Product details
Overview
MPSA13RLRA from ON Semiconductor is an NPN Darlington transistor optimized for high-current-switching applications requiring extremely high DC current gain (hFE = 5,000–10,000) at collector currents up to 1.0 A, with VCE(sat) ≤ 1.5 V at IC = 100 mA / IB = 0.1 mA, housed in a TO-92 package. It is commonly used in relay drivers, lamp drivers, and low-frequency power switching circuits.
For engineers reviewing the MPSA13RLRA datasheet, pinout, applications, or equivalent options, key selection criteria include verified hFE range, VCE(sat) at specified drive conditions, thermal resistance (RθJA = 200 °C/W), maximum continuous collector current (IC = 1.2 A), and TO-92 mechanical compatibility in space-constrained designs.
Technical Context
The MPSA13RLRA implements a monolithic NPN Darlington pair architecture, delivering high current amplification with integrated base-emitter resistor network absent - requiring external base drive control. Its design supports linear and saturated switching modes, with VBE(on) = 2.0 V at IC = 100 mA and VCE = 5.0 V.
Thermal performance is characterized under FR-4 PCB mounting (1.6" × 1.6" × 0.06"), yielding RθJA = 200 °C/W and PD = 625 mW at TA = 25 °C, derating 5.0 mW/°C above ambient. Breakdown ratings include VCES = VCB0 = 30 V and VEB0 = 10 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCE(sat) | ≤1.5 V at IC = 100 mA, IB = 0.1 mA - ensures low conduction loss in saturated switching |
| hFE | 5,000–10,000 at VCE = 5.0 V, IC = 10–100 mA - enables microampere-level base drive for ampere-level loads |
| IC (continuous) | 1.2 A - supports robust load switching without forced cooling in moderate-duty cycles |
| VCES/VCB0 | 30 V - defines maximum blocking voltage in common-emitter and common-base configurations |
| PD @ 25°C | 625 mW - sets absolute power dissipation limit on standard FR-4 board before thermal derating applies |
| RθJA | 200 °C/W - quantifies junction-to-ambient thermal path efficiency for layout-dependent thermal management |
Pinout & Package
Package: TO-92 - standardized 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.

| 2 (Base) | Control input for internal Darlington pair | Requires external current-limited drive; no internal bias resistor |
| 3 (Collector) | High-side current source terminal | Connected to load and supply rail; handles switched load current |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-high DC current gain | hFE ≥ 5,000 at 10 mA enables single-stage amplification of weak control signals |
| Low saturation voltage | VCE(sat) ≤ 1.5 V reduces power loss and self-heating during on-state operation |

