Nexperia USA Inc. BAS716,115

Overview

BAS716,115 from Nexperia is an epitaxial medium-speed switching diode in SOD523 (SC-79) package, featuring 0.2 nA typical reverse leakage at 75 V, 0.6 µs typical reverse recovery time, and AEC-Q101 qualification for automotive signal conditioning and biasing circuits.

For engineers reviewing the BAS716,115 datasheet, BAS716,115 pinout, BAS716,115 application, or BAS716,115 equivalent, this low-leakage diode is selected for precision voltage reference clamping, sensor interface protection, and low-current analog signal routing where thermal stability and minimal parasitic current are critical.

Technical Context

The BAS716 operates as a unidirectional silicon switching diode with optimized epitaxial structure to minimize minority-carrier storage, enabling fast turn-off (trr = 0.6 µs typ.) while maintaining ultra-low IR (0.2 nA typ. at VR = 75 V, Tj = 25 °C). Its junction temperature rating extends to 150 °C, supporting operation in thermally constrained automotive ECUs and industrial sensors.

Designed for surface-mount reliability, it uses a planar die in SC-79 package with defined cathode/anode polarity and solder-point thermal resistance of 120 K/W - critical for pulsed-current handling up to 4 A (tp = 1 µs) without thermal runaway in compact PCB layouts.

FAQ

What is the maximum continuous forward current for BAS716,115 at 100 °C ambient?

At Tamb = 100 °C, the maximum permissible continuous forward current is approximately 100 mA, derived from Fig. 1 in the datasheet showing linear derating from 200 mA at 25 °C to 0 mA at ~160 °C on FR4 PCB. This reflects thermal limits imposed by 250 mW total power dissipation and 450 K/W junction-to-ambient resistance.

Is BAS716,115 suitable for reverse-biased capacitance-sensitive applications like RF tuning?

No - its diode capacitance is 2 pF typical at VR = 0 V and 1 MHz, but it is not characterized or optimized for voltage-variable capacitance (varactor) behavior. The device lacks C-V linearity or Q-factor specification, and its epitaxial structure prioritizes low leakage over tunable junction capacitance.

Does the S1 marking on BAS716,115 indicate polarity or date code?

The "S1" marking is the device-specific identification code per Table 4, denoting BAS716 in SOD523 package; it does not encode date or lot information. Polarity is indicated physically by the cathode band adjacent to pin 1, consistent with SC-79 outline drawing in Fig. 7.

Can BAS716,115 replace BAT54 series diodes in existing designs?

Only with design validation: BAS716,115 has lower leakage (0.2 nA vs. ≥1 µA) and higher VRRM (85 V vs. 30 V), but shares no pin compatibility with BAT54's SOT-23 package. Direct replacement requires PCB redesign to SOD523 footprint and verification of reduced VF impact on forward-biased logic thresholds.
