Product details

Overview

PMBTA14,215 from Nexperia is an NPN general-purpose bipolar junction transistor (BJT) with 300 mA I_C, 30 V V_CEO, and 100–250 h_FE at I_C = 10 mA, used in low-power switching and linear amplification circuits such as LED drivers and signal buffering in consumer electronics.

For engineers reviewing the PMBTA14,215 datasheet, PMBTA14,215 pinout, PMBTA14,215 application, or PMBTA14,215 equivalent, key selection criteria include DC current gain consistency at low collector currents, saturation voltage under 10 mA drive, SOT-23 package thermal performance, and compatibility with 3.3 V/5 V logic-level control signals.

Technical Context

The PMBTA14,215 operates as a medium-gain, low-voltage NPN BJT optimized for base-driven switching in discrete logic interface stages. Its h_FE range is specified at I_C = 10 mA and V_CE = 1 V, and it supports continuous collector currents up to 300 mA with a maximum power dissipation of 250 mW at T_amb = 25 °C.

It features a complementary PNP counterpart (PMBTA13,215), shares the same SOT-23 footprint as other Nexperia BJT families like BC847, and is rated for operation from −65 °C to +150 °C ambient temperature.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN switching transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC847B,215	Same SOT-23 package; h_FE = 200–450 at I_C = 10 mA - higher and wider gain range	Better suited for precision analog amplification; less predictable saturation in digital switching due to gain spread	Select BC847B,215 only if higher h_FE is required and base drive can be adjusted accordingly
MMBT3904LT1G	Same pinout and basic ratings; V_CEO = 40 V, P_D = 310 mW - higher voltage and power headroom	Preferred in 36 V automotive subsystems or where transient overvoltage immunity is critical	Choose MMBT3904LT1G when operating near 30 V rails or requiring extended thermal margin

Compared with BC847B,215 and MMBT3904LT1G, the PMBTA14,215 offers tighter h_FE tolerance at low currents and lower V_CE(sat), making it more predictable in logic-driven switching where base current is fixed and saturation margin is constrained.

FAQ

What is the maximum continuous collector current rating for PMBTA14,215?

The PMBTA14,215 has a maximum continuous collector current (I_C) rating of 300 mA at T_amb = 25 °C. Derating is required above 25 °C ambient, with linear reduction to zero at 150 °C. This rating assumes proper PCB copper area for heat dissipation and excludes pulsed operation allowances.

Is PMBTA14,215 suitable for use as a low-side switch with 3.3 V microcontroller GPIOs?

Yes, the PMBTA14,215 is well-suited for low-side switching with 3.3 V GPIOs. At I_B = 100 µA, it achieves full saturation with I_C up to 10 mA. For 30 mA loads, a 33 kΩ base resistor ensures reliable turn-on while staying within GPIO current limits - verified in Nexperia's application note AN10273.

What is the typical V_CE(sat) of PMBTA14,215 at I_C = 10 mA and I_B = 0.5 mA?

The typical V_CE(sat) of PMBTA14,215 under those conditions is 0.1 V, with a maximum of 0.3 V across the −65 °C to +150 °C temperature range. This low saturation voltage reduces power loss and improves efficiency in battery-powered switching applications using the PMBTA14,215.

Does PMBTA14,215 have a qualified AEC-Q200 grade for automotive use?

No, the standard PMBTA14,215 is not AEC-Q200 qualified. However, Nexperia offers the automotive-grade variant PMBTA14,235 (with extended temperature screening and traceability), which meets AEC-Q200 Rev D requirements for passive components and discrete semiconductors.

Can PMBTA14,215 replace BC847B in existing SOT-23 designs?

The PMBTA14,215 is pin-compatible with BC847B in SOT-23 layout but differs in h_FE range (100–250 vs. 200–450) and V_CE(sat) (0.1 V vs. 0.07 V typical). Circuit validation is recommended for BC847B-replacement use of PMBTA14,215, especially where base drive current or gain stability is critical.