Applications
| Relay Driver Circuit | Lamp and LED Array Driver |
|---|---|
Use Scenario: Driving electromagnetic relays with coil currents up to 100 mA in PLC I/O modules and industrial control panels. IC Role / Device Role / Timing Role: High-gain current amplifier acting as interface between microcontroller GPIO and inductive relay coil. Use Value: Eliminates need for additional pre-driver stages due to hFE ≥ 5,000, simplifying BOM and reducing board area. | Use Scenario: Switching incandescent lamps or high-brightness LED strings (e.g., signage, automotive interior lighting) drawing up to 800 mA. IC Role / Device Role / Timing Role: Low-saturation switch controlling current path to resistive/LED loads in constant-current or PWM-dimmed configurations. Use Value: VCE(sat) ≤ 1.5 V minimizes heat generation and improves system efficiency versus standard bipolar transistors. |
| DC Motor Starter Stage | Low-Frequency Power Amplifier |
Use Scenario: Starting small brushed DC motors (e.g., fans, actuators) in consumer appliances and HVAC controls. IC Role / Device Role / Timing Role: First-stage power switch enabling motor stall current handling up to 1.0 A with minimal base drive. Use Value: IC = 1.2 A rating and 30 V breakdown provide safe margin for motor back-EMF spikes during commutation. | Use Scenario: Audio pre-amplifier output stage or signal-level power buffering in analog instrumentation. IC Role / Device Role / Timing Role: Linear-mode emitter-follower or common-emitter amplifier delivering high-current, low-distortion output. Use Value: High hFE and low VBE(on) = 2.0 V support stable biasing and wide dynamic range in Class-A operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN Darlington transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPSA14RLRA | VCE(sat) = 1.5 V (same), but hFE min = 10,000 - higher minimum gain at IC = 100 mA | Better suited for ultra-low-base-drive designs where guaranteed gain >10k is required | Select MPSA14RLRA when tighter hFE distribution or higher minimum gain is critical |
| BC517 | Same TO-92 package; hFE = 20,000–60,000 min, but VCE(sat) = 1.6 V and IC = 0.5 A - lower current rating | Preferred in low-power, ultra-high-gain signal switching (e.g., sensor interfaces), not high-current loads | Choose BC517 only for sub-500 mA applications where extreme gain outweighs current capacity |
Compared with MPSA13RLRA, MPSA14RLRA offers higher guaranteed hFE with identical saturation and voltage ratings, while BC517 trades current capability for even greater gain - making MPSA13RLRA the balanced choice for 1 A-class Darlington switching where gain, current, and saturation voltage must all be simultaneously optimized.

FAQ
What is the maximum continuous collector current rating for MPSA13RLRA?
The MPSA13RLRA has a maximum continuous collector current (IC) rating of 1.2 A at TA = 25 °C. This rating assumes proper PCB thermal management per the datasheet's FR-4 reference layout. Derating is required above 25 °C at 5.0 mW/°C, and actual usable current depends on ambient temperature, heatsinking, and duty cycle. The MPSA13RLRA is rated for 1.0 A typical operational use in sustained switching applications.
Does MPSA13RLRA include an internal base-emitter resistor?
No, the MPSA13RLRA does not incorporate any internal base-emitter or base-collector resistors. It is a bare Darlington pair structure requiring externally controlled base current. This distinguishes it from digital transistors (e.g., MMBT2222A with R1/R2). Designers must provide appropriate current-limiting resistance in series with the base terminal of the MPSA13RLRA to ensure reliable turn-on and avoid overdrive.
What is the thermal resistance junction-to-ambient (RθJA) for MPSA13RLRA?
The MPSA13RLRA has a specified RθJA of 200 °C/W when mounted on a standard FR-4 PCB (1.6" × 1.6" × 0.06"). This value reflects the total thermal path from silicon junction to surrounding air and is highly dependent on PCB copper area and airflow. For thermally demanding applications, designers should verify junction temperature using TJ = TA + (PD × RθJA) and ensure TJ remains within the −55 °C to +150 °C operating range.
Can MPSA13RLRA replace MPSA14RLRA in existing designs?
MPSA13RLRA and MPSA14RLRA share identical pinout, package, and saturation voltage (VCE(sat) ≤ 1.5 V), but differ in minimum hFE: MPSA13RLRA specifies 5,000, while MPSA14RLRA specifies 10,000. Substituting MPSA13RLRA for MPSA14RLRA may result in insufficient gain in high-impedance or low-base-drive circuits. Verify base current adequacy and worst-case hFE margin before replacement. The MPSA13RLRA is not a drop-in functional replacement unless the design accommodates its lower guaranteed gain.
What is the emitter-base breakdown voltage (VEB0) of MPSA13RLRA?
The emitter-base breakdown voltage (VEB0) of the MPSA13RLRA is rated at 10 V, tested with IE = 0 and VCB = 0. This parameter defines the maximum reverse voltage allowable across the base-emitter junction before avalanche conduction occurs. Exceeding this rating - for example, during inductive flyback or improper biasing - risks permanent junction damage. Always ensure base drive circuitry clamps or limits reverse VEB to ≤10 V in the MPSA13RLRA.
