Product details

Overview

BYG24J-M3/TR from Vishay General Semiconductor is a fast avalanche SMD rectifier diode in SMA (DO-214AC) package, rated for 600 V repetitive peak reverse voltage (V_RRM), 1.5 A average forward current (I_F(AV)), and 140 ns reverse recovery time (t_rr). It delivers soft recovery characteristics and low reverse leakage (1.0 µA at 25 °C), making it suitable for high-frequency freewheeling in automotive DC/DC converters.

For engineers reviewing the BYG24J-M3/TR datasheet, BYG24J-M3/TR pinout, BYG24J-M3/TR application, or BYG24J-M3/TR equivalent, key selection criteria include its 600 V V_RRM, 20 mJ avalanche energy rating, halogen-free RoHS-compliant construction (M3 suffix), and AEC-Q101 qualification eligibility via HM3 variant.

Technical Context

This device is a single-die, unidirectional silicon rectifier with glass-passivated junction and cathode-band polarity marking. Its fast soft-recovery behavior minimizes switching losses and EMI in hard-switched topologies, while the 150 °C maximum junction temperature supports operation in thermally constrained automotive and industrial power stages.

The SMA package provides surface-mount compatibility with J-STD-002 solderability and JESD22-B102 tin whisker resistance (Class 2). Thermal resistance is 25 °C/W junction-to-case and 125–150 °C/W junction-to-ambient depending on PCB copper area - critical for thermal design in compact SMPS layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports input rectification in 400 V AC line-derived or 300–450 V DC bus applications without derating
I_F(AV)	1.5 A at T_A = 65 °C - enables continuous conduction mode operation in sub-30 W flyback or buck-derived supplies
t_rr	140 ns - reduces turn-off switching loss and limits voltage overshoot during inductive load commutation
V_F	1.25 V at I_F = 1.5 A - contributes to <1.9 W conduction loss at full load in typical 12 V output designs
E_R	20 mJ - withstands repetitive inductive energy dump in freewheeling paths of motor drivers or solenoid controls
T_J(max)	150 °C - allows operation in under-hood automotive environments with minimal thermal margin loss
I_R	1.0 µA at V_R = 600 V, 25 °C - ensures low standby power loss in always-on systems

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L06S	600 V V_RRM, 1.0 A I_F(AV), 75 ns t_rr, TO-277 package	Lower average current rating; faster recovery but higher V_F (1.7 V)	Select when ultra-fast recovery is prioritized over conduction loss and board space permits larger TO-277 footprint
ES1J-M3/84A	600 V V_RRM, 1.0 A I_F(AV), 35 ns t_rr, SMA package	Half the average current rating; significantly faster but lower avalanche ruggedness (E_R = 5 mJ)	Choose for low-power, high-frequency flybacks where avalanche stress is absent and minimal t_rr dominates design priority

Compared with STTH1L06S and ES1J-M3/84A, BYG24J-M3/TR uniquely balances 1.5 A current capability, 140 ns soft recovery, and 20 mJ avalanche energy in the compact SMA package - making it optimal for thermally demanding, inductively stressed freewheeling roles where reliability trumps raw speed.

FAQ

What is the maximum junction temperature rating for BYG24J-M3/TR?

The BYG24J-M3/TR has a maximum junction temperature (T_J(max)) of +150 °C, verified per Vishay Document Number 88960. This rating enables reliable operation in under-hood automotive environments and enclosed industrial power supplies. Derating curves in the datasheet define safe I_F(AV) limits above 65 °C ambient, and thermal design must account for R_θJA values of 125–150 °C/W depending on PCB copper area.

Is BYG24J-M3/TR AEC-Q101 qualified?

BYG24J-M3/TR itself is not AEC-Q101 qualified; however, the HM3 variant (e.g., BYG24JHM3_A/H) is explicitly qualified per AEC-Q101. The M3 suffix indicates halogen-free RoHS compliance only. For automotive applications requiring formal qualification, engineers must specify the HM3 version - which shares identical electrical specs and SMA packaging but undergoes additional stress testing per the AEC standard.

What does the "M3" suffix mean in BYG24J-M3/TR?

The "M3" suffix in BYG24J-M3/TR denotes halogen-free, RoHS-compliant construction meeting JEDEC standards for material content and solderability. It confirms compliance with IPC/JEDEC J-STD-020 (MSL Level 1, 260 °C peak reflow), JESD22-B102 (tin whisker resistance Class 2), and Vishay's internal halogen-free policy. It does not imply AEC-Q101 qualification - that requires the "HM3" suffix.

How does BYG24J-M3/TR compare to BYG24D-M3/TR and BYG24G-M3/TR?

BYG24J-M3/TR differs from BYG24D-M3/TR and BYG24G-M3/TR solely in V_RRM: 600 V (J), 200 V (D), and 400 V (G). All share identical I_F(AV) = 1.5 A, t_rr = 140 ns, V_F = 1.25 V, and SMA packaging. Selection depends strictly on system-level voltage stress requirements - BYG24J-M3/TR is mandatory for 400 V DC bus or 230 V AC line-derived designs where 600 V blocking is needed.

What is the reverse recovery time (t_rr) test condition for BYG24J-M3/TR?

The reverse recovery time (t_rr) of 140 ns for BYG24J-M3/TR is measured under the conditions specified in Vishay Document 88960: I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A, with diode junction temperature at 25 °C. This standardized test reflects real-world switching behavior in freewheeling and snubber applications, and the soft recovery waveform minimizes associated voltage overshoot and EMI.
