Product details

Overview

RS2J-E3/52T from Vishay General Semiconductor is a surface-mount fast switching rectifier diode in SMB (DO-214AA) package, rated for 600 V repetitive peak reverse voltage (V_RRM), 1.5 A average forward current (I_F(AV)), and 150 ns reverse recovery time (t_rr). It serves as a freewheeling or output rectifier in DC/DC converters and offline power supplies for industrial and automotive systems.

For engineers reviewing the RS2J-E3/52T datasheet, RS2J-E3/52T pinout, RS2J-E3/52T application, or RS2J-E3/52T equivalent, key selection criteria include its 600 V blocking capability, low 1.3 V forward voltage at 1.5 A, AEC-Q101 qualification eligibility (via HE3 suffix), SMB footprint compatibility, and 50 A surge rating for transient robustness.

Technical Context

This device is a single silicon PN junction diode with glass-passivated chip construction, optimized for fast recovery (t_rr = 150 ns) to minimize switching losses in high-frequency rectification. Its thermal resistance R_θJA is 55 °C/W (on 7 mm × 7 mm copper pad), supporting operation up to 150 °C junction temperature.

The RS2J-E3/52T features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, meets MSL level 1 per J-STD-020, and carries a cathode band marking. It is RoHS-compliant (E3 suffix) and available in 7" tape-and-reel (52T code, 750 units).

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports input rectification in universal-input 230 VAC SMPS and 400 VDC bus applications
I_F(AV)	1.5 A at T_L = 100 °C - enables continuous conduction mode operation in mid-power adapters and auxiliary supplies
t_rr	150 ns - reduces switching loss and EMI in 100–500 kHz DC/DC topologies
V_F	1.3 V at I_F = 1.5 A - lowers conduction loss versus standard recovery diodes, improving efficiency by ~0.5–1.2% in 12–24 V outputs
I_FSM	50 A (8.3 ms half-sine) - withstands inrush and short-circuit transients without failure
T_J max.	150 °C - allows use in thermally constrained enclosures without derating below full load
C_J	17 pF at 4.0 V, 1 MHz - limits capacitive coupling noise in high-dv/dt gate-drive or snubber circuits

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L06U	600 V V_RRM, 1 A I_F(AV), 75 ns t_rr, TO-277 package	Lower current rating; faster recovery but higher V_F (1.7 V)	Select when ultra-fast recovery dominates over conduction loss and PCB space permits larger TO-277 footprint
ON Semi MUR160	600 V V_RRM, 1 A I_F(AV), 60 ns t_rr, DO-41 through-hole	Through-hole mounting; not SMT-compatible; higher thermal resistance	Choose only for legacy through-hole designs where rework to SMT is impractical

Compared with STTH1L06U and MUR160, the RS2J-E3/52T delivers optimal balance of 1.5 A current handling, 150 ns speed, and SMB footprint-making it preferred for new SMT designs requiring ≥1 A output rectification without sacrificing board area or thermal performance.

FAQ

What is the maximum junction temperature rating for RS2J-E3/52T?

The RS2J-E3/52T has a maximum junction temperature (T_J) of +150 °C, verified per Vishay Document Number 88708. This rating allows sustained operation in thermally demanding environments such as enclosed power supplies or under-hood automotive locations when mounted on appropriate copper area. Derating curves confirm 1.5 A I_F(AV) is maintained up to T_L = 100 °C.

Is RS2J-E3/52T RoHS-compliant and lead-free?

Yes, RS2J-E3/52T is RoHS-compliant and lead-free. The "E3" suffix explicitly denotes Vishay's RoHS-compliant commercial-grade product line, with matte tin-plated leads meeting J-STD-002 solderability requirements and JESD 22-B102 whisker testing Class 2. No lead or hazardous substances exceed EU RoHS Directive limits.

Does RS2J-E3/52T have AEC-Q101 qualification?

The RS2J-E3/52T itself is not AEC-Q101 qualified; however, the automotive-grade variant RS2JHE3_A/H is fully AEC-Q101 qualified. Per Vishay documentation, HE3-suffix parts undergo stress testing per AEC-Q101, including HTGB, HTRB, and temperature cycling. For automotive designs, specify RS2JHE3_A/H instead of RS2J-E3/52T.

What is the reverse recovery time (t_rr) of RS2J-E3/52T and how is it measured?

The RS2J-E3/52T has a typical reverse recovery time (t_rr) of 150 ns, measured under conditions I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, per Vishay Document Number 88708. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss and EMI in high-frequency converters.

What is the package type and dimensions of RS2J-E3/52T?

RS2J-E3/52T uses the SMB (DO-214AA) surface-mount package, with outline dimensions of 4.57 mm × 3.94 mm × 2.44 mm (length × width × height). The cathode is marked by a visible band; terminals are matte tin-plated for reliable solder joint formation. Mounting pad layout recommendations are provided in the Vishay datasheet for optimal thermal and mechanical performance.
