronics. |
| 1500 W peak pulse power | Withstands high-energy transients per ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 without degradation. |
| Glass-passivated junction | Ensures stable avalanche characteristics, low leakage, and long-term parameter stability under thermal stress. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and reflow at peak 260 °C - compatible with standard lead-free SMT assembly processes. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during transient events, reducing stress on downstream MOSFETs and interface ICs. |
Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A | Same VWM (85.5 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 110 °C/W). | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); unsuitable for ISO 7637-2 load dump. | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin with layout. |
| 1.5KE100A | Same electrical specs, but axial-leaded DO-15 package; no AEC-Q101 qualification; higher mounting inductance. | Not suitable for automated SMT production or automotive vibration environments; requires manual assembly. | Choose only for prototyping or legacy through-hole designs where rework flexibility outweighs reliability requirements. |
Compared with SMAJ100A and 1.5KE100A, the 1.5SMC100AHE3/57T delivers superior surge robustness (1500 W vs. 400 W or axial-limited energy handling), AEC-Q101 compliance for automotive use, and optimized SMT thermal performance - making it the preferred choice for volume production in harsh-environment applications.

FAQ
What is the clamping voltage of the 1.5SMC100AHE3/57T under a 10/1000 μs transient?
The 1.5SMC100AHE3/57T has a maximum clamping voltage (VC) of 137 V at 10.9 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value is guaranteed per Vishay's datasheet (Document Number: 88303, Rev. 09-Mar-2026) and reflects worst-case performance under standardized surge conditions - critical for verifying safe operating margins of downstream ICs.
Is the 1.5SMC100AHE3/57T AEC-Q101 qualified?
Yes, the 1.5SMC100AHE3/57T is AEC-Q101 qualified. The "HE3" suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified construction, validated for automotive applications including temperature cycling, highly accelerated life testing (HALT), and ESD robustness. This qualification is confirmed in the Vishay 1.5SMC Series datasheet, Section "Mechanical Data" and Ordering Information table.
What is the standoff voltage (VWM) and why does it matter for the 1.5SMC100AHE3/57T?
The 1.5SMC100AHE3/57T has a standoff voltage (VWM) of 85.5 V - the maximum continuous reverse voltage it can block without significant leakage. This parameter ensures reliable operation under normal system conditions while maintaining sufficient margin below the 100 V nominal rating. Exceeding VWM risks premature conduction and power loss; staying within VWM guarantees <1.0 μA leakage at 25 °C, preserving signal integrity and efficiency.
Can the 1.5SMC100AHE3/57T be used in bidirectional configurations?
No, the 1.5SMC100AHE3/57T is unidirectional only, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., 1.5SMC100CA). Using the 1.5SMC100AHE3/57T in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit - always match polarity to application requirements.
What is the thermal resistance and how does it affect PCB layout for the 1.5SMC100AHE3/57T?
The 1.5SMC100AHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes optimal pad layout per Vishay's recommended footprint. Reducing copper area increases RθJA, raising junction temperature under sustained power dissipation - so PCB layout must replicate the specified pad dimensions to maintain thermal safety margins up to +150 °C TJ max.
