The Infineon BAR6304E6327HTSA1 is a silicon PIN diode configured as a single pair in series, housed in a three-lead SOT-23-3 package (PG-SOT23). The series pair arrangement is common in RF switch and attenuator circuits where two diodes share a common node, reducing PCB area and parasitic inductance compared to two discrete diodes. At 10 mA bias and 100 MHz, the on-state resistance is 1 Ohm; off-state capacitance measures 0.3 pF at 5 V reverse bias and 1 MHz. These numbers place it in the standard-signal RF switching class — suitable for antenna switches, T/R switches, step attenuators, and limiter stages up to several GHz, where the low capacitance preserves isolation and the low resistance keeps insertion loss under a few tenths of a dB.

Product details
Frequently asked questions
Is BAR6304E6327HTSA1 obsolete or end of life?
No. The product status is Active, meaning Infineon continues to manufacture it with no announced discontinuation. There is no last-time-buy or NRND notice to manage.
Is BAR6304E6327HTSA1 RoHS compliant?
Yes, it is ROHS3 compliant, covering the full ten restricted substances including the four phthalates. No exemption paperwork is needed for EU or global markets.
What is the equivalent of BAR6304E6327HTSA1?
The evidence does not list an official cross-reference or second-source alternate. For a pin-compatible alternative, compare other series-pair PIN diodes in SOT-23-3 from Infineon's BAR63 family or from NXP / Skyworks — verify the 1 Ohm on-resistance and 0.3 pF capacitance match your RF bias conditions.
