Product details
Overview
SM1615C/TR13 from Microsemi (now Microchip) is a bidirectional 8-line transient voltage suppressor (TVS) diode array in SO-16 package, rated for 300 W peak pulse power (8/20 µs), 15 V standoff voltage (VWM), 16.7 V minimum breakdown (VBR), and 30 V clamping at 5 A - designed to protect 3.3–24 V low-voltage interfaces including DRAM, SRAM, and HSIC I/O transceivers against ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and lightning-induced surges.
For engineers reviewing the SM1615C/TR13 datasheet, SM1615C/TR13 pinout, SM1615C/TR13 application, or SM1615C/TR13 equivalent, this device serves as board-level surge protection for high-speed digital I/O with verified 200 pF line capacitance, -55°C to +150°C operation, UL 94V-0 molding, and tape-and-reel packaging per EIA-481-1-A standard.
Technical Context
The SM1615C/TR13 implements eight independent, symmetrically configured bidirectional TVS diodes in a single SO-16 package - each channel provides clamping action above ±16.7 V with sub-1 µA leakage at 15 V standoff. Its design targets low-capacitance protection of parallel data buses and multi-line interfaces without signal integrity degradation.
It operates across full industrial temperature range (-55°C to +150°C), supports <0.01% pulse repetition rate, and meets IEC 61000-4-2 Level 4 (±15 kV contact / ±20 kV air) and IEC 61000-4-4 (4 kV EFT) requirements when properly laid out on PCB with short trace paths and ground plane coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VWM) | 15 V - ensures no conduction during normal 3.3–24 V interface operation |
| Breakdown Voltage (VBR) | Min 16.7 V @ 1 mA - defines reliable turn-on threshold for transient suppression |
| Clamping Voltage (VC) | 30 V @ 5 A - limits downstream voltage stress during 8/20 µs surge events |
| Peak Pulse Power | 300 W (8/20 µs) - sustains high-energy transients without failure |
| Line Capacitance | 200 pF @ 1 MHz, 0 V - preserves signal integrity on moderate-speed digital lines |
| Operating Temperature | -55°C to +150°C - supports deployment in automotive under-hood and industrial control environments |
| Leakage Current | ≤1 µA @ 15 V - avoids loading of low-power CMOS/SRAM I/O circuits |
Pinout & Package
Molded SO-16 surface-mount package, UL 94V-0 compliant, 0.128 g weight, pin #1 identified by dot marking on top surface.

|---|---|---|
| 1, 3, 5, 7, 9, 11, 13, 15 | I/O Line Anode/Cathode Pair | Bidirectional TVS path per line - pins are symmetrical; each pair protects one signal line |
| 2, 4, 6, 8, 10, 12, 14, 16 | Common Cathode Bus | Shared low-impedance return path to ground plane - requires low-inductance connection |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15CA | Single-line bidirectional TVS, DO-214AC package, 400 W peak power, 24.4 V clamping @ 5 A | Requires 8 discrete devices for same channel count; higher layout area and inductance | Choose SMAJ15CA only when discrete placement or higher single-line power rating is required |
| SP1003-010 | 8-line unidirectional TVS array, SO-16, 10 V standoff, 120 pF capacitance, 20 V clamping @ 5 A | Limited to unidirectional DC-biased interfaces; lower clamping but narrower voltage range | Select SP1003-010 for 3.3 V-only systems needing tighter clamping and lower capacitance |
Compared with SMAJ15CA and SP1003-010, the SM1615C/TR13 uniquely delivers 8-channel bidirectional protection at 15 V standoff in a single SO-16 footprint - balancing clamping performance, line count density, and compatibility with mixed-voltage (3.3–24 V) board-level I/O protection schemes.

FAQ
What is the standoff voltage rating of the SM1615C/TR13?
The SM1615C/TR13 has a standoff voltage (VWM) of 15 V, meaning it remains non-conductive under continuous operating voltages up to 15 V. This allows safe integration into 3.3 V, 5 V, 12 V, and 24 V digital interfaces without leakage or false triggering. The SM1615C/TR13 is specifically rated to protect circuits operating within that range while clamping transients above 16.7 V.
Is the SM1615C/TR13 bidirectional or unidirectional?
The SM1615C/TR13 is a bidirectional TVS array, as confirmed by its "C" suffix per the manufacturer's documentation. Each of its eight channels conducts symmetrically for both positive and negative transients - making it suitable for AC-coupled, differential, or floating I/O lines such as USB, RS-485, and HSIC. The SM1615C/TR13 does not require polarity-aware routing.
What is the clamping voltage of the SM1615C/TR13 at 5 A?
The SM1615C/TR13 clamps to a maximum of 30 V at 5 A for an 8/20 µs current waveform, as specified in the electrical characteristics table. This value ensures downstream ICs see limited overvoltage stress during surge events. The SM1615C/TR13 maintains this clamping performance across its full operating temperature range and after repeated transient exposure.
Does the SM1615C/TR13 meet IEC 61000-4-2 ESD immunity standards?
Yes - the SM1615C/TR13 is designed to meet IEC 61000-4-2 Level 4 (±15 kV contact discharge, ±20 kV air discharge) when implemented with proper PCB layout: short traces, low-inductance ground connections, and placement at the board edge. Its 300 W peak power rating and fast response time enable reliable ESD energy diversion. The SM1615C/TR13 datasheet confirms compliance under these test conditions.
What package type and pin count does the SM1615C/TR13 use?
The SM1615C/TR13 uses a molded SO-16 surface-mount package with 16 pins, conforming to JEDEC MS-012 standards. Pin #1 is marked by a dot on the top surface. The package is UL 94V-0 rated and weighs approximately 0.128 g. The SM1615C/TR13 shares identical mechanical dimensions and thermal characteristics with other members of the SM16xx family.
