Product details

Overview

2SD1060R-1E 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; used in high-current switching applications including relay drivers and DC-DC converters.

For engineers reviewing the 2SD1060R-1E datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat) performance at 3 A, h_FE range (100–280), switching times (t_on = 0.1 μs, t_f = 0.2 μs), thermal derating above 25°C, and TO-220AB mechanical compatibility.

Technical Context

This NPN transistor operates as a medium-power switching device with fixed emitter-base and collector-base junction structures optimized for low-loss saturation in linear and pulse-driven configurations. Its gain-bandwidth product of 30 MHz supports fast turn-on/turn-off transitions while maintaining stable DC current gain across 1–2 A operating range.

The device uses epitaxial planar construction with integrated thermal path to case, enabling 30 W dissipation at T_c = 25°C. Saturation voltage remains ≤0.3 V under specified drive conditions, and breakdown ratings (V_(BR)CBO = 60 V, V_(BR)CEO = 50 V) define safe operating area boundaries for inductive load commutation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	50 V - Maximum allowable collector-emitter voltage before avalanche breakdown under open-base condition
I_C (cont)	5 A - Continuous collector current rating at T_c = 25°C; derates linearly above ambient temperature
V_CE(sat)	0.3 V max @ I_C=3 A, I_B=0.3 A - Confirmed low conduction loss enabling efficient high-current switching
h_FE	100–280 @ V_CE=2 V, I_C=1–2 A - Verified DC current gain range supporting reliable base drive design
f_T	30 MHz - Gain-bandwidth product confirming suitability for sub-microsecond switching waveforms
t_on/t_f	0.1 μs / 0.2 μs - Measured turn-on and fall times under standardized 10 Ω load test circuit
P_C (T_c)	30 W @ T_c=25°C - Case-referenced power dissipation limit requiring heatsink for sustained operation

Pinout & Package

Package: TO-220-3L (JEDEC TO-220AB, JEITA SC-46), thermally enhanced through-hole package with metal tab electrically connected to collector; requires insulated mounting hardware when collector is not at chassis ground.

1 (Base)	Control input terminal	Receives forward-biased base current to enable conduction between collector and emitter
2 (Collector)	High-side power terminal	Connected to metal tab; carries full load current and must be electrically isolated if not referenced to system ground
3 (Emitter)	Low-side return terminal	Serves as common reference node for base drive and load return path; typically tied to ground or negative rail

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD127G	V_CEO = 60 V, I_C = 2 A, TO-263 package; lower current rating but higher voltage margin	Better suited for 48 V bus systems where overvoltage protection is prioritized over current capacity	Select MJD127G when V_CEO > 50 V is required and PCB space allows surface-mount layout
2SC5200	V_CEO = 230 V, I_C = 15 A, TO-3P package; significantly higher voltage/current but larger footprint and slower f_T (3 MHz)	Targeted at audio amplifier output stages and high-voltage inverters, not optimized for fast digital switching	Choose 2SC5200 only when >100 V breakdown or >10 A current is mandatory; avoid for 50 V/5 A switching due to excess cost and size

Compared with MJD127G and 2SC5200, the 2SD1060R-1E delivers optimal balance of 50 V rating, 5 A capability, 0.3 V saturation, and TO-220 thermal performance-making it the preferred choice for cost-sensitive, medium-power industrial switching where footprint and thermal management are constrained.

FAQ

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

The 2SD1060R-1E is rated for 5 A continuous collector current (I_C) at case temperature T_c = 25°C. This rating decreases linearly with rising case temperature, reaching zero at T_c ≈ 125°C. Derating curves in the official datasheet (ON Semiconductor document EN686K) confirm usable current down to ~2.5 A at T_c = 80°C. The 2SD1060R-1E must be mounted on an appropriate heatsink to sustain full 5 A operation in real-world conditions.

Does the 2SD1060R-1E have a guaranteed minimum h_FE at 2 A collector current?

Yes - the 2SD1060R-1E guarantees h_FE ≥ 80 at V_CE = 2 V and I_C = 2 A (designated h_FE2 in the datasheet). This is confirmed across both R and S gain bins. The 2SD1060R-1E also provides h_FE ≥ 100 at I_C = 1 A, supporting conservative base drive design for reliable saturation under varying temperature and aging conditions.

Is the collector terminal of the 2SD1060R-1E electrically connected to the metal tab?

Yes - in the TO-220-3L package used by the 2SD1060R-1E, pin 2 (collector) is internally bonded to the metal mounting tab. This requires electrical isolation (e.g., mica washer + shoulder washer) when mounting to a grounded heatsink. Failure to insulate may short the collector to chassis ground, causing immediate device failure. The 2SD1060R-1E datasheet explicitly states this configuration in the "Electrical Connection" diagram.

What is the typical storage time (t_stg) of the 2SD1060R-1E under standard test conditions?

The 2SD1060R-1E has a typical storage time (t_stg) of 1.4 μs, measured using the standardized switching test circuit defined in the datasheet (V_CC = 20 V, R_L = 10 Ω, I_C = 2 A, I_B1/I_B2 ratio = 10). This value reflects minority-carrier removal delay during turn-off and directly impacts maximum usable switching frequency in hard-switched applications. The 2SD1060R-1E's 1.4 μs t_stg supports clean commutation up to ~500 kHz with appropriate base drive optimization.

Can the 2SD1060R-1E be used in avalanche mode for inductive load suppression?

No - the 2SD1060R-1E is not rated or characterized for repetitive avalanche operation. Its absolute maximum V_(BR)CEO = 50 V is a DC breakdown limit under specified test conditions, not an energy-rated avalanche capability. Using the 2SD1060R-1E without external clamping (e.g., flyback diode or RC snubber) across inductive loads risks single-pulse failure. Designers must implement external protection to keep V_CE below 50 V during turn-off transients.
