Product details
Overview
SMPC8.0A-M3/87A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the eSMP® Series, designed for clamping inductive-switching transients on power rails and signal lines. It features a 8.0 V stand-off voltage (VWM), 13.6 V maximum clamping voltage (VC) at 50 A IPPM, 1500 W peak pulse power (10/1000 μs), and operates within -55 °C to +150 °C junction temperature range. Used to protect MOSFETs and sensor ICs in automotive body electronics.
For engineers reviewing the SMPC8.0A-M3/87A datasheet, SMPC8.0A-M3/87A pinout, SMPC8.0A-M3/87A application, or SMPC8.0A-M3/87A equivalent, key selection criteria include unidirectional polarity, TO-277A (SMPC) package compatibility, 1.25 W steady-state power dissipation, MSL Level 1 reflow capability, and AEC-Q101 qualification eligibility via HM3 suffix variants.
Technical Context
This TVS diode employs silicon avalanche technology to provide fast response (<1 ns) to transient overvoltages while maintaining low incremental surge resistance. Its dual-anode configuration (SMPCxxA series) enables symmetrical mounting with cathode band orientation defining polarity - critical for correct placement on DC-biased lines.
The device is rated per ANSI/IEEE C62.35 and tested using standardized 10/1000 μs surge waveforms. Thermal performance is characterized per JEDEC 51-2A (RθJA = 100 °C/W max) and JEDEC 51-14 (RθJM = 3 °C/W max), supporting reliable operation when mounted on FR4 PCBs with 2 oz copper and standard footprint.

IC Role / Device Role / Timing Role: Fast-response unidirectional clamp on DC bus (e.g., +48 V telecom rail), referenced to chassis ground. Use Value: 8.0 V VWM allows clean operation under nominal 48 V ±10 % regulation; 13.6 V VC prevents overvoltage on downstream DC-DC controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A-E3/5A | Same VWM (8.0 V) and VC (13.6 V), but SMA package (higher RθJA = 140 °C/W), lower PPPM (400 W). | Limited to lower-energy transients; unsuitable for automotive load-dump where 1500 W is required. | Select SMPC8.0A-M3/87A when board space permits and higher surge robustness is mandatory. |
| SMCJ8.0A-M3/87A | Same SMPC package and 1500 W PPPM, but higher VBR (8.89–9.83 V vs. 8.89–9.83 V identical), same VC (13.6 V). | Functionally identical clamping behavior; differs only in packaging suffix and reel quantity (6500 pcs vs. 1500 pcs for /86A). | SMCJ8.0A-M3/87A is not a valid alternative - it is a misidentified part; SMPC8.0A-M3/87A has no direct drop-in replacement in SMCJ series due to different base P/N structure. |
Compared with SMAJ8.0A-E3/5A, SMPC8.0A-M3/87A delivers 275 % higher peak pulse power in the same footprint class and enables automotive-grade reliability via MSL Level 1 and optional AEC-Q101 qualification path; no true pin-compatible alternative exists in the 1500 W SMPC family.

FAQ
What is the clamping voltage of SMPC8.0A-M3/87A at its rated peak pulse current?
The SMPC8.0A-M3/87A exhibits a maximum clamping voltage (VC) of 13.6 V when subjected to its rated peak pulse current (IPPM) of 50 A under the standard 10/1000 μs waveform. This value is measured at TJ = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events. The SMPC8.0A-M3/87A maintains this clamping performance across its qualified operating temperature range.
Is SMPC8.0A-M3/87A suitable for automotive applications requiring AEC-Q101 qualification?
No - SMPC8.0A-M3/87A carries the industrial-grade M3 suffix and is not AEC-Q101 qualified. For automotive use, select the HM3-suffixed variant (e.g., SMPC8.0AHM3/87A), which is explicitly qualified per AEC-Q101 and marked with "HM3" in the ordering code. The SMPC8.0A-M3/87A shares identical electrical specs but lacks the extended reliability testing required for automotive deployment.
What does the /87A package code indicate for SMPC8.0A-M3/87A?
For SMPC8.0A-M3/87A, the /87A suffix denotes a 13-inch diameter plastic tape-and-reel packaging format containing 6500 units per reel. This contrasts with /86A, which specifies a 7-inch reel holding 1500 units. Both /86A and /87A are compatible with standard SMT pick-and-place equipment and meet JEDEC MSL Level 1 handling requirements.
How does the dual-anode configuration of SMPC8.0A-M3/87A affect PCB layout?
The SMPC8.0A-M3/87A features two electrically parallel anode terminals (Anode 1 and Anode 2) that must be connected to the same net - typically the protected power rail. This configuration improves current sharing and thermal distribution during surge events. Layout requires symmetric copper pours and equal trace lengths to both anodes to maintain balance; the cathode band identifies the singular cathode terminal for grounding.
What is the maximum steady-state power dissipation for SMPC8.0A-M3/87A at room temperature?
The SMPC8.0A-M3/87A has a maximum steady-state power dissipation (PD) of 1.25 W at TA = 25 °C when mounted on a standard FR4 PCB with 2 oz copper and the recommended footprint. Derating is required above 25 °C per Figure 2 in the datasheet; at 70 °C ambient, PD drops to approximately 0.75 W. This rating applies only to continuous DC or low-frequency conditions - not transient surges.
