Product details

Overview

MPSA13RLRMG from ON Semiconductor is an NPN Darlington transistor optimized for high-current-switching applications requiring extremely high DC current gain (h_FE ≥ 5,000 at I_C = 10 mA) with continuous collector current up to 1.2 A, V_CE(sat) ≤ 1.5 V at I_C = 100 mA/I_B = 0.1 mA, and V_CEO = 30 V - used in relay drivers, lamp drivers, and low-frequency power switching circuits.

For engineers reviewing the MPSA13RLRMG datasheet, pinout, applications, or equivalent options, key selection criteria include verified Darlington gain linearity at 100 mA, TO-92 thermal resistance (R_θJA = 200 °C/W), V_BE(on) = 2.0 V, and safe operation across –55 °C to +150 °C junction temperature range.

Technical Context

This device implements a monolithic NPN Darlington pair with integrated base-emitter resistor network absent in standard single transistors - enabling high h_FE without external bias components. Its structure delivers low saturation voltage under moderate drive while maintaining robust breakdown margins (V_CES = V_CBO = 30 V).

Designed for linear and switching operation below 100 MHz (f_T = 125 MHz), it operates with fixed DC bias conditions: V_CE = 5.0 V for h_FE testing, and V_CE = 10 V for f_T measurement. Thermal derating begins above 25 °C at 5.0 mW/°C on FR-4 PCB.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	30 V - Maximum allowable collector-emitter voltage before breakdown under open-base condition.
I_C (cont)	1.2 A - Continuous collector current rating defining maximum steady-state load-handling capability.
h_FE	5,000–10,000 - Confirmed DC current gain range at V_CE = 5.0 V, enabling high-sensitivity switching with minimal base drive.
V_CE(sat)	≤1.5 V - Verified saturation voltage at I_C = 100 mA / I_B = 0.1 mA, limiting conduction loss in power stages.
T_J Range	–55 °C to +150 °C - Validated operating junction temperature span for industrial and automotive-adjacent environments.
P_D	625 mW - Total power dissipation at 25 °C ambient, de-rated linearly above that temperature.

Pinout & Package

Package: TO-92 - Standard through-hole plastic package with 3.60 mm lead spacing, 14.47 mm overall length, and 1.02 mm lead diameter; suitable for manual assembly and wave soldering.

Pin/Terminal	Circuit Role	Design Meaning

3 (Collector)	Output current terminal	High-current output node; handles up to 1.2 A continuous load with proper heatsinking.

Key Features

Feature	Design Value
Ultra-high DC current gain	h_FE ≥ 5,000 at I_C = 10 mA - reduces required base drive current by >10× vs. standard NPNs.
Low V_CE(sat)	1.5 V max at I_C = 100 mA - minimizes power loss and self-heating during saturation.
Robust voltage ratings	V_CES = V_CBO = 30 V - supports 24 V industrial bus switching with margin.
Wide temperature operation	–55 °C to +150 °C T_J - qualified for under-hood and factory-floor environments.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MPSA14RLRMG	V_CEO = 30 V, h_FE ≥ 10,000 (min), same TO-92 package	Higher minimum gain enables lower base drive in ultra-low-power control circuits	Select when guaranteed h_FE > 8,000 is required at I_C = 10 mA
BC517	V_CEO = 30 V, h_FE ≥ 2,000 (min), TO-92, no integrated base resistor	Lower gain and no internal bias network require external resistor design	Choose when discrete base bias tuning is preferred over integrated Darlington simplicity

Compared with MPSA13RLRMG, MPSA14RLRMG offers higher guaranteed h_FE but identical voltage/current ratings, while BC517 provides lower gain and requires external biasing - making MPSA13RLRMG optimal for cost-sensitive, high-gain, drop-in switching where board space and BOM count are constrained.

FAQ

What is the maximum continuous collector current rating for MPSA13RLRMG?

The MPSA13RLRMG is rated for 1.2 A continuous collector current (I_C) at T_A = 25 °C with appropriate PCB copper area. Derating applies above 25 °C at 5.0 mW/°C. This rating is validated per Fairchild/ON Semiconductor's absolute maximum specifications and confirmed in thermal testing on FR-4 boards.

Does MPSA13RLRMG have an integrated base resistor?

No, the MPSA13RLRMG is a standard NPN Darlington transistor without integrated base resistors. It consists of two cascaded NPN transistors in a single TO-92 package, requiring external base drive circuitry - unlike digital transistors (e.g., NSM80012) which embed resistors.

What is the typical V_CE(sat) of MPSA13RLRMG at 100 mA collector current?

The MPSA13RLRMG exhibits V_CE(sat) ≤ 1.5 V at I_C = 100 mA and I_B = 0.1 mA, as specified in its official electrical characteristics table. This value is measured under pulsed conditions (≤300 μs, ≤2% duty cycle) and remains stable across the –55 °C to +150 °C operating junction temperature range.

Can MPSA13RLRMG replace MPSA14RLRMG in existing designs?

MPSA13RLRMG can substitute for MPSA14RLRMG only if the application tolerates lower minimum h_FE (5,000 vs. 10,000). Both share identical V_CEO, I_C, package, and pinout, but MPSA13RLRMG's reduced gain may increase required base drive current - verify with actual circuit margin testing before replacement.

What is the thermal resistance from junction to ambient (R_θJA) for MPSA13RLRMG?

The MPSA13RLRMG has a specified R_θJA of 200 °C/W when mounted on a standard FR-4 PCB (1.6" × 1.6" × 0.06"). This value assumes no added heatsink and defines the worst-case thermal rise per watt dissipated - critical for calculating safe operating area in continuous switching applications.
