Nexperia USA Inc. PMBT2369,215

Overview

PMBT2369 from Nexperia is an NPN bipolar junction transistor optimized for high-speed switching in low-voltage, low-current applications, with V_CEO = 15 V, I_C = 200 mA (DC), f_T = 500 MHz, and t_off = 20 ns. It serves as a compact, SOT23-packaged switch in portable battery-powered logic interfaces and signal routing circuits.

For engineers reviewing the PMBT2369 datasheet, PMBT2369 pinout, PMBT2369 application, or PMBT2369 equivalent, key selection criteria include its 10 ns turn-on time, 700–850 mV V_BE(sat) at I_C = 10 mA/I_B = 1 mA, 4 pF collector capacitance, and suitability for 2.7 V supply rail switching in space-constrained designs.

Technical Context

This NPN transistor operates in active and saturation regions for digital switching, not linear amplification. Its DC current gain (h_FE) ranges from 40 to 120 at I_C = 10 mA/V_CE = 1 V, and drops to ≥20 at I_C = 100 mA/V_CE = 2 V - confirming robust gain retention under moderate load.

Thermal resistance R_th(j-a) is 500 K/W on FR4 PCB, limiting continuous power dissipation to 250 mW at T_amb ≤ 25 °C. Switching performance is characterized using standardized test circuit (Fig.2) with defined R_B, R_C, and probe impedances - ensuring reproducible timing measurements.

FAQ

Is PMBT2369 suitable for linear amplification?

No. The PMBT2369 is characterized and specified exclusively for switching operation. Its h_FE variation (40–120), lack of linearity data, and optimized f_T/C_c trade-offs confirm it is not intended for analog amplification. Use dedicated RF or general-purpose amplifiers like BC847 for such roles.

What is the maximum operating temperature for continuous use?

The PMBT2369 has a maximum junction temperature (T_j) of 150 °C and an operating ambient range of −65 °C to +150 °C. At 25 °C ambient, its 250 mW P_tot and 500 K/W R_th(j-a) allow ~125 °C junction rise - so continuous use at full I_C requires ambient ≤25 °C unless board-level thermal enhancements are applied.

Can PMBT2369 replace BC817 in existing designs?

Not directly. BC817 has V_CEO = 45 V and I_C = 500 mA - significantly higher ratings than PMBT2369's 15 V/200 mA. Substitution is only viable if the original design operates well within PMBT2369's lower limits and does not rely on its higher voltage/current headroom.

Does PMBT2369 have built-in ESD protection?

No. The datasheet specifies no human-body model (HBM) or charged-device model (CDM) ESD ratings. Handling requires standard ESD precautions (e.g., grounded workstations, ionized air). For ESD-critical environments, consider Nexperia's PESD-series transient protectors or ESD-hardened alternatives like PMBTA13.
