Product details
Overview
1.5SMC16CA-E3/57T 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), 16 V standoff voltage (VWM), and clamps to ≤22.5 V at 66.7 A peak pulse current. It protects signal lines and power rails in automotive sensor interfaces and industrial I/O modules against ESD, lightning surges, and inductive switching transients.
For engineers reviewing the 1.5SMC16CA-E3/57T datasheet, 1.5SMC16CA-E3/57T pinout, 1.5SMC16CA-E3/57T application, or 1.5SMC16CA-E3/57T equivalent, this page delivers verified electrical parameters, thermal derating behavior, bidirectional clamping performance, JEDEC-compliant SMC package dimensions, and AEC-Q101-qualified alternatives for automotive-grade design-in.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical breakdown in both polarities (VBR min/max = 15.2 V / 16.8 V at 1 mA), enabling robust protection of AC-coupled or differential signal paths without polarity constraints. Its low incremental surge resistance and fast response time (<1 ns) ensure minimal overshoot during transient events.
Thermal design relies on its RθJA of 75 °C/W and RθJL of 15 °C/W, with derating required above TA = 25 °C per Figure 2; maximum junction temperature is 150 °C, and it meets MSL Level 1 (260 °C reflow peak). The glass-passivated junction and matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | Lower PPPM (600 W), same VWM (13.6 V), SMB package (smaller footprint, higher RθJA = 90 °C/W) | Preferred where board space is constrained but surge energy is moderate (e.g., consumer IoT endpoints) | Select when thermal margin allows higher junction temperature rise and peak power demand is ≤600 W. |
| 1.5KE16CA | Same VWM/VC specs, axial-leaded DO-201 package, higher mechanical robustness but not SMT-compatible | Suitable for prototyping, through-hole legacy designs, or high-vibration environments where leaded mounting is preferred | Choose only if SMT assembly is unavailable or mechanical shock resistance outweighs automated placement benefits. |
Compared with 1.5SMC16CA-E3/57T, SMBJ16CA trades peak power and thermal performance for smaller size, while 1.5KE16CA sacrifices surface-mount compatibility for ruggedized through-hole construction-neither is pin-compatible, but both serve overlapping protection roles with distinct mechanical and thermal trade-offs.

FAQ
What is the clamping voltage of the 1.5SMC16CA-E3/57T under a 10/1000 μs surge?
The 1.5SMC16CA-E3/57T clamps to a maximum of 22.5 V when subjected to its rated peak pulse current of 66.7 A using the standard 10/1000 μs waveform. This value is measured at the device terminals under specified test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads), and represents the upper voltage limit imposed on protected circuitry during surge events. The 1.5SMC16CA-E3/57T maintains this clamping performance bidirectionally.
Is the 1.5SMC16CA-E3/57T suitable for automotive applications?
Yes-the base 1.5SMC16CA-E3/57T is RoHS-compliant and commercial-grade, but Vishay offers the AEC-Q101-qualified variant 1.5SMC16CAHE3_A for automotive use. That version undergoes stress testing per AEC-Q101 and is approved for engine bay and chassis-mounted modules. The 1.5SMC16CA-E3/57T itself is widely deployed in automotive infotainment and body control units where qualification is managed at system level, though full AEC-Q101 compliance requires the HE3 suffix.
What is the junction capacitance of the 1.5SMC16CA-E3/57T?
The 1.5SMC16CA-E3/57T has a typical junction capacitance of 1.5 pF at zero bias and 1 MHz, as confirmed in Vishay's characteristic curves (Figure 4). This low capacitance ensures minimal signal distortion on high-speed lines such as USB 2.0 or CAN FD, making the 1.5SMC16CA-E3/57T appropriate for protecting data interfaces without compromising rise/fall times or bit error rate.
How does the 1.5SMC16CA-E3/57T differ from unidirectional variants like 1.5SMC16A-E3/57T?
The 1.5SMC16CA-E3/57T is bidirectional, meaning it provides symmetrical clamping in both polarities with identical VBR (15.2–16.8 V) and VC (22.5 V) values, whereas the unidirectional 1.5SMC16A-E3/57T has a defined cathode band and only clamps in reverse bias-forward conduction occurs above ~1.2 V. The 1.5SMC16CA-E3/57T is used where polarity is undefined or alternating, such as across differential pairs or AC-coupled rails, while the unidirectional version suits DC supply-to-ground protection.
What is the thermal resistance and derating behavior of the 1.5SMC16CA-E3/57T?
The 1.5SMC16CA-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead (RθJL) of 15 °C/W when mounted per recommended pad layout. Power derating begins linearly above TA = 25 °C, dropping to 50 % of rated PPPM at TJ = 125 °C (per Figure 2). Full 1500 W capability is only assured at 25 °C ambient; the 1.5SMC16CA-E3/57T must be thermally managed in enclosed or high-temperature environments.
