Product details
Overview
AR1FD-M3/I from Vishay General Semiconductor is a surface-mount fast avalanche rectifier in the eSMP® Series, configured as a single diode with 200 V maximum repetitive peak reverse voltage (VRRM), 1.0 A average forward current (IF(AV)), and 140 ns reverse recovery time (trr). It features glass passivated pellet chip junction, AEC-Q101 qualification, and is optimized for freewheeling and high-frequency rectification in automotive DC/DC converters.
For engineers reviewing the AR1FD-M3/I datasheet, AR1FD-M3/I pinout, AR1FD-M3/I application, or AR1FD-M3/I equivalent, key selection criteria include its 200 V VRRM, 1.25 V forward voltage at 1.0 A and 25 °C, 1 μA reverse leakage at rated voltage, SMF (DO-219AB) package compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device implements a fast-recovery avalanche-rated silicon PN junction in a low-profile SMF (DO-219AB) package with matte tin-plated leads. Its 140 ns trr and 1.25 V VF at IF = 1.0 A support efficient switching in 100–500 kHz power stages, while the 20 mJ non-repetitive avalanche energy rating enables robust operation under inductive load transients.
The AR1FD-M3/I operates across –55 °C to +175 °C junction temperature range and meets JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 standards. Its thermal resistance of RθJA = 130 °C/W (free air, 2 oz. pad) and RθJM = 20 °C/W supports thermally constrained PCB layouts in space-limited automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum blocking voltage before avalanche breakdown; defines usable input voltage range in buck/flyback secondary-side rectification. |
| IF(AV) | 1.0 A - Continuous DC forward current rating at 75 °C mount temperature; sets minimum heatsinking requirement for steady-state operation. |
| trr | 140 ns - Reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; determines switching loss and EMI profile in hard-switched topologies. |
| VF @ IF = 1.0 A, TJ = 25 °C | 1.25 V - Forward voltage drop defining conduction loss at nominal load; directly impacts efficiency in low-voltage output rails. |
| IR @ VR = VRRM, TJ = 25 °C | 1.0 μA - Reverse leakage current; critical for standby power budget in always-on automotive systems. |
| EAS | 20 mJ - Non-repetitive avalanche energy at IAS = 1.0 A; enables safe clamping of inductive kickback without failure in motor drive freewheeling. |
| TJ(max) | +175 °C - Maximum junction temperature; allows operation in under-hood environments without derating at full current. |
Pinout & Package
Package: SMF (DO-219AB), low-profile surface-mount case with cathode band marking; compatible with automated placement and reflow/wave soldering per J-STD-020 MSL Level 1 (260 °C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to lower-potential side of load or switch node; polarity must match schematic symbol to avoid catastrophic failure. |
| Cathode | Forward current exit / reverse blocking terminal | Marked by color band; ties to higher-potential rail in rectifier configuration; serves as clamp reference in freewheeling applications. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock per stress test requirements. |
| Glass passivated pellet chip junction | Eliminates edge leakage paths and enhances long-term reliability in humid or contaminated environments versus epoxy-passivated alternatives. |
| Fast switching (140 ns trr) | Reduces turn-off losses and associated EMI generation in high-frequency DC/DC converters operating above 200 kHz. |
| Low profile SMF (DO-219AB) package | 0.85 mm max height enables integration into ultra-thin modules such as ADAS camera power supplies and LED driver PCBs. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets EU Directive 2011/65/EU and IPC-1752A material declaration requirements for sustainable electronics manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast avalanche rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay AR1FDHM3/I | AEC-Q101 qualified; identical electrical specs but marked with HM3 suffix indicating automotive qualification traceability. | Required for OEM automotive BOMs mandating AEC-Q101 documentation; same footprint and performance as AR1FD-M3/I. | Select AR1FDHM3/I when automotive PPAP submission or qualification audit evidence is contractually required. |
| ON Semiconductor NRVBFS1200T3G | Same VRRM (200 V), IF(AV) (1.0 A), and DO-219AB package; trr = 150 ns (slower), VF = 1.3 V @ 1 A (higher). | Suitable for cost-sensitive industrial applications where 10 ns trr penalty and 50 mV higher VF are acceptable. | Choose NRVBFS1200T3G only if supply chain diversification is prioritized over minimal switching loss and EMI. |
Compared with AR1FDHM3/I, the AR1FD-M3/I offers identical performance but lacks formal AEC-Q101 certification documentation; versus NRVBFS1200T3G, it delivers tighter trr and lower VF, yielding measurable efficiency gains in high-frequency, thermally constrained designs.

FAQ
What is the maximum junction temperature rating for the AR1FD-M3/I?
The AR1FD-M3/I has a maximum junction temperature (TJ(max)) of +175 °C, verified per Vishay Document Number 87167. This rating allows the AR1FD-M3/I to operate reliably in under-hood automotive environments and high-ambient industrial settings without current derating up to 75 °C mount temperature. The device's thermal resistance values (RθJA = 130 °C/W, RθJM = 20 °C/W) support this extended temperature capability when mounted on recommended PCB land patterns.
Is the AR1FD-M3/I AEC-Q101 qualified?
No, the AR1FD-M3/I is not AEC-Q101 qualified; only the HM3-suffix variants (e.g., AR1FDHM3/I) carry formal AEC-Q101 qualification. The AR1FD-M3/I shares identical electrical and mechanical specifications with its HM3 counterpart but lacks the documented stress test reports required for automotive qualification. For applications requiring certified AEC-Q101 compliance, engineers must specify AR1FDHM3/I instead of AR1FD-M3/I.
What does the "M3" suffix mean in AR1FD-M3/I?
The "M3" suffix in AR1FD-M3/I indicates halogen-free, RoHS-compliant construction per IPC-1752A and Vishay's material categorization standard (Document 99912). It also confirms compliance with JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 moisture sensitivity. The "I" denotes 13-inch tape-and-reel packaging with 10,000 units per reel - a detail confirmed in the Ordering Information table of Vishay Document 87167 for the AR1FD-M3/I.
What is the reverse recovery time (trr) of the AR1FD-M3/I and how is it measured?
The AR1FD-M3/I has a reverse recovery time (trr) of 140 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as specified in the Electrical Characteristics table of Vishay Document 87167. This parameter reflects the time required for minority carriers to clear the depletion region during turn-off and directly influences switching loss and EMI in high-frequency power converters. The 140 ns value positions the AR1FD-M3/I between standard and ultrafast recovery diodes for balanced performance.
Can the AR1FD-M3/I replace Schottky diodes in 200 V applications?
The AR1FD-M3/I is not a direct replacement for Schottky diodes due to its higher forward voltage (1.25 V vs. typical 0.4–0.6 V for Schottkys) and slower recovery (140 ns vs. <10 ns for Schottkys), but it provides superior VRRM stability and avalanche ruggedness. In 200 V applications where thermal runaway risk exists - such as high-temperature automotive environments - the AR1FD-M3/I's silicon PN junction and 20 mJ EAS rating make it a more robust alternative than Schottky diodes, which degrade rapidly above 150 °C.
