Nexperia USA Inc. BAS16H,115

Overview

BAS16H from Nexperia is a high-speed switching diode in SOD123F package, rated for 100 V repetitive peak reverse voltage (VRRM), 4 ns reverse recovery time (trr), and 215 mA continuous forward current (IF). It delivers low leakage (0.5 µA at VR = 80 V), low capacitance (1.5 pF), and fast transition between conduction and blocking states-ideal for signal routing and clamping in digital logic interfaces.

For engineers reviewing the BAS16H datasheet, BAS16H pinout, BAS16H application, or BAS16H equivalent, this page provides verified electrical parameters, thermal resistance values (Rth(j-a) = 330 K/W), cathode/anode terminal mapping, and real-world switching use cases-not generic diode descriptions.

Technical Context

The BAS16H operates as a single-element silicon planar epitaxial switching diode with optimized carrier lifetime control to achieve trr ≤ 4 ns under IF = 10 mA / IR = 10 mA test conditions. Its junction-to-ambient thermal resistance of 330 K/W reflects performance on standard FR4 PCBs with minimal copper area.

Designed for discrete signal-level switching-not power rectification-it exhibits VF = 855 mV at IF = 10 mA and Cd = 1.5 pF at VR = 0 V / f = 1 MHz, enabling clean edge handling in 50–100 MHz digital signal paths without capacitive loading distortion.

FAQ

What is the maximum continuous forward current rating for BAS16H?

The BAS16H is rated for 215 mA continuous forward current (IF) at Tamb ≤ 25 °C on an FR4 PCB with 60 µm copper strip line. Derating applies above 25 °C ambient: at 70 °C, maximum IF drops to approximately 130 mA based on thermal resistance (Rth(j-a) = 330 K/W) and junction temperature limit of 150 °C.

Can BAS16H be used as a replacement for 1N4148 in high-frequency applications?

Yes-BAS16H offers trr = 4 ns versus 1N4148's typical 4–8 ns, lower capacitance (1.5 pF vs. ~2–4 pF), and tighter VF consistency. Its SOD123F package is smaller than DO-35 but electrically superior for >50 MHz signal paths; however, PCB footprint compatibility must be verified prior to drop-in substitution.

What does the "A1" marking on the BAS16H package indicate?

The "A1" marking is Nexperia's standardized code for the BAS16H device in SOD123F package, per Table 4 of the datasheet. It appears adjacent to the cathode bar and serves as both type identification and traceability marker-distinct from date codes or lot identifiers.

Is BAS16H qualified for automotive applications?

No-per Section 14 revision history and Legal Information section, BAS16H is explicitly designated as non-automotive qualified. Nexperia offers automotive-grade alternatives (e.g., BAS16-Q series) with AEC-Q101 qualification, extended temperature range, and enhanced reliability testing not present in this variant.
