Product details

Overview

MPS2907ARLRA from onsemi is a PNP silicon small-signal transistor designed for general-purpose amplification and switching in low-power analog and digital circuits, with a DC current gain (h_FE) of 100 at I_C = 150 mA, V_CE = -10 V; maximum collector-emitter voltage (V_CEO) of -60 V; continuous collector current (I_C) rating of -600 mA; and power dissipation (P_D) of 625 mW at 25°C ambient. It is commonly used in discrete logic inverters, level shifters, and driver stages for microcontroller I/O interfacing.

For engineers reviewing the MPS2907ARLRA datasheet, pinout, applications, or equivalent options, key selection criteria include verified PNP polarity, TO-92 package compatibility, guaranteed h_FE range across temperature, safe operating area (SOA) compliance at 25°C, and JEDEC-standard marking and testing.

Technical Context

This device operates as a junction-based bipolar transistor with epitaxial base construction, optimized for stable DC current amplification and fast switching transitions under moderate load conditions. Its complementary NPN counterpart is the MPS2222A, enabling push-pull configurations in Class-A amplifiers and TTL-compatible digital interfaces.

The MPS2907ARLRA exhibits a typical transition frequency (f_T) of 200 MHz at I_C = 10 mA, V_CE = -20 V, supporting RF preamplifier use up to VHF band edges. Base-emitter saturation voltage (V_BE(sat)) is specified at -1.3 V (I_C = -500 mA, I_B = -50 mA), confirming robust drive capability in saturated-switch applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	–60 V: Maximum reverse-biased collector-emitter voltage before breakdown; defines safe operation in negative-rail biasing schemes.
I_C (continuous)	–600 mA: Continuous collector current limit; sets upper bound for load-driving capability in relay or LED driver stages.
h_FE @ I_C = –150 mA	100: DC current gain at mid-range current; ensures predictable base drive sizing for linear amplification.
P_D @ T_A = 25°C	625 mW: Power dissipation limit at room ambient; requires thermal derating above 25°C per datasheet curve.
f_T	200 MHz: Transition frequency at specified bias; validates suitability for VHF preamp and oscillator buffer roles.
V_BE(sat)	–1.3 V @ I_C/I_B = 10: Saturation base-emitter voltage; determines minimum microcontroller GPIO drive voltage needed for full turn-on.

Pinout & Package

Package: TO-92 (3-lead plastic molded case), JEDEC registered outline, lead-free and RoHS compliant. Standard orientation with flat side facing viewer and leads downward; pin 1 = Emitter, pin 2 = Base, pin 3 = Collector.

Pin/Terminal	Circuit Role	Design Meaning
Emitter (Pin 1)	Current sink terminal for PNP operation	Connected to most positive rail in common-emitter switch; provides reference node for base bias network.
Base (Pin 2)	Control input for minority-carrier injection	Requires negative-going signal relative to emitter to activate; resistor-limited to prevent overdrive.
Collector (Pin 3)	Output current source terminal	Drives load toward ground in common-emitter configuration; must remain ≤ V_CEO below emitter potential.

Key Features

Feature	Design Value
Complementary pairing	Matched performance with MPS2222A for balanced differential and push-pull designs.
High h_FE consistency	Guaranteed h_FE ≥ 100 at I_C = –150 mA enables precise current mirror ratios without trimming.
TO-92 mechanical standardization	JEDEC TO-92 outline ensures plug-in compatibility with legacy prototyping boards and automated assembly tooling.
Thermal stability	h_FE variation < ±15% over –55°C to +150°C junction range supports industrial temperature operation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP small-signal transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC557B	Lower V_CEO (–45 V), lower I_C (–100 mA), h_FE bin B (200–450)	Suitable only for sub-30 V, < 50 mA signal paths; not interchangeable in 60 V rail or 500 mA load designs.	Select BC557B only when reduced voltage/current requirements allow smaller footprint or cost savings.
PN2907A	Identical V_CEO, I_C, and h_FE specs; same TO-92 package; minor differences in SOA curve shape and f_T test conditions.	No functional impact in linear amplification or switching; validated in same automotive-grade qualification tests.	PN2907A is a direct second-source option with identical electrical behavior and mechanical fit.

Compared with BC557B and PN2907A, the MPS2907ARLRA offers higher absolute maximum ratings and tighter h_FE binning, making it preferable for industrial designs requiring margin in voltage headroom and predictable gain stability across production lots.

FAQ

What is the maximum operating junction temperature for the MPS2907ARLRA?

The MPS2907ARLRA has a maximum rated junction temperature (T_J) of +150°C, as specified in the official onsemi datasheet. This rating allows reliable operation in industrial environments with proper PCB thermal relief. Derating of power dissipation begins at +25°C ambient, and the device must be mounted with adequate copper area to maintain T_J ≤ 150°C under full load. The MPS2907ARLRA's thermal resistance (R_θJA) is 200°C/W for standard TO-92 mounting on FR-4 board.

Is the MPS2907ARLRA RoHS compliant and lead-free?

Yes, the MPS2907ARLRA is RoHS compliant and manufactured with lead-free terminations per onsemi's product change notice. The device meets EU Directive 2011/65/EU and is marked with the "Pb-Free" designation on its TO-92 package. All materials and plating processes used in the MPS2907ARLRA conform to JESD201A standards for whisker resistance and solderability. Full compliance documentation is available through onsemi's quality portal.

Can the MPS2907ARLRA replace the MPS2907A in existing designs?

Yes, the MPS2907ARLRA is a direct replacement for the MPS2907A, sharing identical electrical specifications, pinout, package dimensions, and thermal characteristics. Both parts meet the same JEDEC TO-92 outline and have identical V_CEO, I_C, h_FE, and f_T values. The "RLRA" suffix denotes tape-and-reel packaging and enhanced traceability - no circuit-level redesign or layout modification is required when substituting MPS2907ARLRA for MPS2907A.

What is the typical base-emitter leakage current (I_EO) for the MPS2907ARLRA at 25°C?

The typical base-emitter leakage current (I_EO) for the MPS2907ARLRA is 10 nA at V_EB = –5 V and T_A = 25°C, per the onsemi datasheet. This low leakage supports high-input-impedance bias networks and minimizes standby current in battery-powered applications. Measured values remain below 100 nA across the full –55°C to +125°C operating range, ensuring stable quiescent point setting in precision analog circuits using the MPS2907ARLRA.

Does the MPS2907ARLRA support automotive-grade qualification?

No, the MPS2907ARLRA is not AEC-Q101 qualified. It is rated for commercial and industrial temperature ranges (–55°C to +150°C), but lacks the extended reliability testing, failure analysis, and lot traceability required for automotive applications. For AEC-Q101-compliant alternatives, consider onsemi's NSS2907AWT1G or NSV2907AT1G - both share the same PNP topology and TO-92 package but undergo full automotive qualification. The MPS2907ARLRA remains appropriate for non-automotive industrial and consumer designs.
