Infineon Technologies BAS7004WE6327HTSA1

Overview

BAS7004WE6327HTSA1 from Infineon Technologies is a silicon Schottky diode in SOT-323 package configured as a common-cathode dual diode, rated for 70 V reverse voltage, 70 mA forward current, and 250 mW total power dissipation at TS ≤ 48 °C. It delivers low forward voltage (VF = 375–880 mV at IF = 1–15 mA), 1.5–2 pF capacitance at 0 V/1 MHz, and 100 ps reverse recovery time-enabling high-speed switching in signal clamping and RF mixing circuits.

For engineers reviewing the BAS7004WE6327HTSA1 datasheet, BAS7004WE6327HTSA1 pinout, BAS7004WE6327HTSA1 application, or BAS7004WE6327HTSA1 equivalent, key selection criteria include its dual common-cathode topology, thermal derating profile (Ptot = 250 mW only up to TS = 48 °C), VF matching tolerance (≤20 mV), and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This dual Schottky diode integrates two independent anodes sharing a single cathode terminal, enabling compact voltage clamping or signal steering in space-constrained layouts. Its low series inductance (LS = 1.4 nH) and sub-100 ps charge carrier lifetime support operation beyond 1 GHz in RF detector and mixer stages.

The device operates across –55 °C to +125 °C ambient, with junction temperature limited to 150 °C. Thermal resistance from junction to soldering point is 410 K/W, requiring careful PCB copper area design to maintain safe operating limits under continuous 70 mA DC load.

FAQ

Is BAS7004WE6327HTSA1 pin-compatible with BAS70-04W?

Yes-both use SOT-323 package with identical pin 1 (Anode 1), pin 2 (Common Cathode), pin 3 (Anode 2) assignment. BAS7004WE6327HTSA1 replaces BAS70-04W with identical electrical specs and adds full AEC-Q101 qualification and traceable lot marking per Infineon's E6327 tape-and-reel standard.

What is the maximum continuous forward current at 105 °C ambient?

At TA = 105 °C, the device's thermal limit reduces usable forward current to approximately 32 mA, based on its 410 K/W RthJS and 250 mW Ptot rating. Derating curves in Figure 6 of the datasheet confirm IF drops linearly from 70 mA at 48 °C TS to zero at 150 °C TJ.

Can BAS7004WE6327HTSA1 be used in zero-bias RF detector applications?

Yes-its 1.5 pF capacitance, 34 Ω forward resistance, and 100 ps τrr enable effective zero-bias detection at frequencies up to 2.4 GHz. Measured sensitivity reaches –28 dBm at 900 MHz, verified in Infineon Application Note AN245 for TPMS receiver front-ends.

Does this part support reflow soldering with lead-free processes?

Yes-BAS7004WE6327HTSA1 is qualified for IPC/JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature tolerance up to 260 °C for 30 seconds. The SOT-323 package exhibits no warpage or delamination under standard 240–260 °C ramp-to-peak profiles.
