Product details
Overview
1.5SMC100CAH from Taiwan Semiconductor is a bidirectional 1500W surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, with 95V–105V breakdown voltage (VBR), 85.5V working stand-off voltage (VWM), 11.4A peak pulse current (IPPM), and 137V clamping voltage (VC @ IPPM). It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the 1.5SMC100CAH datasheet, 1.5SMC100CAH pinout, 1.5SMC100CAH application, or 1.5SMC100CAH equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, sub-1ps response time, <1µA leakage at VWM, and thermal resistance (RθJA = 50°C/W) for high-reliability board-level surge immunity.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, enabling single-device protection of AC-coupled or floating signal/power lines without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low temperature coefficient (0.106%/°C), critical for consistent clamping across automotive temperature ranges (−55°C to +150°C).
The device meets ISO 7637-2 test pulses via fast response (<1.0ps) and robust 1500W peak pulse power handling at 10/1000µs waveform. Its DO-214AB package delivers RθJC = 15°C/W for effective heat transfer to PCB copper, supporting sustained operation under repetitive surge conditions in engine control units and battery management systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | 600W rating, DO-214AA (SMB) package, higher RθJA (65°C/W), same VBR range | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a in automotive | Select when space-constrained layouts require smaller footprint and surge energy ≤600W |
| 1.5KE100CA | Through-hole TO-204AE (DO-15), 1500W, but slower response (>1ps), no AEC-Q101 qualification | Not suitable for automated SMT lines or automotive qualification programs | Select only for legacy through-hole designs where reflow compatibility and AEC-Q101 are not required |
Compared with SMBJ100CA and 1.5KE100CA, the 1.5SMC100CAH uniquely combines AEC-Q101 qualification, 1500W SMT packaging, and sub-1ps response-making it the only choice for new automotive electronics requiring ISO 7637-2 compliance and high-volume placement.

FAQ
What is the clamping voltage of the 1.5SMC100CAH under a 10/1000µs surge?
The 1.5SMC100CAH has a maximum clamping voltage (VC) of 137V when subjected to its rated peak pulse current of 11.4A (10/1000µs waveform). This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during surge events. The 1.5SMC100CAH maintains this clamping performance across its full operating temperature range (−55°C to +150°C) with minimal drift due to its 0.106%/°C VBR temperature coefficient.
Is the 1.5SMC100CAH suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the 1.5SMC100CAH is explicitly AEC-Q101 qualified per the manufacturer's datasheet (Version B2207). It undergoes stress testing for high-temperature operating life, temperature cycling, and mechanical shock-ensuring reliability in under-hood and chassis-mounted automotive systems. The 1.5SMC100CAH also meets ISO 7637-2 Pulse 1/2a/2b/3a/3b requirements, making it appropriate for engine control units, body control modules, and ADAS power domains where the 1.5SMC100CAH serves as primary surge protection.
How does the bidirectional configuration of the 1.5SMC100CAH affect PCB layout?
The 1.5SMC100CAH is a symmetrical bidirectional TVS, meaning either terminal functions identically regardless of voltage polarity-eliminating orientation constraints during placement. Unlike unidirectional variants (e.g., 1.5SMC100CH), the 1.5SMC100CAH has no cathode band marking and requires no polarity-aware routing. This simplifies layout for AC-coupled interfaces, floating grounds, or differential bus protection, reducing assembly errors and enabling compact two-terminal placement directly across power rails or signal pairs without concern for anode/cathode assignment.
What is the maximum steady-state power dissipation for the 1.5SMC100CAH at 25°C ambient?
The 1.5SMC100CAH has a steady-state power dissipation (PD) rating of 6.5W at TA = 25°C, as specified in its Absolute Maximum Ratings table. This value reflects continuous DC or low-frequency power handling-not transient surge capability-and assumes adequate PCB copper area for thermal conduction. In practice, the 1.5SMC100CAH is used for transient suppression only; sustained power dissipation should remain well below 6.5W to avoid junction temperature exceeding +150°C, especially in enclosed or high-ambient environments where derating per Fig.2 applies.
Does the 1.5SMC100CAH have moisture sensitivity level (MSL) restrictions for reflow soldering?
No, the 1.5SMC100CAH carries Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it has unlimited floor life and requires no baking or dry-pack handling prior to reflow soldering. This allows direct use from tape-and-reel packaging in standard SMT lines without preconditioning delays. The 1.5SMC100CAH's DO-214AB molding compound and matte tin plating ensure robust solder joint formation under IPC-J-STD-002-compliant reflow profiles, supporting high-yield automated assembly for automotive and industrial production volumes.
