Product details
Overview
V8PA22HM3/I from Vishay General Semiconductor is a surface-mount Trench MOS Barrier Schottky (TMBS®) rectifier in SMPA (DO-221BC) package, rated for 200 V repetitive peak reverse voltage, 8.0 A average forward current, and 100 A non-repetitive surge current, with low 0.70 V forward voltage at 8.0 A and 125 °C junction temperature-used for polarity protection and freewheeling in automotive DC/DC converters.
For engineers reviewing the V8PA22HM3/I datasheet, V8PA22HM3/I pinout, V8PA22HM3/I application, or V8PA22HM3/I equivalent, key selection criteria include its AEC-Q101 qualification (HM3 suffix), ultra-low profile (0.95 mm height), MSL Level 1 rating, 175 °C max junction temperature, and thermal resistance of 100 °C/W (junction-to-ambient on 3 cm × 3 cm copper pad).
Technical Context
This TMBS® rectifier uses trench MOS Schottky technology to achieve lower forward voltage and reduced power losses versus planar Schottky diodes. Its single-anode/cathode configuration supports unidirectional conduction in high-frequency switching topologies.
Designed for operation up to 175 °C junction temperature, it delivers stable performance under automotive thermal cycling stress. The SMPA (DO-221BC) package enables compact PCB layout while meeting JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - blocks up to 200 V reverse voltage without breakdown in DC/DC converter input stages |
| IF(AV) | 8.0 A - continuous forward current capability on 3 cm × 3 cm copper pad at TA = 25 °C |
| VF @ 8.0 A, 125 °C | 0.70 V - enables high-efficiency operation in thermally stressed automotive environments |
| IFSM | 100 A - withstands short-duration inrush or fault currents in freewheeling paths |
| TJ max. | 175 °C - supports under-hood automotive applications without derating at elevated ambient |
| RθJA | 100 °C/W - defines thermal design margin when mounted on standard FR4 PCB with 3 cm² copper area |
| CJ @ 4 V, 1 MHz | 400 pF - limits high-frequency switching noise and EMI in >100 kHz DC/DC topologies |
Pinout & Package
Package: SMPA (DO-221BC), ultra-low-profile surface-mount case with matte tin-plated terminals, cathode identified by color band. Dimensions: 4.35 mm × 2.70 mm × 0.95 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Current entry terminal | Connected to source-side of switching node; requires low-inductance trace routing for high-frequency freewheeling |
| Cathode (K) | Current exit terminal | Connected to return path or output rail; thermal pad contact critical for RθJM = 5 °C/W mounting on aluminum PCB |
Key Features
| Feature | Design Value |
|---|---|
| Trench MOS Schottky technology | Reduces VF by ~15–20% vs. planar Schottky at 8 A, lowering conduction loss in 12 V–48 V automotive DC/DC stages |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per AEC specification |
| MSL Level 1, 260 °C peak reflow | Enables standard SMT assembly without moisture sensitivity handling or baking prior to reflow |
| UL 94 V-0 molding compound | Meets flame-retardancy requirements for under-hood and infotainment module enclosures |
| Junction-to-mount thermal resistance (RθJM) | 5 °C/W - enables direct thermal coupling to metal-core PCBs for high-power density designs |
Applications
| Automotive DC/DC Converters | Industrial Freewheeling Diodes |
|---|---|
Use Scenario: Step-down conversion from 48 V battery to 12 V subsystem rail in mild-hybrid vehicles. IC Role / Device Role / Timing Role: Output rectifier in synchronous buck topology, conducting during low-side FET off-time. Use Value: 0.70 V VF at 125 °C reduces conduction loss by ~0.56 W vs. legacy Schottky, improving efficiency at full load. |
Use Scenario: Flyback energy recovery in industrial motor drive snubber circuits. IC Role / Device Role / Timing Role: Unidirectional clamp path for inductive kickback suppression during IGBT turn-off. Use Value: 100 A IFSM rating handles transient surges without degradation; 175 °C TJ max ensures stability during intermittent overload. |
| Commercial Polarity Protection | High-Frequency Inverters |

IC Role / Device Role / Timing Role: Series-connected anode-in configuration preventing damage from miswired power inputs. Use Value: 200 V VRRM exceeds IEEE 802.3af/bt surge requirements; 0.001 mA IR at 160 V minimizes standby leakage. |
Use Scenario: Output stage rectification in 200–500 kHz solar microinverters. IC Role / Device Role / Timing Role: High-speed unidirectional conduction path replacing fast recovery diodes. Use Value: 400 pF CJ and low VF enable <10 ns reverse recovery, reducing switching loss and EMI generation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| V8PA22-M3/I | No AEC-Q101 qualification; same electrical specs and SMPA package | Suitable for commercial-grade power supplies where automotive qualification is not required | Select V8PA22HM3/I when AEC-Q101 compliance and extended temperature validation are mandatory |
| SS8P2L-M3/84A | Lower 20 V VRRM, 8 A IF(AV), same DO-221BC package but no AEC-Q101 or MSL Level 1 rating | Limited to low-voltage consumer electronics; not suitable for 48 V automotive systems | Choose V8PA22HM3/I for 200 V blocking and under-hood thermal robustness |
Compared with V8PA22-M3/I and SS8P2L-M3/84A, the V8PA22HM3/I uniquely combines 200 V rating, AEC-Q101 qualification, and 175 °C operation-making it the only option validated for front-end rectification in ISO 26262-compliant 48 V vehicle architectures.

FAQ
What does the 'HM3' suffix indicate in V8PA22HM3/I?
The 'HM3' suffix in V8PA22HM3/I denotes halogen-free, RoHS-compliant construction with full AEC-Q101 qualification for automotive applications. It distinguishes this variant from the commercial-grade V8PA22-M3/I, which shares identical electrical parameters but lacks automotive reliability validation and extended temperature testing.
Is V8PA22HM3/I compatible with lead-free reflow processes?
Yes, V8PA22HM3/I meets J-STD-020 MSL Level 1 and supports peak reflow temperatures up to 260 °C, making it fully compatible with standard lead-free soldering profiles. Its matte tin-plated terminals comply with J-STD-002 and JESD22-B102 for reliable wetting and intermetallic formation.
How does the thermal performance of V8PA22HM3/I compare between FR4 and aluminum PCB mounting?
V8PA22HM3/I achieves RθJA = 100 °C/W on 3 cm × 3 cm FR4 copper, but when mounted on aluminum PCB per recommended footprint, its RθJM drops to 5 °C/W-enabling 20× better heat transfer. This allows sustained 8 A operation at higher ambient temperatures in chassis-mounted automotive modules.
Can V8PA22HM3/I replace standard Schottky diodes in existing 200 V designs?
V8PA22HM3/I can directly replace legacy 200 V Schottky diodes in the same SMPA (DO-221BC) footprint, provided the design accommodates its lower VF and higher TJ rating. Its 0.70 V VF at 8 A and 125 °C improves efficiency over typical planar Schottky devices rated at 0.85–0.95 V under same conditions.
What is the significance of the 'I' in the ordering code V8PA22HM3/I?
The 'I' in V8PA22HM3/I specifies packaging in 13-inch diameter plastic tape and reel with 14,000 units per reel-optimized for high-volume SMT production lines. This contrasts with the 'H' variant (V8PA22HM3/H), which uses 7-inch reels holding 3,500 units and suits low-to-medium volume builds or prototyping.
