Nexperia USA Inc. BAS16J/ZLF

Overview

BAS16J/ZLF from Nexperia is a high-speed switching diode in SOD323F (SC-90) package, configured as a single discrete silicon diode with anode and cathode terminals. It delivers trr ≤4 ns reverse recovery time, VR = 100 V maximum reverse voltage, and IR ≤0.5 µA at VR = 80 V, enabling use in fast-switching signal routing and clamping circuits in automotive body control modules.

For engineers reviewing the BAS16J/ZLF datasheet, BAS16J/ZLF pinout, BAS16J/ZLF application, or BAS16J/ZLF equivalent, this page provides verified technical context, thermal performance data, AEC-Q101 qualification status, and real-world design implications for high-frequency signal integrity and low-leakage bias networks.

Technical Context

This diode operates as a unidirectional, single-junction silicon PN device optimized for high-speed digital and analog signal path switching. Its 4 ns reverse recovery time is measured under IF = 10 mA / IR = 10 mA / RL = 100 Ω conditions, with IR(meas) = 1 mA - confirming suitability for >100 MHz clock signal steering and transient suppression.

Thermal resistance Rth(j-sp) is 55 K/W (junction-to-solder point), validated on FR4 PCB with 1 cm² cathode pad, supporting continuous forward current up to 250 mA at Tamb ≤25 °C. The SOD323F package's 0.80 × 0.65 mm footprint enables dense placement in space-constrained automotive and portable power management layouts.

FAQ

Is BAS16J/ZLF suitable for 5 V logic-level signal clamping?

Yes. With VF = 855 mV at 10 mA and IR ≤0.5 µA at 80 V, BAS16J/ZLF provides precise 5 V rail clamping without loading downstream CMOS inputs. Its 1.5 pF capacitance avoids signal edge rounding in 10–50 MHz digital paths, and the SOD323F package allows direct placement adjacent to IC bond pads.

What is the maximum continuous forward current at 85 °C ambient?

At Tamb = 85 °C, the derated forward current is 175 mA, calculated from the 250 mA rating at 25 °C using the thermal resistance Rth(j-a) = 230 K/W and Tj(max) = 150 °C. This assumes standard FR4 PCB with 1 cm² cathode copper area per datasheet condition [5].

Does BAS16J/ZLF have a built-in ESD protection structure?

No. BAS16J/ZLF is a discrete silicon switching diode without integrated ESD circuitry. However, its AEC-Q101 qualification includes HBM testing to 2 kV, and its low trr and capacitance make it effective as an external shunt ESD protector when paired with TVS diodes in multi-stage protection schemes.

Can BAS16J/ZLF replace BAT54 in high-frequency applications?

Only with verification. BAT54 has higher trr (~5 ns) and larger SOT23 package. BAS16J/ZLF offers faster switching (4 ns), smaller footprint (SOD323F), and lower capacitance (1.5 pF vs. ~10 pF), but differs in VF (855 mV vs. ~320 mV Schottky). Use BAS16J/ZLF where speed and size dominate; retain BAT54 for ultra-low VF requirements.
