Product details
Overview
SMPC13A-M3/87A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the eSMP® SMPC (TO-277A) package, designed for robust overvoltage protection of sensitive electronics. It features a 13.0 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR), 21.5 V maximum clamping voltage (VC) at 1.0 A peak pulse current, and 1500 W peak pulse power (PPPM) with 10/1000 μs waveform - ideal for protecting MOSFETs and signal lines in automotive and industrial control systems.
For engineers reviewing the SMPC13A-M3/87A datasheet, SMPC13A-M3/87A pinout, SMPC13A-M3/87A application, or SMPC13A-M3/87A equivalent, key selection criteria include unidirectional polarity, low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, halogen-free RoHS-compliant construction, and compatibility with automated SMT placement on FR4 PCBs with 2 oz copper.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below its 13.0 V stand-off voltage and rapidly transitions to low-impedance conduction above its 14.4–15.9 V breakdown threshold. Its design targets transient suppression from inductive load switching and ESD events, with fast response time and low incremental surge resistance enabling effective protection without affecting normal circuit operation.
The SMPC13A-M3/87A uses a dual-anode/single-cathode configuration (Anode 1, Anode 2, Cathode) in the SMPC (TO-277A) package, where the cathode band denotes polarity. Thermal performance is characterized by RθJA ≤ 100 °C/W (FR4, 2 oz) and RθJM ≤ 3.0 °C/W, supporting reliable operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.0 V - maximum reverse voltage before significant leakage; defines safe operating margin below breakdown |
| VBR min/max | 14.4 V / 15.9 V at 1.0 mA - precise breakdown onset ensures predictable clamping activation |
| VC @ IPPM | 21.5 V at 1.0 A - limits voltage seen by protected IC/MOSFET during surge, minimizing stress |
| PPPM | 1500 W (10/1000 μs) - high energy absorption capacity for repetitive or single-event transients |
| Package | SMPC (TO-277A) - ultra-low profile (1.1 mm typical height), optimized for space-constrained SMT layouts |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct cathode orientation |
| MSL Level | Level 1 per J-STD-020 - no dry-pack or bake required prior to reflow; supports standard assembly flow |
Pinout & Package
SMPC13A-M3/87A is housed in the SMPC (TO-277A) surface-mount package - a 3-terminal, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102, meeting UL 94 V-0 flammability rating. The cathode band identifies the cathode terminal; polarity must be observed during PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Primary anode connection | One of two parallel anode terminals; connects to protected line or ground return path |
| Anode 2 | Secondary anode connection | Electrically tied to Anode 1 internally; enables higher surge current handling via dual-path layout |
| Cathode | Clamping output node | Connected to system ground or reference rail; carries full surge current during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile | 1.1 mm typical height - enables use in ultra-thin consumer and automotive modules |
| Automated placement compatible | Standard 13" tape-and-reel packaging (/87A code) - supports high-speed pick-and-place with zero manual handling |
| Low incremental surge resistance | Enables tighter clamping (21.5 V VC) under 1.0 A surge - reduces voltage overshoot on protected nodes |
| AEC-Q101 qualification | Not applicable to SMPC13A-M3/87A (AEC-Q101 applies only to SMPC22AN–SMPC85AN variants) |
| Halogen-free & RoHS | M3 suffix confirms compliance - meets environmental requirements for industrial and commercial end equipment |
Applications
| Automotive Power Window Control | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting microcontroller GPIO and H-bridge driver inputs from inductive kickback when DC motors are switched off. IC Role / Device Role / Timing Role: Unidirectional TVS placed between motor drive line and ground, clamping transients before they reach logic-level components. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V MCU I/O pins by limiting transient voltage to ≤21.5 V during 1.0 A surges. | Use Scenario: Safeguarding analog input channels (e.g., 4–20 mA sensor loops) from lightning-induced surges in factory-floor environments. IC Role / Device Role / Timing Role: Front-end transient suppressor on signal conditioning PCB, mounted directly at connector entry point. Use Value: Maintains signal integrity by suppressing >1 kV transients while adding <1 nA leakage at 13 V - no impact on measurement accuracy. |
