Nexperia USA Inc. BAS316,135

Overview

BAS316 from Nexperia is a high-speed switching diode in SOD323 (SC-76) package, designed for fast signal routing and low-loss rectification in compact PCB layouts. It delivers trr ≤ 4 ns reverse recovery time, VR ≤ 100 V peak reverse voltage, and IF = 250 mA continuous forward current, with VF = 855 mV at 10 mA - enabling efficient operation in digital logic interface and pulse shaping circuits.

For engineers reviewing the BAS316 datasheet, BAS316 pinout, BAS316 application, or BAS316 equivalent, key selection criteria include verified trr performance under IF = 10 mA/IR = 10 mA test conditions, low 1.5 pF junction capacitance at 0 V, and thermal resistance Rth(j-sp) = 150 K/W - critical for high-frequency switching stability in space-constrained designs.

Technical Context

The BAS316 employs a planar epitaxial silicon structure optimized for minimal minority-carrier storage, directly enabling its ≤ 4 ns trr. Its low leakage (IR ≤ 0.5 µA at VR = 80 V, Tj = 25 °C) and stable VF across temperature support reliable level-shifting in mixed-signal systems.

Designed for surface-mount use on FR4 PCBs with single-side copper, it operates across -65 °C to +150 °C ambient range and sustains 4 A non-repetitive forward surge (tp = 1 µs), making it suitable for transient-tolerant input protection and clamping functions.

FAQ

What is the maximum continuous forward current rating for BAS316?

The BAS316 is rated for 250 mA continuous forward current (IF) at Tamb = 25 °C when mounted on an FR4 PCB with single-side copper and standard footprint. Derating applies above 25 °C ambient, reaching zero at 150 °C junction temperature per the thermal resistance of 150 K/W.

Does BAS316 support reflow soldering, and what is the recommended profile?

Yes, BAS316 is qualified for lead-free reflow soldering. Nexperia specifies a peak temperature of 260 °C for ≤ 30 seconds, with ramp-up rate ≤ 3 °C/s and ramp-down rate ≤ 6 °C/s. The recommended footprint uses 0.5 mm × 1.5 mm solder lands with 0.6 mm solder resist opening per pad, as defined in Figure 8 of the datasheet.

How does BAS316 perform at elevated temperatures, particularly for reverse leakage?

At VR = 80 V and Tj = 150 °C, the BAS316 exhibits IR ≤ 50 µA - a 100× increase over its 0.5 µA rating at 25 °C. This predictable exponential rise is documented in Figure 3 of the datasheet and must be accounted for in high-temperature bias networks where leakage could affect reference stability.

Is BAS316 automotive-qualified?

No, BAS316 is not automotive-qualified. Per Nexperia's revision history (Table 8), this part was explicitly changed to non-automotive qualification in the July 2022 revision. For automotive applications, Nexperia offers the -Q qualified variants such as BAS316-Q, which undergo AEC-Q101 stress testing and include extended temperature and reliability validation.
