Diodes Incorporated BAS116UDJ-7

Overview

BAS116UDJ-7 from Diodes Incorporated is a dual ultra-small surface-mount switching diode in SOT963 package, featuring 85V peak reverse voltage, 215mA forward current rating, and ultra-low leakage current of 5nA at 75V reverse bias. It serves as a high-speed signal routing or polarity protection element in space-constrained portable electronics such as wearables and Bluetooth earbuds.

For engineers reviewing the BAS116UDJ-7 datasheet, BAS116UDJ-7 pinout, BAS116UDJ-7 application, or BAS116UDJ-7 equivalent, key selection criteria include its 0.12µs typical reverse recovery time, 2pF junction capacitance at 0V, dual-common-cathode configuration, and suitability for low-power RF switching and battery-isolation circuits.

Technical Context

The BAS116UDJ-7 integrates two independent silicon switching diodes in a single ultra-compact SOT963 package with shared cathode terminals (K1, K2) and isolated anodes (A1, A2). Its design targets minimal parasitic capacitance and fast transient response in bidirectional signal path control.

It operates across –55°C to +150°C ambient temperature, with thermal resistance of 500°C/W (junction-to-ambient), and supports repetitive surge currents up to 500mA. The device is characterized under standardized test conditions including IF = 10mA/IR = 10mA for trr and VR = 75V for leakage.

Key Specifications

Pinout & Package

FAQ

What is the pin configuration of BAS116UDJ-7?

The BAS116UDJ-7 uses a 6-pin SOT963 package with pins A1, K1, NC, A2, K2, NC in top-view order. A1 and A2 are independent anodes; K1 and K2 are internally shorted cathodes; two pins are unconnected. This matches the dual-common-cathode schematic shown in DS35244 Rev. 4–3, page 2.

Is BAS116UDJ-7 RoHS and halogen-free compliant?

Yes. The device is fully compliant with EU RoHS Directive 2011/65/EU and classified as "Green" per Diodes Inc.'s policy: <900 ppm bromine, <900 ppm chlorine, <1000 ppm antimony, and UL 94V-0 flammability rating. Compliance is confirmed in DS35244 Notes 1–3.

Can BAS116UDJ-7 replace BAS16 or BAV99 in existing designs?

No direct replacement: BAS116UDJ-7 has different pinout (SOT963 vs. SOT-23/SC-70), lower IFM (215mA vs. 200–300mA), and tighter leakage (5nA vs. 100nA). Its ultra-low capacitance and dual-common-cathode structure suit new miniaturized layouts but require PCB redesign for legacy footprints.

What is the maximum operating temperature for continuous use?

The device is rated for continuous operation from –55°C to +150°C junction temperature. At 25°C ambient, maximum continuous power dissipation is 250 mW; derating follows the curve in Figure 1 of DS35244, reaching zero dissipation at 150°C ambient due to RθJA = 500°C/W.
