Product details
Overview
BAP64-02,115 from NXP Semiconductors is a silicon PIN diode in SOD523 package, designed as a voltage-controlled RF resistor for high-frequency switching and attenuation up to 6 GHz. It delivers 0.23 pF diode capacitance at 20 V reverse bias, 2.0 Ω typical forward resistance at 10 mA, and supports 175 V reverse voltage and 100 mA forward current - enabling use in 5G front-end modules and automotive radar switches.
For engineers reviewing the BAP64-02,115 datasheet, BAP64-02,115 pinout, BAP64-02,115 application, or BAP64-02,115 equivalent, key selection criteria include RF isolation performance (−25 dB at 3 GHz), low series inductance (0.6 nH), AEC-Q101 qualification, and SOD523 footprint compatibility with space-constrained RF layouts.
Technical Context
The BAP64-02,115 operates as a current-controlled variable RF resistor, leveraging its intrinsic region to achieve linear resistance control over 0.5–100 mA forward bias. Its low 0.6 nH series inductance and sub-0.35 pF capacitance enable stable impedance behavior through 6 GHz.
Designed for zero-biased or forward-biased operation in series-shunt RF switch topologies, it achieves −25 dB isolation at 3 GHz and <0.5 dB insertion loss at 100 mA bias - validated under 50 Ω stripline conditions per Figures 3 and 4 of the datasheet.

FAQ
What is the maximum operating frequency supported by the BAP64-02,115?
The BAP64-02,115 is characterized for operation up to 6 GHz, with verified isolation (−25 dB) and insertion loss (<0.5 dB) performance at 3 GHz under 50 Ω stripline conditions. Its 0.6 nH series inductance and sub-0.35 pF capacitance ensure stable RF behavior across this range, as confirmed in Figures 3 and 4 of the official NXP datasheet Rev. 11.
Is the BAP64-02,115 qualified for automotive applications?
Yes, the BAP64-02,115 is AEC-Q101 qualified, as explicitly stated in Section 1.2 of the NXP datasheet Rev. 11. This qualification validates its reliability for use in automotive radar, infotainment, and telematics RF modules operating across −40 °C to +125 °C junction temperature ranges.
What does the marking code 'S' indicate on the BAP64-02,115 package?
The marking code 'S' on the BAP64-02,115 corresponds to the type number per Table 3 of the NXP datasheet. The cathode is identified by a marking bar adjacent to pin 1, consistent with the SOD523 package outline in Figure 5 - critical for correct orientation during automated placement in RF-sensitive layouts.
How does forward current affect the RF resistance of the BAP64-02,115?
Forward current directly controls RF resistance: at 0.5 mA, rD is ~40 Ω; at 10 mA, it drops to ~20 Ω; at 100 mA, it reaches 0.7–1.35 Ω (typ/max). This tunable resistance enables precise attenuation in voltage-controlled RF gain stages, as shown in Figure 2 of the BAP64-02,115 datasheet.
What is the thermal resistance from junction to solder point for the BAP64-02,115?
The BAP64-02,115 has a typical thermal resistance Rth(j-sp) of 85 K/W, as specified in Table 5 of the NXP datasheet. This value reflects heat dissipation capability from the silicon junction to the PCB solder point under standard mounting conditions - essential for thermal design in high-duty-cycle RF switch applications.
