Diodes Incorporated SD101AW-13-F

Overview

SD101AW-13-F from Diodes Incorporated is a Schottky barrier switching diode in SOD-123 package, rated for 60 V peak repetitive reverse voltage, 15 mA forward continuous current, and 0.41 V forward voltage at 1.0 mA - optimized for low-power signal switching and ESD-sensitive signal path protection in portable electronics.

For engineers reviewing the SD101AW-13-F datasheet, SD101AW-13-F pinout, SD101AW-13-F application, or SD101AW-13-F equivalent, key selection criteria include its 1.0 ns reverse recovery time, 2.0 pF junction capacitance at 0 V, guard ring construction for transient immunity, RoHS-compliant green molding compound, and cathode-band polarity marking.

Technical Context

This discrete Schottky diode operates with negligible minority-carrier storage, enabling ultrafast switching in high-frequency signal routing. Its guard ring structure provides inherent transient voltage suppression without external components, and the SOD-123 package supports automated placement on space-constrained PCBs.

The device exhibits a soft reverse recovery characteristic (trr = 1.0 ns) under IF = IR = 5.0 mA conditions, with reverse leakage limited to 200 nA at VR = 50 V. Its low CT of 2.0 pF at 0 V and f = 1 MHz makes it suitable for RF detector and high-speed logic interface applications.

FAQ

What is the maximum operating temperature for SD101AW-13-F?

The SD101AW-13-F has an operating junction temperature range of –65 °C to +125 °C. Its thermal resistance RθJA is 300 °C/W on standard FR-4 board with recommended pad layout, meaning it remains within safe limits up to 125 °C ambient when dissipating ≤400 mW - verified per DS11012 Rev. 19-2.

Is SD101AW-13-F pin-compatible with SD101BW-13-F or SD101CW-13-F?

No - all three share identical SOD-123 packaging and pinout (anode/cathode), but differ in voltage ratings: SD101AW is 60 V VRRM, SD101BW is 50 V, and SD101CW is 40 V. Substitution requires verification of reverse voltage margin in the target circuit per datasheet Table 1.

Does SD101AW-13-F require derating above 25 °C ambient?

Yes - Figure 4 in DS11012 shows linear power derating starting at 25 °C: PD decreases from 400 mW to zero at 150 °C ambient. At 85 °C ambient, maximum allowable power dissipation is 200 mW, corresponding to ~10 mA continuous forward current under typical thermal conditions.

Can SD101AW-13-F be used as a replacement for BAT54S in dual-diode configurations?

No - SD101AW-13-F is a single anode–cathode device in SOD-123, whereas BAT54S is a dual-series Schottky in SOT-23. Though electrically similar per diode, the package and terminal count differ fundamentally; direct replacement would require PCB layout revision and separate placement of two SD101AW units.
