Product details
Overview
SM16LC05CE3/TR13 from Microsemi (now Microchip) is a bidirectional 8-line TVS diode array in SO-16 package, designed for board-level ESD/EFT protection of 5 V logic interfaces. It features 300 W peak pulse power (8/20 µs), 6 V minimum breakdown voltage, 9.8 V clamping at 1 A, 20 µA max leakage at 5 V, and 25 pF typical capacitance per line - deployed in I/O transceivers, industrial control I/O modules, and low-voltage data buses.
For engineers reviewing the SM16LC05CE3/TR13 datasheet, SM16LC05CE3/TR13 pinout, SM16LC05CE3/TR13 application, or SM16LC05CE3/TR13 equivalent, key selection criteria include standoff voltage matching (5.0 V), bidirectional clamping capability, SO-16 footprint compatibility, sub-10 V clamping at 1 A, and ≤25 pF line capacitance for high-speed signal integrity.
Technical Context
This device implements eight independent, electrically isolated bidirectional TVS diodes in a single SO-16 surface-mount package. Each channel provides symmetrical clamping above ±6 V breakdown and limits transient voltages to ≤11 V at 5 A per line under IEC 61000-4-2/4-4 stress conditions.
It operates across –55 °C to +150 °C and meets UL 94V-0 flammability rating. The array is optimized for protecting 3.3 V to 24 V systems, with specific design validation for DRAM, SRAM, CMOS, HCMOS, and HSIC interfaces up to 24 V DC operating voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VWM) | 5.0 V - matches nominal 5 V supply rails; ensures no conduction during normal operation |
| Breakdown Voltage (VBR) | Min 6.0 V @ 1 mA - triggers clamping only after overvoltage exceeds safe margin |
| Clamping Voltage (VC) | 9.8 V @ 1 A - limits transient excursion to safe level for 5 V logic inputs |
| Peak Pulse Power | 300 W (8/20 µs) - withstands IEC 61000-4-2 Level 4 (±15 kV contact) surges |
| Line Capacitance | 25 pF @ 1 MHz, 0 V - supports signal integrity on USB 1.1, RS-485, and parallel bus interfaces |
| Leakage Current | ≤20 µA @ 5 V - avoids loading of high-impedance 5 V I/O lines |
| Operating Temp Range | –55 °C to +150 °C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
Molded SO-16 surface-mount package, UL 94V-0 rated, 0.128 g weight, pin #1 identified by dot marking. Body marked "MAB" per device marking convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 9, 11, 13, 15 | Anode/Cathode pair input | Eight independent bidirectional I/O protection channels - each pin pair (odd/even) forms one protected line |
| 2, 4, 6, 8, 10, 12, 14, 16 | Common cathode/anode reference | Shared ground-return path for all eight channels; requires low-inductance PCB connection to system GND |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping per line | Enables protection of AC-coupled or differential signals without polarity constraints |
| Electrically isolated channels | Prevents cross-talk or failure propagation between protected I/O lines |

Applications
| Industrial I/O Protection | USB 1.1 Interface Protection |
|---|---|
Use Scenario: Protecting digital input/output terminals on programmable logic controllers against ESD from operator interaction and field wiring transients. IC Role / Device Role / Timing Role: Board-level transient suppressor placed directly at connector entry point before signal conditioning circuitry. Use Value: Clamps 15 kV contact ESD events to <11 V, preserving integrity of 5 V microcontroller GPIO and optocoupler drivers. | Use Scenario: Safeguarding upstream/downstream D+ and D− lines of full-speed USB 1.1 ports in embedded host devices. IC Role / Device Role / Timing Role: Low-capacitance TVS array placed adjacent to USB connector to minimize stub length and preserve signal rise/fall times. Use Value: 25 pF per line maintains USB 1.1 eye diagram compliance while suppressing ±8 kV IEC 61000-4-2 transients. |
| RS-485 Transceiver Protection | DRAM/SRAM Data Bus Protection |
Use Scenario: Shielding half-duplex RS-485 transceiver pins (A/B/RE/DE) in factory automation gateways exposed to cable-induced surges.

