Product details
Overview
1.5SMC16CA-M3/9AT from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on signal and power lines. It features a 13.6 V stand-off voltage (VWM), 15.2–16.8 V breakdown voltage (VBR) at 1 mA, 22.5 V maximum clamping voltage (VC) at 66.7 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, sensor interfaces, and automotive ECUs against ESD and lightning-induced surges.
For engineers reviewing the 1.5SMC16CA-M3/9AT datasheet, 1.5SMC16CA-M3/9AT pinout, 1.5SMC16CA-M3/9AT application, or 1.5SMC16CA-M3/9AT equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.45), halogen-free RoHS-compliant construction (M3 suffix), and compatibility with automated SMT placement on industrial and automotive PCBs.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both directions, enabling robust surge suppression without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the SMC package supports high thermal dissipation via copper pad mounting per JESD22-B102.
The 1.5SMC16CA-M3/9AT is rated for repetitive 10/1000 µs pulses at 0.01% duty cycle and derates linearly above 25 °C ambient, with RθJA = 75 °C/W and TJ(max) = +150 °C. It meets MSL Level 1 per J-STD-020 and is halogen-free per IEC 61249-2-21.

Applications
| Automotive Sensor Interface Protection | Industrial CAN Bus Line Protection |
|---|---|
Use Scenario: Protecting analog sensor outputs (e.g., pressure, temperature) in engine control modules from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential sensor pair or supply rail to limit transient excursions.

IC Role / Device Role / Timing Role: Bidirectional TVS placed across D+/D− and VBUS/GND to suppress differential and common-mode transients. Use Value: Sub-1 ns response ensures clamping occurs before USB PHY damage threshold is exceeded, validated per IEC 61000-4-2 Level 4. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | Lower PPPM (600 W), same VWM/VC, SMB package (smaller footprint, higher RθJA) | Best suited for space-constrained consumer electronics with lower surge exposure (IEC 61000-4-5 Level 2) | Select when board area is critical and surge threat level is moderate; verify thermal margin with reduced copper pad area. |
| 1.5KE16CA | Through-hole TO-204AA (DO-41), same electrical specs but higher RθJA (100 °C/W), not SMT-compatible | Used in legacy industrial controls where manual assembly or high-reliability through-hole mounting is required | Choose only if SMT is unavailable; requires PCB redesign and eliminates automated placement benefit of 1.5SMC16CA-M3/9AT. |
Compared with SMBJ16CA and 1.5KE16CA, the 1.5SMC16CA-M3/9AT delivers 2.5× higher surge power in an SMT-optimized package with superior thermal performance (RθJA = 75 °C/W vs. 100–120 °C/W), making it preferred for automotive and industrial designs requiring AEC-Q101-aligned reliability and high-volume manufacturing.

FAQ
What is the clamping voltage of the 1.5SMC16CA-M3/9AT under a 10/1000 µs surge?
The 1.5SMC16CA-M3/9AT has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current of 66.7 A with a 10/1000 µs waveform. This value is measured per Fig. 1 in Vishay document 88303 and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The 1.5SMC16CA-M3/9AT maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C) with minimal derating up to 125 °C.
Is the 1.5SMC16CA-M3/9AT AEC-Q101 qualified?
No, the 1.5SMC16CA-M3/9AT is not AEC-Q101 qualified. Its M3 suffix indicates halogen-free, RoHS-compliant commercial-grade construction. For AEC-Q101 qualification, Vishay offers the HM3 variant (e.g., 1.5SMC16CAHM3_A/I), which includes additional stress testing and traceability for automotive applications. The 1.5SMC16CA-M3/9AT remains suitable for industrial and consumer use where automotive qualification is not mandated.
What does the "CA" suffix mean in 1.5SMC16CA-M3/9AT?
The "CA" suffix in 1.5SMC16CA-M3/9AT denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both forward and reverse directions. Unlike unidirectional "A" variants (e.g., 1.5SMC16A), the CA version has no polarity marking and can be placed without orientation concern. This makes the 1.5SMC16CA-M3/9AT ideal for protecting AC-coupled signals, differential buses like CAN or RS-485, and floating power rails where voltage polarity reversal may occur.
What is the thermal resistance of the 1.5SMC16CA-M3/9AT?
The 1.5SMC16CA-M3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, per Vishay document 88303. This value assumes still air conditions and defines the temperature rise above ambient per watt of steady-state power dissipation. For pulsed operation, thermal impedance curves (Fig. 5) show significantly lower effective resistance during short-duration surges.
Can the 1.5SMC16CA-M3/9AT replace a unidirectional TVS in an existing design?
Yes, the 1.5SMC16CA-M3/9AT can replace a unidirectional TVS in most cases, provided the circuit does not rely on DC blocking or rectification functionality. As a bidirectional device, it clamps equally in both polarities - beneficial for AC or floating nodes - but exhibits identical leakage and clamping behavior as its unidirectional counterpart at the same VWM. However, verify that system-level polarity constraints (e.g., bias networks) remain valid, since the 1.5SMC16CA-M3/9AT lacks cathode marking and conducts symmetrically.
