Diodes Incorporated RS1JB-13-F

Overview

RS1JB-13-F from Diodes Incorporated is a surface-mount fast recovery rectifier diode in SMB package, rated for 600 V peak repetitive reverse voltage, 1.0 A average rectified output current, and 150 ns maximum reverse recovery time; it delivers high-efficiency AC/DC conversion in compact power supplies and LED drivers.

For engineers reviewing the RS1JB-13-F datasheet, RS1JB-13-F pinout, RS1JB-13-F application, or RS1JB-13-F equivalent, key selection criteria include its 600 V blocking capability, low 1.3 V forward voltage at 1.0 A, 30 A non-repetitive surge rating, RoHS-compliant lead-free finish, and SMB thermal resistance of 20 °C/W - all critical for reliable operation in space-constrained industrial and consumer power circuits.

Technical Context

This device operates as a unidirectional silicon PN junction rectifier optimized for fast switching in single-phase bridge or half-wave configurations. Its glass-passivated die construction ensures stable reverse leakage (≤5.0 µA at 25°C) and robust surge tolerance (30 A, 8.3 ms half-sine).

The 150 ns reverse recovery time enables efficient operation at frequencies up to several hundred kHz, while its 15 pF typical junction capacitance minimizes high-frequency switching losses in flyback and buck-derived topologies.

FAQ

What is the cathode marking convention for RS1JB-13-F?

The cathode is marked by a distinct band on the body end of the SMB package. This band aligns with the cathode terminal in the standardized DO-214AA outline and must be oriented toward the positive output node in rectifier configurations. Polarity verification is confirmed by diode test mode on a multimeter showing conduction only when red probe contacts anode and black probe contacts cathode.

Can RS1JB-13-F replace a standard 1N4007 in a 60 Hz transformer-based supply?

Yes, RS1JB-13-F can replace 1N4007 in low-frequency linear supplies due to its higher 600 V VRRM (vs. 1N4007's 1000 V) and superior surge rating (30 A vs. 30 A), but its fast recovery offers no benefit at 60 Hz. However, its 1.3 V VFM increases conduction loss versus 1N4007's ~1.1 V, so thermal design must account for ~0.2 W extra dissipation at 1.0 A.

Is RS1JB-13-F suitable for use in a PFC boost diode position?

No - RS1JB-13-F is not rated for continuous high-frequency, high-dv/dt operation required in active PFC boost stages. Its 150 ns tRR and 15 pF CT are insufficient for >50 kHz PFC operation where ultrafast or SiC diodes with <50 ns tRR and <10 pF CT are specified. It is intended for output rectification, not boost switching.

Does RS1JB-13-F require derating when mounted on a 1 oz copper PCB without thermal vias?

Yes - with no thermal vias, the effective RθJA exceeds 60 °C/W. At 1.0 A and 1.3 V VFM (1.3 W dissipation), junction temperature rise could exceed 78 °C above ambient, risking violation of the +150 °C max TJ. Derate IO to ≤0.7 A for reliable operation at +70 °C ambient unless additional copper area or thermal vias are added.
