Product details
Overview
BAP65-02,135 from NXP Semiconductors is a silicon PIN diode in SOD523 package, designed as an RF switch element with 0.375 pF reverse-biased capacitance at 20 V, 0.35 Ω forward resistance at 100 mA, and AEC-Q101 qualification for automotive-grade reliability. It operates in mobile transmit/receive paths and TV tuner bandswitches.
For engineers reviewing the BAP65-02,135 datasheet, BAP65-02,135 pinout, BAP65-02,135 application, or BAP65-02,135 equivalent, key selection criteria include RF isolation (4.4 dB at 2450 MHz), ultra-low series inductance (0.6 nH), and voltage-controlled RF resistance behavior in high-frequency switching circuits.
Technical Context
The BAP65-02,135 functions as a current-controlled RF resistor: forward bias current modulates its series resistance (0.56–0.9 Ω at 5–10 mA), while reverse bias sets low, voltage-tunable capacitance (0.375–0.65 pF). Its planar PIN structure enables fast carrier lifetime (0.17 μs) for rapid RF switching transitions.
Designed for integration into 50 Ω strip-line circuits, it delivers frequency-dependent insertion loss (0.07–0.13 dB from 900–2450 MHz) and isolation (4.4–10 dB over same range), with thermal resistance of 85 K/W from junction to solder point under Tsp ≤ 90 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF PIN diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon BAR63-02VH6327XTSA1 | Higher Cd (0.5 pF @ 20 V), lower IF rating (50 mA), same SOD523 package | Less suited for high-current TX paths; better for low-power receive switching | Select when forward current remains ≤50 mA and higher capacitance tolerance is acceptable |
| ON Semiconductor MMBD6550LT1G | Higher VR (50 V), larger SOT-23 package, rD = 0.6 Ω @ 10 mA (not specified at 100 mA) | Requires PCB redesign; offers higher surge margin but degraded HF performance above 1 GHz | Choose only if 50 V reverse rating is mandatory and SOD523 size constraint is relaxed |
Compared with BAR63-02VH6327XTSA1 and MMBD6550LT1G, the BAP65-02,135 uniquely balances ultra-low Cd, sub-0.4 Ω rD at full 100 mA drive, and AEC-Q101 compliance in the smallest SMD footprint-making it optimal for space- and power-sensitive automotive and mobile RF switches.

FAQ
What is the maximum continuous forward current rating for the BAP65-02,135?
The BAP65-02,135 has a maximum continuous forward current (IF) rating of 100 mA, as specified in Table 4 of the official NXP datasheet Rev. 6.1. This rating applies under standard ambient conditions and is critical for maintaining forward resistance below 0.35 Ω and avoiding thermal runaway in RF switch designs using the BAP65-02,135.
Does the BAP65-02,135 support automotive qualification standards?
Yes, the BAP65-02,135 is explicitly AEC-Q101 qualified per Section 1.2 of the NXP datasheet. This certification confirms its suitability for automotive applications including infotainment, telematics, and GNSS modules operating across −40 °C to +125 °C junction temperatures, with validation for mechanical shock, temperature cycling, and humidity testing required by the AEC-Q101 standard.
What is the typical diode capacitance of the BAP65-02,135 at 20 V reverse bias?
The typical diode capacitance (Cd) of the BAP65-02,135 is 0.375 pF at VR = 20 V and f = 1 MHz, as stated in Table 6 of the NXP datasheet. This ultra-low value enables high off-state impedance in RF switches up to 2.45 GHz and is measured under controlled thermal conditions (Tj = 25 °C).
How is the cathode identified on the BAP65-02,135 package?
The cathode of the BAP65-02,135 is identified by a marking bar on the top surface of the SOD523 package, corresponding to Pin 1 as defined in Table 1 of the NXP datasheet. This visual indicator aligns with the standardized SOD523 outline in Figure 5 and must be verified during PCB layout and assembly to ensure correct polarity in RF signal paths using the BAP65-02,135.
What is the thermal resistance from junction to solder point for the BAP65-02,135?
The thermal resistance from junction to solder point (Rth(j-sp)) for the BAP65-02,135 is 85 K/W, as specified in Table 5 of the NXP datasheet. This parameter assumes solder point temperature (Tsp) ≤ 90 °C and is essential for calculating junction temperature rise under continuous forward bias, especially in thermally dense RF modules using the BAP65-02,135.
