Product details

Overview

AR1FJ-M3/H from Vishay General Semiconductor is a surface-mount fast avalanche rectifier in the eSMP® Series, configured as a single diode with 600 V maximum repetitive peak reverse voltage (V_RRM), 1.0 A average forward current (I_F(AV)), and 140 ns reverse recovery time (t_rr). It operates up to 175 °C junction temperature and is AEC-Q101 qualified for automotive applications including freewheeling in DC-DC converters.

For engineers reviewing the AR1FJ-M3/H datasheet, AR1FJ-M3/H pinout, AR1FJ-M3/H application, or AR1FJ-M3/H equivalent, this device delivers low-profile SOD-123W-compatible packaging, glass-passivated junction reliability, and validated avalanche energy handling (20 mJ) - critical for high-frequency power supply and inverter design where thermal robustness and fast switching are required.

Technical Context

This fast avalanche rectifier uses a glass-passivated pellet chip junction enabling stable operation under repetitive surge conditions. Its 140 ns reverse recovery time and 1.25 V forward voltage at 1.0 A (T_J = 25 °C) support high-frequency switching in flyback and boost topologies.

The SMF (DO-219AB) package provides UL 94 V-0 flammability rating and meets JESD 201 Class 2 whisker resistance. With R_θJA = 130 °C/W and R_θJM = 20 °C/W, it enables efficient thermal transfer when mounted on 2 oz. copper pads per Vishay's recommended footprint.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports input rectification in 400 V AC line-derived supplies and 300–450 V DC bus applications
I_F(AV)	1.0 A - rated continuous forward current at T_A = 25 °C with derating above 25 °C per Fig. 1
t_rr	140 ns - enables operation up to ~350 kHz switching frequency before significant switching loss dominates
V_F @ I_F = 1 A	1.25 V (25 °C), 1.15 V (125 °C) - low conduction loss improves efficiency in high-duty-cycle freewheeling paths
E_AS	20 mJ - verified non-repetitive avalanche energy at I_AS = 1.0 A, critical for inductive load snubbing without clamping
I_R	1 μA @ rated V_R, 25 °C - ensures minimal leakage in standby or high-impedance hold circuits
T_J max.	175 °C - allows operation in under-hood automotive environments and sealed industrial enclosures

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 AR1FJHM3/H	AEC-Q101 qualified; identical electrical specs; HM3 suffix denotes automotive qualification	Required for automotive production programs requiring PPAP documentation and traceable lot data	Select AR1FJHM3/H when automotive qualification and full AEC-Q101 test reports are mandatory
ON Semiconductor MUR1060CT	TO-220AC package; 10 A I_F(AV); 60 ns t_rr; higher V_F = 1.7 V @ 1 A	Used in higher-power industrial supplies where heatsinking is available and faster t_rr is prioritized over size	Choose MUR1060CT only when board space permits TO-220 and thermal design accommodates higher V_F loss

Compared with AR1FJ-M3/H, AR1FJHM3/H offers identical performance with certified automotive compliance, while MUR1060CT trades miniaturization and low-profile mounting for higher surge capacity and faster recovery - making AR1FJ-M3/H optimal for space- and weight-sensitive 1 A applications where AEC-Q101 is not mandated.

FAQ

What is the maximum junction temperature rating for AR1FJ-M3/H?

The AR1FJ-M3/H has a maximum junction temperature (T_J) of +175 °C, verified per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 125 °C. The device maintains specified electrical characteristics up to this limit when thermal design adheres to Vishay's recommended pad layout and R_θJA = 130 °C/W derating curve.

Is AR1FJ-M3/H pin-compatible with other devices in the AR1F series?

Yes, all AR1F-series devices including AR1FJ-M3/H share identical SMF (DO-219AB) package dimensions and anode/cathode terminal layout. The marking "ARJ" on the cathode end confirms polarity alignment across AR1FD, AR1FG, AR1FJ, AR1FK, and AR1FM variants. No PCB redesign is needed when substituting within the same voltage grade, provided thermal and electrical margins remain acceptable.

Does AR1FJ-M3/H meet automotive qualification standards?

AR1FJ-M3/H is halogen-free and RoHS-compliant but not AEC-Q101 qualified; that status applies only to the HM3-suffix variant (AR1FJHM3/H). While AR1FJ-M3/H shares the same die and construction, it lacks the extended stress-test documentation required for automotive PPAP submission. For production automotive use, AR1FJHM3/H must be selected instead.

What is the reverse recovery time (t_rr) specification for AR1FJ-M3/H?

The AR1FJ-M3/H has a maximum reverse recovery time (t_rr) of 140 ns, measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is confirmed across production lots and supports switching frequencies up to approximately 350 kHz in hard-switched topologies. At elevated junction temperatures, t_rr remains stable due to the optimized epitaxial structure.

Can AR1FJ-M3/H be used in reflow soldering processes?

Yes, AR1FJ-M3/H is fully compatible with standard lead-free reflow soldering profiles, including peak temperatures up to 260 °C (per J-STD-020 MSL Level 1). The matte tin-plated terminals meet J-STD-002 and JESD 22-B102 solderability requirements, and the molding compound is rated UL 94 V-0. No pre-baking is required prior to reflow.
