Product details
Overview
SMPC26AN-M3/I from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in the SMPC (TO-277A) package, rated for 26 V stand-off voltage (VWM), 28.9–31.9 V breakdown voltage (VBR), and 1500 W peak pulse power (PPPM) with 42.1 V clamping voltage at 35.6 A. It protects MOSFETs and ICs against inductive switching transients in automotive and industrial power electronics.
For engineers reviewing the SMPC26AN-M3/I datasheet, SMPC26AN-M3/I pinout, SMPC26AN-M3/I application, or SMPC26AN-M3/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 1.1 mm profile height, MSL Level 1 moisture sensitivity, and thermal resistance (RθJA = 100 °C/W) on FR4 PCB.
Technical Context
This device operates as a silicon avalanche diode designed to clamp transient overvoltages above its VWM of 26 V while maintaining low leakage (<1 μA) below that threshold. Its 1500 W PPPM rating is specified under the standardized 10/1000 μs waveform per ANSI/IEEE C62.35, with clamping performance validated at 35.6 A IPPM.
The SMPC26AN-M3/I uses a dual-anode/single-cathode configuration (Anode 1, Anode 2, Cathode) in the SMPC (TO-277A) package, enabling symmetrical mounting and heat dissipation when cathode is soldered to heatsink. It meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow compatibility up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 26 V - maximum continuous reverse operating voltage before conduction begins |
| VBR min/max | 28.9 V / 31.9 V at 1 mA - guaranteed avalanche initiation range for reliable turn-on margin |
| VC at IPPM | 42.1 V at 35.6 A - clamped voltage during 10/1000 μs surge, limiting stress on protected ICs |
| PPPM | 1500 W - peak transient power handling capability under standardized surge waveform |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJA | 100 °C/W - thermal resistance from junction to ambient on standard FR4 PCB, guiding heatsinking needs |
| Polarity | Unidirectional - blocks reverse current only; requires correct orientation relative to protected circuit |
Pinout & Package
Package: SMPC (TO-277A), surface-mount, 3-terminal, 1.1 mm typical height, halogen-free and RoHS-compliant, with matte tin-plated leads solderable per J-STD-002. Cathode identified by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Primary anode connection | One of two parallel anode terminals; enables low-inductance layout and current sharing |
| Anode 2 | Secondary anode connection | Electrically identical to Anode 1; used jointly to reduce effective series inductance and thermal resistance |
| Cathode | Common cathode terminal | Single cathode node; optimal thermal path when mounted to heatsink or copper pour |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile (1.1 mm) | Enables use in space-constrained automotive ECUs and portable industrial controllers without compromising board clearance |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per AEC specification |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients, improving protection margin for sensitive gate drivers |
| Fast response time | Sub-nanosecond avalanche turn-on ensures clamping occurs before downstream MOSFET or IC damage thresholds are exceeded |
| MSL Level 1 | Allows unlimited floor life and single-reflow processing at 260 °C peak without baking, simplifying SMT line integration |
Applications
| Automotive Power Window Control | Industrial PLC Digital Output Module |
|---|---|
Use Scenario: Protects H-bridge MOSFETs from inductive kickback when driving 12 V DC window motors. IC Role / Device Role / Timing Role: Unidirectional TVS placed across motor terminals to clamp flyback voltage spikes during PWM switching. Use Value: Limits transient voltage to ≤42.1 V, preventing gate oxide rupture in 40 V-rated N-channel MOSFETs while supporting AEC-Q101 compliance. | Use Scenario: Shields 24 V DC solid-state relay outputs from load dump and solenoid de-energization surges in factory automation systems. IC Role / Device Role / Timing Role: Standoff-rated TVS connected between output rail and ground to absorb repetitive 1500 W pulses without degradation. Use Value: Maintains <1 μA leakage at 26 V, ensuring minimal standby current draw and stable logic-level signaling integrity. |
| Telecom Base Station DC Power Input | Consumer Appliance Motor Driver Board |
Use Scenario: Guards primary-side DC/DC converter inputs against lightning-induced surges on -48 V telecom power feeds. IC Role / Device Role / Timing Role: High-power unidirectional suppressor placed upstream of input filter capacitors to divert surge energy to chassis ground. Use Value: Withstands 1500 W peak pulse and 150 °C max junction temperature, enabling robust front-end protection in outdoor cabinet installations. | Use Scenario: Safeguards BLDC motor gate drivers in smart washing machines from commutation transients during high-speed spin cycles. IC Role / Device Role / Timing Role: Low-profile TVS mounted adjacent to half-bridge ICs to minimize trace inductance and improve clamping fidelity. Use Value: 1.1 mm height allows placement under metal shielding cans; dual-anode layout reduces effective clamping impedance by ~30% vs. single-anode equivalents. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ26A-E3/5A | DO-214AC package, 1.5 kW PPPM, 42.1 V VC, but higher RθJA (150 °C/W) and no AEC-Q101 qualification | Lacks automotive qualification and has taller profile (2.3 mm), limiting use in space- and reliability-critical modules | Acceptable for industrial non-automotive designs where footprint and qualification are not constraints |
| SMCJ26A | DO-214AB package, same 26 V VWM and 42.1 V VC, but larger body (7.11 × 6.22 mm), 1.7 mm height, and no M3 suffix halogen-free assurance | Higher thermal mass improves surge endurance but incompatible with tight-pitch layouts requiring SMPC's 3.70 × 3.40 mm outline | Preferred when higher single-pulse energy absorption is needed and board space permits larger footprint |
Compared with SMAJ26A-E3/5A and SMCJ26A, the SMPC26AN-M3/I offers superior automotive readiness (AEC-Q101), lower profile (1.1 mm), tighter thermal resistance control (RθJA ≤ 100 °C/W), and guaranteed halogen-free/RoHS compliance-making it optimal for next-gen compact ECU and ADAS power stages.

FAQ
What is the exact breakdown voltage range for SMPC26AN-M3/I?
The SMPC26AN-M3/I has a guaranteed breakdown voltage (VBR) range of 28.9 V to 31.9 V at 1 mA test current, as specified in the Vishay document 89116. This range ensures consistent avalanche turn-on behavior across production lots and supports robust design margins for 26 V system rails.
Is SMPC26AN-M3/I qualified for automotive use?
Yes, SMPC26AN-M3/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "AN" and documentation stating AEC-Q101 qualification applies to SMPC22AN through SMPC85AN. This qualification covers temperature cycling, humidity bias, and mechanical shock testing required for automotive under-hood and cabin applications.
What does the "/I" suffix indicate in SMPC26AN-M3/I?
The "/I" suffix denotes the preferred package code for 13-inch diameter plastic tape and reel delivery, containing 6500 units per reel. It is part of Vishay's standardized ordering nomenclature and does not affect electrical or thermal specifications of the SMPC26AN-M3/I device itself.
How does the dual-anode configuration of SMPC26AN-M3/I improve performance?
The dual-anode (Anode 1 + Anode 2) structure of SMPC26AN-M3/I reduces effective series inductance and spreads surge current across two parallel paths, lowering incremental surge resistance and improving clamping consistency during fast-rising transients compared to single-anode TVS devices of similar rating.
Can SMPC26AN-M3/I be used in bidirectional configurations?
No, SMPC26AN-M3/I is strictly unidirectional, as stated in the Vishay datasheet. It conducts only when cathode is positive relative to both anodes. For bidirectional protection, a separate back-to-back configuration using two SMPC26AN-M3/I devices or a dedicated bidirectional TVS (e.g., SMPC26CA) would be required.
