Diodes Incorporated BAS7005TC

Overview

BAS7005TC from Nexperia is a dual Schottky barrier diode in SOT23 package with common cathode configuration, 70 V reverse breakdown voltage, 410 mV forward voltage at 1 mA, and 2.0 pF junction capacitance at 1 MHz - used in high-speed signal clamping and RF detector circuits.

For engineers reviewing the BAS7005TC datasheet, BAS7005TC pinout, BAS7005TC application, or BAS7005TC equivalent, key selection criteria include low VF for minimal conduction loss, sub-200 nA IR at 50 V for low standby leakage, and <100 ps minority carrier lifetime for GHz-range switching fidelity.

Technical Context

This dual Schottky diode integrates two identical anode-cathode junctions sharing a common cathode terminal (Pin 3), enabling balanced clamping or dual-path detection without external node tying. Its planar silicon construction ensures stable τ ≤ 100 ps and CT = 2.0 pF under zero bias.

The device operates across –55 °C to +150 °C with Ptot = 330 mW at 25 °C ambient, and achieves IF = 15 mA maximum continuous forward current while maintaining VF ≤ 410 mV at IF = 1 mA - critical for low-power envelope detection in portable RF receivers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Schottky diode applications.

Compared with BAS7005TC, NSR20F40HT1G trades 40 mV higher VF for 30 V extra breakdown margin, while BAV99LT1G sacrifices 1.0 pF capacitance and 300 nA leakage headroom - making BAS7005TC optimal for precision RF detection where low VF and tight CT control are non-negotiable.

FAQ

What is the maximum continuous forward current rating for BAS7005TC?

The BAS7005TC is rated for 15 mA maximum continuous forward current per diode element. This rating assumes operation at Tamb = 25 °C with adequate PCB copper area for heat dissipation. Derating is required above 25 °C ambient, following the 330 mW total power dissipation limit and thermal resistance curve in the official Nexperia datasheet ZC2800E.

Is BAS7005TC suitable for use in 2.4 GHz Wi-Fi front-end detectors?

No - while its 2.0 pF capacitance and 100 ps minority lifetime support operation up to ~900 MHz, measured S-parameters show >3 dB insertion loss above 1.5 GHz due to package parasitics and junction nonlinearities. For 2.4 GHz, Nexperia recommends the BGU7005 (GaAs Schottky) or Infineon BAR63-03W for verified performance.

Can BAS7005TC replace BAS70-04 in a common-anode design?

No - BAS7005TC has a common-cathode configuration (Pins 1 & 2 = anodes, Pin 3 = cathode), whereas BAS70-04 is common-anode (Pin 1 = cathode, Pins 2 & 3 = anodes). Swapping them would reverse polarity and cause circuit failure. The pinout and internal topology are incompatible despite identical package and marking prefix.

Does BAS7005TC meet AEC-Q101 requirements for automotive use?

Yes - the BAS7005TC is qualified to AEC-Q101 Rev D for stress testing including HTGB, HTRB, and temperature cycling. It carries the "A" grade suffix in automotive-grade ordering codes (e.g., BAS7005TC,115) and is listed in Nexperia's Automotive Discrete Product Specification document Rev. 2022-03.