Use Value: Symmetrical ±6 V breakdown and 9.8 V clamping ensure common-mode and differential-mode surge suppression without signal distortion. | Use Scenario: Guarding parallel address/data bus lines connecting microcontrollers to external memory in medical imaging subsystems. IC Role / Device Role / Timing Role: Per-line protection placed at memory socket edge to intercept fast-rising ESD pulses before reaching CMOS inputs. Use Value: 20 µA leakage at 5 V prevents DC loading of high-impedance DRAM address latches; 300 W rating handles board-level lightning-induced surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Single-line unidirectional TVS; 5.0 V standoff; 9.2 V clamping @ 1 A; 100 pF capacitance | Requires eight discrete devices and additional routing; unsuitable for high-speed buses due to higher capacitance | Use only when space allows discrete placement and signal speed <1 Mbps |
| SP1003-05UTG | 8-line bidirectional array; 5.0 V standoff; 12 V clamping @ 1 A; 0.5 pF capacitance; SOT-23-8 package | Lower capacitance enables USB 2.0/3.0 support but lower 150 W peak power limits surge robustness | Select when ultra-low capacitance is critical and surge threat is limited to IEC 61000-4-2 Level 2 |
Compared with SMAJ5.0A and SP1003-05UTG, SM16LC05CE3/TR13 delivers balanced performance: SO-16 integration reduces PCB area vs. discretes, 25 pF supports legacy high-speed interfaces better than SMAJ5.0A, and 300 W rating exceeds SP1003-05UTG's 150 W for harsh industrial environments.

FAQ
What is the standoff voltage rating of SM16LC05CE3/TR13 and how does it relate to 5 V system protection?
The SM16LC05CE3/TR13 has a 5.0 V standoff voltage (VWM), meaning it remains non-conductive below this threshold. This matches standard 5 V logic rails and ensures no interference during normal operation while triggering clamping only during overvoltage events. Its 6.0 V minimum breakdown provides a 1 V safety margin above VWM, making SM16LC05CE3/TR13 appropriate for reliable 5 V interface protection without false triggering.
Is SM16LC05CE3/TR13 suitable for protecting high-speed interfaces like USB or RS-485?
Yes - SM16LC05CE3/TR13 offers 25 pF typical capacitance per line at 1 MHz and 0 V bias, which preserves signal integrity on full-speed USB 1.1 (12 Mbps) and RS-485 (up to 10 Mbps) links. Its bidirectional architecture and low clamping voltage (9.8 V @ 1 A) prevent data corruption during ESD events. For USB 2.0 or faster, lower-capacitance alternatives should be evaluated, but SM16LC05CE3/TR13 remains valid for legacy and cost-sensitive high-speed implementations.
How many protected lines does SM16LC05CE3/TR13 provide, and how are they arranged in the SO-16 package?
SM16LC05CE3/TR13 protects eight independent bidirectional lines using all 16 pins of the SO-16 package: pins 1–15 (odd-numbered) serve as line inputs, and pins 2–16 (even-numbered) form the common reference path. This configuration enables compact, single-package protection of parallel buses or multi-signal interfaces without external grounding complexity. Each channel is electrically isolated, preventing fault propagation between lines.
Does SM16LC05CE3/TR13 meet international ESD and surge immunity standards?
Yes - SM16LC05CE3/TR13 is characterized for IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and secondary lightning effects. Its 300 W peak pulse power (8/20 µs) supports Level 4 (±15 kV contact) ESD testing, and its clamping behavior is validated per Figure 2 in the MSC0884 datasheet. The device is also rated for operation from –55 °C to +150 °C, supporting deployment in equipment certified to industrial and automotive environmental standards.
What is the marking code for SM16LC05CE3/TR13 and how is pin 1 identified on the package?
The SM16LC05CE3/TR13 is marked "MAB" on the top surface of the SO-16 body, per the manufacturer's device marking convention. Pin 1 is identified by a small dot located adjacent to the lead on the top side of the package. This marking aligns with EIA-481 tape-and-reel packaging and ensures correct orientation during automated placement. The "E3/TR13" suffix indicates lead-free (E3) and 13-inch tape-and-reel (TR13) packaging per Microsemi's ordering nomenclature.
