Product details
Overview
1.5SMC100AHE3_A/I from Vishay General Semiconductor is a unidirectional 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), 10.9 A peak pulse current, and 137 V maximum clamping voltage at rated current. It operates across -65 °C to +150 °C and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the 1.5SMC100AHE3_A/I datasheet, 1.5SMC100AHE3_A/I pinout, 1.5SMC100AHE3_A/I application, or 1.5SMC100AHE3_A/I equivalent, key selection criteria include its 85.5 V standoff voltage, 95–105 V breakdown range at 1 mA, low 1.0 μA leakage at VWM, ±0.106 %/°C VBR temperature coefficient, and RoHS-compliant, halogen-free construction with matte tin-plated leads.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to deliver fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 μs transients at 0.01 % duty cycle. Its thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads), enabling reliable operation on standard 8.0 mm × 8.0 mm copper pads.
The device meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak, supports automated placement, and is UL 497B recognized (QVGQ2, E136766). Polarity is marked by a cathode band; no marking is used for bidirectional variants - but this part is unidirectional.

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-E3/52 | Lower peak power (600 W), SMB package (smaller footprint), same VWM/VC specs | Not suitable for IEC 61000-4-5 Level 4; limited to consumer-grade surge immunity | Select when board space is constrained and surge threat level is ≤ Level 2 |
| 1.5KE100A | Through-hole DO-201 package, identical electrical specs but no AEC-Q101 or MSL Level 1 rating | Lacks automotive qualification and lead-free reflow compatibility | Choose only for legacy through-hole designs where surface-mount is not feasible |

FAQ
What is the standoff voltage of the 1.5SMC100AHE3_A/I?
The 1.5SMC100AHE3_A/I has a maximum reverse standoff voltage (VWM) of 85.5 V. This means it remains non-conductive up to this DC or RMS voltage level, providing reliable isolation during normal operation while triggering clamping only when transients exceed its breakdown threshold of 95–105 V. This value is confirmed in the Vishay 88303 datasheet Table on page 2.
Is the 1.5SMC100AHE3_A/I AEC-Q101 qualified?
Yes, the 1.5SMC100AHE3_A/I is AEC-Q101 qualified, as indicated by the "HE3" suffix and explicitly stated in the Vishay 88303 datasheet revision 09-Mar-2026. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and accelerated life testing required for automotive electronic modules.
What package does the 1.5SMC100AHE3_A/I use?
The 1.5SMC100AHE3_A/I uses the SMC (DO-214AB) surface-mount package, measuring 7.11 mm × 6.22 mm × 2.62 mm with a cathode band marking. Its mechanical outline and pad layout recommendations are specified in the Vishay 88303 datasheet page 5, and it meets UL 94 V-0 flammability rating.
What is the clamping voltage of the 1.5SMC100AHE3_A/I at peak pulse current?
The 1.5SMC100AHE3_A/I has a maximum clamping voltage (VC) of 137 V at its rated peak pulse current (IPPM) of 10.9 A, measured under the standardized 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is guaranteed per the Vishay 88303 datasheet electrical characteristics table.
Does the 1.5SMC100AHE3_A/I have lead-free and RoHS-compliant construction?
Yes, the 1.5SMC100AHE3_A/I is RoHS-compliant and halogen-free, as confirmed by the "HE3" and "HM3" suffix nomenclature in Vishay's ordering information. Its matte tin-plated leads meet J-STD-002 solderability requirements, and it complies with JEDEC JESD201 Class 2 whisker resistance standards.
