Diodes Incorporated BAS70-05Q-13-F

Overview

BAS70-05Q-13-F from Diodes Incorporated is a 70 mA surface-mount Schottky barrier diode in SOT23 package, featuring 70 V peak reverse voltage, 0.41 V max forward voltage at 1.0 mA, and 100 nA max reverse leakage at 50 V. It integrates a PN junction guard ring for ESD and transient protection, and is AEC-Q101 qualified for automotive power rail clamping and signal-level rectification.

For engineers reviewing the BAS70-05Q-13-F datasheet, BAS70-05Q-13-F pinout, BAS70-05Q-13-F application, or BAS70-05Q-13-F equivalent, key selection criteria include low VF for efficiency-critical bias networks, fast 2.5 ns reverse recovery for high-frequency switching nodes, and guaranteed 70 V VR capability in space-constrained DC-DC feedback paths.

Technical Context

This Schottky diode uses a planar epitaxial structure with integrated PN guard ring to suppress edge breakdown and improve ESD robustness without compromising switching speed. Its low 1.7 pF capacitance at 0 V and 2.5 ns tRR enable use in RF detector and high-speed sample-and-hold circuits.

The device operates across –55°C to +125°C junction temperature range and delivers stable 0.41 V VF up to 15 mA, supporting precision voltage reference clamping and low-current logic-level translation where thermal drift must be minimized.

FAQ

What is the maximum reverse voltage rating for BAS70-05Q-13-F?

The device has a peak repetitive reverse voltage (VRRM) of 70 V, verified per DS41740 Rev. 2–2. This rating applies under standard test conditions (TA = +25°C, pulse duration <300 µs) and supports reliable operation in 48 V automotive systems with safety margin. Derating is required above +25°C per Figure 1 power curve.

Is BAS70-05Q-13-F suitable for high-frequency RF applications?

Yes-it exhibits 1.7 pF total capacitance at 0 V and 2.5 ns reverse recovery time, enabling use in RF detector and envelope demodulator circuits up to 2.4 GHz. Its low series resistance and minimal charge storage preserve signal fidelity in narrowband receivers without requiring external tuning.

Does BAS70-05Q-13-F require external ESD protection?

No. The integrated PN junction guard ring provides inherent ESD robustness per AEC-Q101 (HBM ≥2 kV), eliminating the need for discrete TVS devices in most automotive and industrial interfaces. This is confirmed in the "Features and Benefits" section of DS41740 and validated in Diodes' PPAP documentation.

How does BAS70-05Q-13-F differ from BAS70-06Q-13-F?

BAS70-05Q-13-F and BAS70-06Q-13-F share identical package, ratings, and construction, differing only in marking code and internal die variant. Both meet the same electrical specs (70 V VR, 0.41 V VF, 2.5 ns tRR); the -05Q and -06Q suffixes denote manufacturing lot traceability-not functional differentiation.
