Product details
Overview
1.5SMC100CA-E3/9AT from Vishay General Semiconductor is a bidirectional 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), 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 sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the 1.5SMC100CA-E3/9AT datasheet, 1.5SMC100CA-E3/9AT pinout, 1.5SMC100CA-E3/9AT application, or 1.5SMC100CA-E3/9AT equivalent, this device delivers verified bidirectional clamping performance, AEC-Q101-qualified reliability (via HE3/HM3 variants), RoHS-compliant SMC (DO-214AB) packaging, and low incremental surge resistance for fast transient suppression in high-reliability DC power rails and bidirectional data lines.
Technical Context
This TVS operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM), while the 10/1000 μs waveform rating reflects real-world lightning and inductive-switching surge immunity per IEC 61000-4-5 Level 3–4 requirements.
The device exhibits a typical thermal resistance of 75 °C/W (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads, supporting sustained operation up to +150 °C junction temperature. Its 0.106 %/°C temperature coefficient of VBR ensures predictable voltage drift across automotive and industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 85.5 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown) | 95.0–105 V at 1.0 mA - Verified breakdown threshold range; ensures consistent turn-on during transients. |
| VC (Clamping) | 137 V at IPPM = 10.9 A - Peak voltage seen by protected circuit during 1500 W surge; directly limits stress on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling with 10/1000 μs waveform; meets IEC 61000-4-5 surge immunity requirements. |
| ID (Leakage) | <1.0 μA at VWM - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss. |
| TJ max. | +150 °C - Enables use in under-hood automotive, motor drives, and industrial enclosures without derating. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 3.2 mm min. creepage/clearance; compatible with automated reflow assembly. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability standards. Polarity: unmarked for bidirectional operation - symmetrical terminal configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional conduction path | No polarity marking required; either terminal serves as input/output for transient energy diversion in both directions. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Enables single-device protection against severe lightning-induced surges per IEC 61000-4-5, eliminating need for cascaded protection stages. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during clamping - critical for safeguarding 100 V-rated MOSFETs and gate drivers. |
| MSL Level 1 (260 °C peak reflow) | Supports lead-free reflow soldering without moisture sensitivity concerns - eliminates pre-bake requirement in high-volume SMT lines. |
| AEC-Q101 qualification (HE3/HM3 variants) | Validates reliability for automotive applications including engine control units, ADAS sensor hubs, and body electronics. |
| Glass passivated junction | Ensures stable VBR over lifetime and temperature; reduces parameter drift vs. epoxy-passivated alternatives. |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower PPPM (600 W), same VWM/VC ratings, SMB package (smaller footprint, higher RθJA). | Limited to lower-energy surges; unsuitable for IEC 61000-4-5 Level 4 compliance. | Select when board space is constrained and surge threat level is ≤600 W (e.g., consumer USB ports). |
| 1.5KE100CA | Through-hole DO-15 package, identical electrical specs but incompatible with SMT assembly. | Requires manual or wave-solder process; not viable for automated production or compact PCBs. | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMBJ100CA and 1.5KE100CA, the 1.5SMC100CA-E3/9AT uniquely balances 1500 W surge capacity, SMC surface-mount compatibility, and AEC-Q101-ready variants - making it the optimal choice for volume-manufactured automotive and industrial systems requiring validated high-energy clamping in automated assembly.

FAQ
What does the "CA" suffix indicate in 1.5SMC100CA-E3/9AT?
The "CA" suffix denotes a bidirectional configuration - meaning the 1.5SMC100CA-E3/9AT provides symmetrical clamping in both polarities, with no cathode/anode distinction. This enables direct placement across AC-coupled lines, differential buses, or ungrounded power rails without orientation concerns, unlike unidirectional "A" variants which require correct polarity alignment.
Is 1.5SMC100CA-E3/9AT RoHS-compliant and halogen-free?
Yes, the "E3" suffix in 1.5SMC100CA-E3/9AT confirms RoHS-compliance per EU Directive 2011/65/EU. It is not halogen-free; for halogen-free and RoHS-compliant versions, specify the "M3" suffix (e.g., 1.5SMC100CA-M3/9AT). Both meet JESD201 Class 2 whisker resistance and J-STD-002 solderability standards.
What is the maximum clamping voltage of 1.5SMC100CA-E3/9AT under surge conditions?
The 1.5SMC100CA-E3/9AT 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 represents the highest voltage imposed on the protected circuit during worst-case surge events and is critical for verifying compatibility with downstream component voltage ratings.
Can 1.5SMC100CA-E3/9AT be used in automotive applications?
Yes - while the base 1.5SMC100CA-E3/9AT is commercial-grade, Vishay offers AEC-Q101-qualified variants (e.g., 1.5SMC100CAHE3_A) with identical electrical specs and enhanced reliability testing. These qualified versions are approved for automotive powertrain, chassis, and ADAS subsystems where failure modes must meet stringent automotive quality standards.
What is the thermal resistance of 1.5SMC100CA-E3/9AT, and how does it affect layout?
The 1.5SMC100CA-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 TJ ≤ 150 °C under sustained 6.5 W dissipation, PCB layout must provide adequate copper area and avoid thermal bottlenecks - undersized pads or narrow traces will elevate junction temperature and reduce surge endurance.
