Diodes Incorporated RS3BB-13

Overview

RS3BB-13 from Diodes Incorporated is a 100V peak repetitive reverse voltage, 3.0A average forward current, fast recovery surface-mount rectifier in SMB package with 150 ns maximum reverse recovery time, 1.3 V forward voltage at 3.0 A, and glass-passivated die construction-used in AC/DC front-end rectification for industrial power supplies and LED drivers.

For engineers reviewing the RS3BB-13 datasheet, RS3BB-13 pinout, RS3BB-13 application, or RS3BB-13 equivalent, key selection criteria include VRRM rating, trr performance under 60 Hz half-wave resistive load, thermal resistance (25 K/W), and SMB footprint compatibility with automated SMT assembly.

Technical Context

This device operates as a single-phase, half-wave silicon rectifier optimized for high-efficiency switching power conversion. Its fast recovery (trr ≤ 150 ns) minimizes switching losses in flyback and boost PFC stages, while the glass-passivated junction ensures stable operation across -65°C to +150°C junction temperature range.

The SMB package enables compact layout with 0.09 g mass and UL 94V-0 flammability compliance. Terminal design meets MIL-STD-202 Method 208 solderability requirements, supporting reflow and wave soldering without degradation of the 100 A non-repetitive surge rating (8.3 ms half-sine).

FAQ

What is the maximum junction temperature for RS3BB-13?

The absolute maximum junction temperature is +150°C, and the storage temperature range matches this. Operation above this limit risks permanent parametric shift or catastrophic failure. Derating curves in the datasheet show that at 75°C terminal temperature, the device sustains 3.0 A average forward current-exceeding this requires thermal modeling or forced cooling.

Can RS3BB-13 be used in full-wave bridge configurations?

Yes-RS3BB-13 is rated for single-phase, half-wave operation per JEDEC test conditions, but its 100 V VRRM and 100 A IFSM make it suitable for use in discrete full-wave bridges. In such layouts, each diode sees only half the peak inverse voltage of the AC input, so a 100 V part supports up to ~140 VAC RMS inputs.

Is RS3BB-13 compliant with lead-free soldering processes?

Yes-the SMB package terminals are solder-plated and qualified per MIL-STD-202, Method 208, supporting both lead-free (SnAgCu, 260°C peak) and tin-lead reflow profiles. The plastic body remains stable up to 260°C for 60 seconds, meeting IPC/JEDEC J-STD-020 moisture sensitivity level 1.

How does the 150 ns recovery time impact EMI in a 65 kHz flyback converter?

In a 65 kHz flyback, the 150 ns trr causes minimal reverse recovery charge (Qrr ≈ 35 nC, derived from trr × di/dt), resulting in low high-frequency ringing amplitude (<100 MHz). This reduces conducted EMI burden on input filters compared to standard recovery diodes (trr > 1 µs), easing EMC certification for Class B equipment.
