Product details
Overview
1.5SMC16A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal 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, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the 1.5SMC16A-E3/57T datasheet, 1.5SMC16A-E3/57T pinout, 1.5SMC16A-E3/57T application, or 1.5SMC16A-E3/57T equivalent, key selection criteria include unidirectional polarity, 1500 W surge capability, 22.5 V clamping under 66.7 A transient, RoHS-compliant matte tin terminals, and MSL Level 1 moisture sensitivity for reflow compatibility.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (15.2–16.8 V). Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of ESD, lightning-induced surges, and inductive switching spikes on DC rails and low-speed signal paths.
The 1.5SMC16A-E3/57T is rated for 150 °C maximum junction temperature, exhibits 0.086 %/°C temperature coefficient of VBR, and is characterized with 75 °C/W junction-to-ambient thermal resistance on standard 8.0 mm × 8.0 mm copper pads - confirming suitability for high-reliability board-level surge protection without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC bias margin. |
| VBR (Breakdown) | 15.2–16.8 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above normal operating rail. |
| VC (Clamping) | 22.5 V at 66.7 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case surge; limits stress on downstream components. |
| PPPM | 1500 W - Peak pulse power handling capacity; supports robust protection against IEC 61000-4-5 Level 4 surges. |
| IPPM | 66.7 A - Maximum non-repetitive surge current; determines minimum trace width and PCB layout robustness. |
| TJ max. | 150 °C - Maximum junction temperature; enables operation in under-hood automotive or enclosed industrial enclosures. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with automated pick-and-place. |
Pinout & Package
SMC (DO-214AB) package with two terminals: cathode marked by a band on the body; anode unmarked. Matte tin-plated leads meet J-STD-002 solderability and JESD 22-B102 reliability standards. MSL Level 1 rating allows unlimited floor life before reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased terminal | Connected to protected line (e.g., +12 V rail); conducts avalanche current to ground during overvoltage events. |
| Anode | Reference/ground terminal | Typically tied to system ground or low-impedance return path; completes clamping loop with minimal inductance. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Enables compliance with IEC 61000-4-5 surge immunity requirements up to 4 kV (line-earth) in compact SMC form factor. |
| 22.5 V clamping voltage at 66.7 A | Keeps protected ICs (e.g., microcontrollers, CAN transceivers) within absolute maximum ratings during transient events. |
| Glass passivated chip junction | Ensures stable VBR and low leakage over temperature and lifetime; critical for long-term reliability in automotive applications. |
| RoHS-compliant, matte tin terminals | Supports lead-free reflow (260 °C peak) without solder joint degradation or whisker growth (JESD 201 Class 2). |
| AEC-Q101 qualified variant available | HE3 suffix versions meet automotive-grade qualification; this E3/57T part shares identical electrical specs and package. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/52 | Same VWM (13.6 V), VC = 24.4 V at 61.5 A; lower PPPM (600 W); SMB package (smaller footprint, higher RθJA). | Lower surge rating suits consumer-grade or space-constrained designs where 1500 W is not required. | Select when board area is limited and surge threat level is ≤ IEC 61000-4-5 Level 3. |
| 1.5KE16A | Through-hole DO-201 package; same VWM/VBR/VC; identical 1500 W rating but larger size and manual assembly requirement. | Used where legacy through-hole manufacturing or higher mechanical robustness is prioritized over SMT automation. | Choose for prototyping, repair, or high-vibration environments where SMT solder joint reliability is a concern. |
Compared with SMBJ16A-E3/52 and 1.5KE16A, the 1.5SMC16A-E3/57T delivers identical clamping performance in a surface-mount SMC package optimized for automated production, offering superior thermal dissipation over SMBJ and smaller footprint than 1.5KE - making it ideal for volume automotive and industrial PCBs requiring AEC-Q101-compatible surge protection.

FAQ
What is the maximum clamping voltage of the 1.5SMC16A-E3/57T under a 10/1000 μs surge?
The 1.5SMC16A-E3/57T has a maximum clamping voltage (VC) of 22.5 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 66.7 A. This value is measured per standard test conditions (TA = 25 °C, mounted on 8.0 mm × 8.0 mm copper pads) and defines the upper voltage limit imposed on protected circuits during surge events. The 1.5SMC16A-E3/57T maintains this clamping performance consistently across its specified operating temperature range.
Is the 1.5SMC16A-E3/57T RoHS-compliant and lead-free compatible?
Yes, the 1.5SMC16A-E3/57T carries the "E3" suffix, indicating full RoHS compliance and compatibility with lead-free reflow soldering processes up to a peak temperature of 260 °C. Its matte tin-plated terminals meet J-STD-002 solderability requirements and JESD 22-B102 for intermetallic reliability. The 1.5SMC16A-E3/57T also satisfies JESD 201 Class 2 whisker resistance testing, ensuring long-term solder joint integrity in commercial and industrial applications.
Does the 1.5SMC16A-E3/57T have AEC-Q101 qualification?
The base 1.5SMC16A-E3/57T is not AEC-Q101 qualified; however, Vishay offers the functionally identical 1.5SMC16AHE3_A variant (with HE3 suffix) which is fully AEC-Q101 qualified for automotive applications. Both share identical electrical characteristics, package dimensions, and thermal performance - only differing in qualification documentation and traceability. For automotive production, specify 1.5SMC16AHE3_A/H or 1.5SMC16AHE3_A/I depending on reel size requirements.
What is the thermal resistance of the 1.5SMC16A-E3/57T, and how does it affect layout?
The 1.5SMC16A-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 8.0 mm × 8.0 mm copper pads per terminal. This value assumes standard FR-4 PCB construction and natural convection. To maintain safe junction temperatures under repetitive surge conditions, designers must ensure adequate copper area and avoid excessive trace length between the 1.5SMC16A-E3/57T and ground/power planes to minimize thermal and inductive impedance.
How does the 1.5SMC16A-E3/57T differ from bidirectional variants like 1.5SMC16CA?
The 1.5SMC16A-E3/57T is unidirectional, meaning it conducts only in reverse bias (cathode positive) and blocks forward current - ideal for DC rail protection. In contrast, 1.5SMC16CA is bidirectional, providing symmetrical clamping for AC or differential signal lines. Both share identical VWM, VBR, and VC magnitudes, but the 1.5SMC16A-E3/57T lacks marking on the anode end and requires correct polarity orientation during placement, whereas the 1.5SMC16CA has no polarity marking and clamps equally in both directions.
