Product details
Overview
1.5SMC100CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 100 V standoff voltage (VWM), and clamping voltage of 137 V at 10.9 A peak pulse current - deployed for lightning and inductive-switching surge protection on automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the 1.5SMC100CAHE3_A/H datasheet, 1.5SMC100CAHE3_A/H pinout, 1.5SMC100CAHE3_A/H application, or 1.5SMC100CAHE3_A/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, 137 V VC max under 10.9 A IPPM, and compatibility with automated SMT assembly on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown behavior in both polarities due to its bidirectional construction. It features glass-passivated junctions, meets MSL Level 1 per J-STD-020, and delivers 1500 W peak pulse power handling with 0.01% duty cycle repetition.
Thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads); it supports operating junction temperatures from –65 °C to +150 °C and is qualified to AEC-Q101 for automotive use. The 1.5SMC100CAHE3_A/H uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 100 V - maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown |
| VBR (Breakdown) | 105 V min / 116 V max at 1 mA - precise voltage threshold where avalanche conduction initiates in both directions |
| VC (Clamping) | 137 V at 10.9 A IPPM - peak voltage seen by protected circuit during worst-case 10/1000 μs surge |
| PPPM | 1500 W - surge energy absorption capability under standardized 10/1000 μs waveform with 0.01% duty cycle |
| ID (Leakage) | 1.0 μA max at 100 V - minimal reverse leakage ensures negligible standby power loss and signal integrity |
| TJ max | +150 °C - enables reliable operation in under-hood automotive and high-temperature industrial environments |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower PPPM (600 W), same VWM (100 V), SMB package (smaller footprint, higher RθJA) | Not suitable for high-energy surges exceeding 600 W; limited thermal dissipation in confined layouts | Select when board space is constrained and surge energy is ≤600 W (e.g., low-power consumer ports) |
| 1.5KE100CA | Through-hole DO-201 package, identical electrical specs but incompatible with SMT assembly | Requires wave soldering or hand-soldering; unsuitable for automated production or compact PCBs | Choose only for legacy through-hole designs or prototyping where rework flexibility outweighs volume manufacturing needs |
Compared with SMBJ100CA and 1.5KE100CA, the 1.5SMC100CAHE3_A/H uniquely balances 1500 W surge capacity, SMT compatibility, AEC-Q101 qualification, and DO-214AB thermal performance - making it optimal for automotive and industrial SMT production where reliability and energy handling are co-prioritized.

FAQ
What is the clamping voltage of the 1.5SMC100CAHE3_A/H under maximum surge conditions?
The 1.5SMC100CAHE3_A/H has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 10.9 A using the 10/1000 μs waveform. This value is measured at the device terminals under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The 1.5SMC100CAHE3_A/H maintains this clamping performance across its specified operating temperature range.
Is the 1.5SMC100CAHE3_A/H suitable for automotive applications?
Yes, the 1.5SMC100CAHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use with suffix "HE3" indicating RoHS-compliant and AEC-Q101–qualified construction. It meets stress test requirements for temperature cycling, high-temperature reverse bias, and mechanical shock - making it appropriate for engine control units, body electronics, and ADAS sensor interfaces where reliability under harsh conditions is critical. The 1.5SMC100CAHE3_A/H is listed in Vishay's automotive-grade product portfolio.
How does the bidirectional design of the 1.5SMC100CAHE3_A/H affect its circuit placement?
The 1.5SMC100CAHE3_A/H has no polarity marking and functions identically in both voltage polarities, allowing direct placement across any two nodes requiring symmetrical overvoltage protection - such as differential signal lines, AC power inputs, or ungrounded sensor outputs. Unlike unidirectional TVS diodes, it eliminates orientation errors during automated placement and simplifies layout by removing the need for cathode alignment checks. The 1.5SMC100CAHE3_A/H achieves matched breakdown and clamping in both directions per its datasheet specifications.
What is the thermal resistance profile of the 1.5SMC100CAHE3_A/H?
The 1.5SMC100CAHE3_A/H exhibits a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads resistance (RθJL) of 15 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per JEDEC standards. These values enable effective heat dissipation during repetitive surge events and support continuous operation at ambient temperatures up to +125 °C when derated per Fig. 2 in the datasheet. The 1.5SMC100CAHE3_A/H thermal performance is validated for SMC package mounting per Vishay's recommended pad layout.
Does the 1.5SMC100CAHE3_A/H require special handling or storage conditions?
No special handling beyond standard MSL Level 1 requirements is needed for the 1.5SMC100CAHE3_A/H. It is rated per J-STD-020 for unlimited floor life at ≤30 °C/60% RH and withstands peak reflow temperatures up to 260 °C without baking. The 1.5SMC100CAHE3_A/H uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, ensuring robust solderability in lead-free processes. Storage should follow Vishay's general guidelines for humidity-sensitive devices - dry packing is not required.
