Diodes Incorporated S2JA-13-F

Overview

S2JA-13-F from Diodes Incorporated is a surface-mount glass passivated silicon rectifier diode rated for 600 V peak repetitive reverse voltage, 1.5 A average forward current at 100°C terminal temperature, and 50 A non-repetitive surge current (8.3 ms half-sine). It features low 1.15 V forward voltage drop at 1.5 A and 5.0 µA peak reverse current at 25°C, used in AC/DC input stage rectification for industrial power supplies and LED drivers.

For engineers reviewing the S2JA-13-F datasheet, S2JA-13-F pinout, S2JA-13-F application, or S2JA-13-F equivalent, key selection criteria include its 600 V VRRM rating, SMA package thermal resistance of 20 °C/W, 1.15 V VF at rated current, 20 pF junction capacitance at 4 V reverse bias, and RoHS-compliant matte tin plating.

Technical Context

This device operates as a single-phase, half-wave rectifier under resistive or inductive loads at 60 Hz. Its glass passivated die construction ensures stable reverse leakage performance up to 125°C, where IR increases to 125 µA at rated DC blocking voltage.

The SMA package enables automated placement and reflow soldering, with thermal derating defined by Fig. 1: I(AV) drops linearly from 1.5 A at 100°C TT to zero at 150°C. Capacitance is measured at 1.0 MHz with 4.0 V DC reverse bias, confirming suitability for moderate-frequency switching inputs.

FAQ

What is the maximum allowable junction temperature for S2JA-13-F?

The absolute maximum junction temperature is +150°C, but operation is specified up to +125°C for reverse leakage characterization. Derating curves assume terminal temperature (TT) ≤ 100°C for full 1.5 A average current; exceeding this requires thermal modeling using RθJT = 20 °C/W and actual power dissipation.

Is S2JA-13-F suitable for use in a full-wave bridge configuration?

Yes-S2JA-13-F is commonly used as one quadrant in discrete full-wave bridge rectifiers. Its 600 V VRRM and 50 A surge rating support standard 230 VAC bridge topologies; four devices with matched VF and IR ensure balanced current sharing and thermal distribution.

Does S2JA-13-F require snubber circuits in typical 60 Hz rectifier applications?

No snubber is required for standard resistive or inductive loads at 60 Hz. However, snubbers may be needed with highly capacitive loads or in high-dI/dt switching environments to suppress voltage overshoot caused by stray inductance interacting with CT = 20 pF.

How does the green molding compound affect soldering reliability?

The halogen- and antimony-free green compound meets IEC 61249-2-21 and shows no adverse effect on solder joint integrity or intermetallic growth during lead-free reflow. Its thermal expansion coefficient matches standard FR-4 PCBs, minimizing stress-induced cracking during thermal cycling.
