Product details

Overview

2SD1060R-1EX from onsemi is a low-saturation-voltage NPN bipolar power transistor in TO-220-3L package, rated for 50 V V_CEO, 5 A continuous collector current, and 0.3 V max V_CE(sat) at I_C = 3 A / I_B = 0.3 A. It serves as a high-current switching element in relay drivers, DC-DC converters, and motor control stages.

For engineers reviewing the 2SD1060R-1EX datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat) performance at 3 A, h_FE classification (Rank R: 100–200), thermal derating above 25°C ambient, and TO-220AB mechanical compatibility with standard heatsinks.

Technical Context

This NPN transistor operates in saturation-switching mode with fast turn-on (0.1 μs), storage (1.4 μs), and fall (0.2 μs) times under defined test conditions (V_CC = 20 V, R_L = 10 Ω, I_C = 2 A). Its gain-bandwidth product of 30 MHz supports moderate-frequency switching up to ~100 kHz in hard-switched topologies.

The device features low output capacitance (C_ob = 100 pF at V_CB = 10 V), enabling reduced switching losses in inverter half-bridges. Junction temperature is limited to 150°C, with derated power dissipation (1.75 W at T_a = 25°C, 30 W at T_c = 25°C) requiring case-mounted thermal management.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum safe collector-emitter voltage before breakdown under open-base condition
I_C (cont)	5 A - Continuous collector current rating at T_c = 25°C with heatsink
V_CE(sat)	0.3 V max at I_C = 3 A / I_B = 0.3 A - Enables <1 W conduction loss per device in 3 A load paths
h_FE (Rank R)	100–200 at V_CE = 2 V, I_C = 1 A - Supports stable base drive design with 10–20× current gain margin
f_T	30 MHz - Sufficient for gate driving and sub-100 kHz PWM applications
t_on/t_f	0.1 μs / 0.2 μs - Enables efficient switching in 10–50 kHz power converters
T_j max	150°C - Requires thermal interface design to maintain junction below limit under full load

Pinout & Package

Package: TO-220-3L (JEDEC TO-220AB, JEITA SC-46), through-hole, single-ended heatsink mounting, 3-terminal plastic package with metal tab connected to collector.

Pin/Terminal	Circuit Role	Design Meaning
1 (Base)	Control input	Receives forward-biased base current to saturate transistor; requires current-limiting resistor in series
2 (Collector)	High-side switch node	Connected to metal tab and heatsink; must be electrically isolated from chassis unless common-collector topology used
3 (Emitter)	Power return path	Serves as reference for load current; low-inductance connection critical for switching stability

Key Features

Feature	Design Value
Low V_CE(sat)	0.3 V max at 3 A enables <0.9 W conduction loss, reducing thermal burden in high-duty-cycle operation
Fast switching	0.1 μs turn-on + 0.2 μs fall time supports clean edge transitions in 20–50 kHz inverters
High I_C rating	5 A continuous / 9 A pulse allows direct drive of solenoids, relays, and small BLDC phases without external buffers
Thermal robustness	30 W dissipation at case temperature = 25°C permits use with compact heatsinks in industrial enclosures
Standardized footprint	TO-220AB outline ensures mechanical interchangeability with legacy designs and broad heatsink availability

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SD1761	V_CEO = 60 V, I_C = 5 A, V_CE(sat) = 0.4 V max at 3 A - higher saturation voltage, same package	Preferred where higher V_CEO margin is needed over 50 V, but less efficient at high duty cycles	Select when system transients exceed 50 V and thermal budget allows +0.1 V V_CE(sat) penalty
MJD127G	V_CEO = 100 V, I_C = 8 A, V_CE(sat) = 0.5 V max at 4 A - higher voltage/current, larger TO-263 package	Used in higher-voltage industrial drives; requires PCB layout change and heatsink redesign	Choose only if upgrading to >60 V systems or needing >5 A continuous current with improved SOA

Compared with 2SD1060R-1EX, the 2SD1761 trades lower V_CE(sat) for higher V_CEO headroom, while MJD127G offers greater voltage/current capability at the cost of larger footprint and higher conduction loss - neither is pin-compatible, and both require layout revision.

FAQ

What is the maximum continuous collector current rating for the 2SD1060R-1EX?

The 2SD1060R-1EX is rated for 5 A continuous collector current (I_C) at case temperature T_c = 25°C with adequate heatsinking. At ambient temperature T_a = 25°C without forced cooling, its power dissipation is limited to 1.75 W, which corresponds to approximately 3.5 A under typical V_CE(sat) conditions. Derating curves in the official datasheet must be applied for operation above 25°C ambient or case temperature.

Does the 2SD1060R-1EX have a built-in base-emitter resistor?

No, the 2SD1060R-1EX is a standard three-terminal NPN bipolar transistor without any integrated base-emitter resistors. It requires an external base current limiting resistor to ensure proper saturation and prevent damage during switching. The device's h_FE range (100–200 for Rank R) determines the required base drive, and design calculations must account for worst-case gain and temperature variation.

What is the collector-to-emitter saturation voltage specification for the 2SD1060R-1EX?

The 2SD1060R-1EX has a maximum collector-to-emitter saturation voltage (V_CE(sat)) of 0.3 V at I_C = 3 A and I_B = 0.3 A, measured at T_a = 25°C. This low saturation voltage is confirmed across the specified operating temperature range and directly impacts conduction losses - for example, at 3 A, it contributes just 0.9 W of power dissipation in the transistor itself.

Is the 2SD1060R-1EX RoHS compliant and lead-free?

Yes, the 2SD1060R-1EX is RoHS compliant and lead-free, consistent with onsemi's environmental policy and JEDEC standard packaging for TO-220-3L devices. The device carries the "Pb-Free" marking on its package and meets J-STD-609 Category 3 requirements. Full compliance documentation, including material declarations and test reports, is available through onsemi's official product page and authorized distributor portals.

How does the 2SD1060R-1EX compare to the original 2SD1060 in terms of electrical specifications?

The 2SD1060R-1EX is a specific variant of the 2SD1060 family with h_FE binned to Rank R (100–200 at I_C = 1 A), whereas the base 2SD1060 may be shipped in multiple h_FE ranks (e.g., R or S). All absolute maximum ratings, V_CE(sat), f_T, and switching times remain identical. The "R-1EX" suffix denotes this guaranteed h_FE range and tape-and-reel packaging per JEDEC standards - no electrical parameter differs outside of the specified h_FE bin.