| Consumer Appliance Motor Drive | Telecom Base Station Power Rails |
Use Scenario: Shielding BLDC motor controller FET gates from voltage spikes generated during PWM commutation. IC Role / Device Role / Timing Role: Localized TVS across gate-source terminals or supply rails near power stage. Use Value: Enables reliable operation at 150 °C junction temperature with 1500 W peak power handling - eliminates need for derating in enclosed enclosures. | Use Scenario: Secondary-level protection on +12 V and +48 V backplane rails against ESD and coupling from adjacent RF sections. IC Role / Device Role / Timing Role: Standoff-rated clamp on distributed power distribution network, placed near DC-DC converter inputs. Use Value: Provides 13.0 V nominal hold-off with 21.5 V clamping - preserves upstream regulator stability while absorbing 10/1000 μs surges up to 1500 W. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/52 | Same VWM (13 V), but SMB package (higher profile: 2.3 mm); 600 W PPPM vs. 1500 W | Limited to lower-energy transients; less suitable for high-current inductive loads | Select when board height budget allows ≥2.3 mm and surge energy is ≤600 W |
| SMCJ13A | Same VWM and TO-277A package, but higher VC (23.2 V) and 3000 W PPPM; larger die area | Better for high-energy surges but increases protected node voltage stress during clamping | Choose when system can tolerate 23.2 V clamping and requires >1500 W capability |
Compared with SMBJ13A-E3/52 and SMCJ13A, the SMPC13A-M3/87A delivers optimal balance of ultra-low profile (1.1 mm), 1500 W surge capacity, and tight 21.5 V clamping - making it preferred for space-constrained, medium-energy protection in automotive and industrial edge nodes.

FAQ
What is the clamping voltage of SMPC13A-M3/87A and how is it measured?
The SMPC13A-M3/87A has a maximum clamping voltage (VC) of 21.5 V, measured at 1.0 A peak pulse current using a 10/1000 μs waveform per Figure 1 in Vishay Document 89116. This value reflects the voltage across the device during surge conduction and defines the upper limit imposed on protected circuitry - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is SMPC13A-M3/87A AEC-Q101 qualified?
No, SMPC13A-M3/87A is not AEC-Q101 qualified. Per Vishay documentation, AEC-Q101 qualification applies only to SMPC22AN through SMPC85AN variants (ordering codes with HM3 suffix). The SMPC13A-M3/87A carries the industrial-grade M3 suffix and meets RoHS, halogen-free, and J-STD-020 MSL Level 1 requirements.
What does the /87A suffix indicate in SMPC13A-M3/87A?
Per Vishay's ordering information, the /87A suffix specifies the packaging format: 13-inch diameter plastic tape-and-reel with 6500 units per reel. This contrasts with /86A (7-inch reel, 1500 units). Both /86A and /87A are available for SMPC5.0A-M3 through SMPC36A-M3, and both support standard SMT assembly processes.
How does the dual-anode configuration of SMPC13A-M3/87A improve performance?
The SMPC13A-M3/87A uses two anode terminals (Anode 1 and Anode 2) electrically connected in parallel internally. This configuration lowers effective series resistance and improves current sharing during high-amplitude transients, contributing to its 1500 W peak pulse power rating and low incremental surge resistance - enhancing clamping consistency and thermal distribution.
Can SMPC13A-M3/87A be used in bidirectional protection circuits?
No, SMPC13A-M3/87A is strictly unidirectional and must be oriented with the cathode band toward the protected circuit's ground or reference rail. For bidirectional protection, Vishay offers separate SMPCxxCA variants (not applicable to this part number); using SMPC13A-M3/87A in reverse-biased configurations risks permanent failure due to lack of reverse breakdown specification.
