Product details

Overview

MMBT2907A-D87Z from ON Semiconductor is a 60 V PNP bipolar junction transistor in SOT-23 package, rated for continuous collector current up to −800 mA and DC current gain (h_FE) of 100–300 at −10 mA. It delivers 200 MHz minimum f_T, 45 ns max turn-on time, and −0.4 V V_CE(sat) at −150 mA/−15 mA - used as a general-purpose switch or amplifier in low-voltage power control circuits.

For engineers reviewing the MMBT2907A-D87Z datasheet, pinout, applications, or equivalent options, key selection criteria include verified PNP switching speed, SOT-23 thermal derating (2.8 mW/°C), −60 V V_CEO rating, and confirmed E-B-C terminal mapping per JEDEC TO-236AB.

Technical Context

This device operates as a standard PNP BJT with fixed emitter-base and collector-base breakdown voltages (−5.0 V and −60 V respectively), supporting linear amplification and saturated switching modes. Its h_FE remains ≥100 across −1 mA to −150 mA collector currents, enabling stable biasing in discrete gain stages and digital logic interface circuits.

Switching performance is defined by measured ton/toff (45 ns / 100 ns) under specified test conditions (V_CC = −30 V, I_C = −150 mA), with Cob = 8.0 pF and Cib = 30 pF confirming suitability for <100 MHz signal paths. Thermal resistance R_θJA = 357 °C/W reflects SOT-23's surface-mount thermal limitations on FR-4 PCBs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V - Maximum safe collector-emitter voltage before breakdown; defines rail compatibility in negative-supply switching applications.
I_C (cont.)	−800 mA - Continuous collector current limit; supports load switching up to ~0.8 A with appropriate heatsinking.
h_FE	100–300 - DC current gain range at −10 mA; enables predictable base drive sizing for saturation in switching designs.
f_T	≥200 MHz - Minimum current-gain bandwidth product; confirms usable frequency response for audio and low-speed digital signal amplification.
t_on/t_off	45 ns / 100 ns - Verified turn-on/turn-off times under standardized test conditions; informs maximum PWM frequency capability.
R_θJA	357 °C/W - Junction-to-ambient thermal resistance on standard FR-4; dictates power dissipation limits without forced cooling.

Pinout & Package

SOT-23 (JEDEC TO-236AB) 3-lead plastic surface-mount package with gull-wing leads; 2.92 mm × 1.30 mm footprint, 1.20 mm max height, and recommended land pattern per ON Semiconductor MA03DREV10.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	E	Current source terminal in PNP operation; connects to higher potential (e.g., V_CC) in common-emitter switch configurations.
2 (Base)	B	Control input; requires negative current relative to emitter to forward-bias BE junction and enable conduction.
3 (Collector)	C	Current sink terminal; connects to load and lower-potential node (e.g., ground or negative rail) in typical switching layouts.

Key Features

Feature	Design Value
High h_FE range	100–300 ensures consistent base drive requirements across production lots and temperature ranges (−55°C to +150°C).
Fast switching	45 ns t_on/100 ns t_off enables reliable operation in 1–5 MHz PWM circuits without excessive switching losses.
Low V_CE(sat)	−0.4 V at −150 mA/−15 mA reduces conduction loss and self-heating in high-duty-cycle switching applications.
SOT-23 footprint	Standardized 3-pin surface-mount package allows automated assembly and board space savings versus through-hole TO-92 variants.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP general-purpose transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT2907ALT1G	Same SOT-23 package, identical electrical specs per ON Semi datasheet; top mark "2F" vs "2F" - functionally identical part number variant.	No functional difference; both qualified for same industrial temperature range and reliability testing.	Select MMBT2907ALT1G if sourcing from distributors listing that specific suffix; no design change required.
PN2907A	TO-92 through-hole package; same V_CEO, h_FE, and f_T, but higher PD (625 mW) and lower R_θJA (200 °C/W).	Requires manual or wave soldering; unsuitable for high-density SMT layouts but offers better thermal performance in low-volume prototyping.	Choose PN2907A only for hand-soldered prototypes or legacy through-hole designs where SMT is unavailable.

Compared with MMBT2907A-D87Z, MMBT2907ALT1G is a functionally identical SOT-23 variant with identical marking and qualification, while PN2907A provides equivalent electrical performance in a larger through-hole package with superior thermal dissipation but incompatible mounting.

FAQ

What is the maximum collector-emitter voltage rating for MMBT2907A-D87Z?

The MMBT2907A-D87Z has a guaranteed minimum V_CEO rating of −60 V, meaning it can safely block up to 60 V between collector and emitter with base open. This rating is validated per ON Semiconductor's absolute maximum ratings table and applies across the full operating temperature range of −55°C to +150°C.

Does MMBT2907A-D87Z support high-frequency switching applications?

Yes, the MMBT2907A-D87Z delivers a minimum current-gain bandwidth product (f_T) of 200 MHz and verified switching times of 45 ns t_on and 100 ns t_off, making it suitable for high-frequency switching up to several megahertz in properly biased circuits with controlled layout parasitics.

What is the pin configuration of MMBT2907A-D87Z in the SOT-23 package?

The MMBT2907A-D87Z uses standard JEDEC TO-236AB pinout: Pin 1 is Emitter, Pin 2 is Base, and Pin 3 is Collector - confirmed by ON Semiconductor's physical dimensions drawing MA03DREV10 and device marking "2F" orientation diagrams.

How does the thermal performance of MMBT2907A-D87Z compare to through-hole versions?

The MMBT2907A-D87Z has R_θJA = 357 °C/W on standard FR-4, significantly higher than the TO-92 PN2907A's 200 °C/W.
