Product details
Overview
2SD600KE from onsemi is an NPN epitaxial planar silicon power transistor in TO-126 package, rated for 100 V VCEO, 1 A IC, and 1 W PC at Tc = 25 °C, optimized for low-frequency power amplifier and switching applications in industrial control and audio output stages.
For engineers reviewing the 2SD600KE datasheet, pinout, applications, or equivalent options, key selection criteria include verified VCEO = 100 V, hFE ≥ 60 at IC = −50 mA, VCE(sat) ≤ −0.4 V at IC = −500 mA / IB = −50 mA, and TO-126 thermal performance with mica insulator mounting compatibility.
Technical Context
This device operates as a medium-power NPN bipolar junction transistor with fixed-emitter configuration, supporting DC and pulsed operation up to 100 kHz. Its design emphasizes low saturation voltage and linear hFE response across IC = 10 mA to 500 mA, enabling stable Class-A/AB amplifier biasing and relay driver switching.
Thermal derating follows PC = 1 W at Tc = 25 °C, dropping to 0.6 W at Tc = 100 °C, requiring heatsink mounting per mica insulator guidelines. The 2SD600KE shares electrical specs and package with 2SD600K but differs in hFE binning (2SD600KE: hFE = 120–240 at IC = −50 mA, VCE = −5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - Maximum collector-emitter voltage before breakdown under open-base condition; defines safe operating voltage ceiling in amplifier and switch designs. |
| IC | 1 A - Continuous collector current rating; supports load switching up to 1 A DC or pulsed without secondary breakdown risk at Tc ≤ 100 °C. |
| VCE(sat) | −0.4 V max at IC = −500 mA / IB = −50 mA - Low saturation voltage minimizes conduction loss and heat generation in switching applications. |
| hFE | 120–240 at IC = −50 mA, VCE = −5 V - High and linear DC current gain enables precise base drive sizing and stable bias networks. |
| fT | 130 MHz - Transition frequency confirms usable bandwidth up to low-MHz range; suitable for audio and sub-100 kHz switching, not RF. |
| PC | 1 W at Tc = 25 °C - Power dissipation limit sets minimum heatsink requirement; derates linearly to zero at Tc = 150 °C. |
Pinout & Package
2SD600KE uses the TO-126 package (SANYO designation), a through-hole, single-ended power plastic package with integral metal tab for heatsink mounting. The case is electrically connected to the collector terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal | Reference node for current flow; connects to ground or low-side return path in common-emitter configurations. |
| 2 (Collector) | Collector terminal | High-current output node; electrically tied to metal tab and must be insulated from heatsink using mica washer and silicone grease. |
| 3 (Base) | Base control terminal | Low-current input controlling collector current; requires current-limiting resistor to ensure IB ≤ 50 mA for safe 1 A switching. |
Key Features
| Feature | Design Value |
|---|---|
| High breakdown voltage | VCEO = 100 V enables use in 48 V industrial supplies and 24 V relay drivers without derating. |
| Low VCE(sat) | ≤ −0.4 V at rated IC/IB reduces power loss to < 200 mW during saturation, easing thermal management. |
| Linear hFE vs. IC | Stable gain across 10–500 mA supports predictable biasing in Class-A amplifiers and analog current sources. |
| TO-126 thermal interface | Metal tab allows direct heatsink attachment with mica insulation, achieving ≤ 5 °C/W junction-to-case resistance. |
Applications
| Audio Power Amplifier Output Stage | Industrial Relay Driver |
|---|---|
Use Scenario: Final output stage in 5–10 W Class-AB audio amplifiers driving 4–8 Ω speakers. IC Role / Device Role / Timing Role: NPN power switch delivering amplified current to speaker load with minimal crossover distortion. Use Value: VCEO = 100 V accommodates ±35 V rails; low VCE(sat) preserves headroom and reduces thermal stress at full output. |
Use Scenario: Driving 24 VDC industrial relays (coil resistance ~200 Ω) in PLC I/O modules. IC Role / Device Role / Timing Role: Medium-power saturated switch turning relay coil on/off via microcontroller GPIO. Use Value: 1 A IC rating exceeds typical relay coil current (120 mA); hFE ≥ 120 ensures reliable turn-on with ≤ 1 mA base drive. |
| DC Motor Speed Control | Linear Voltage Regulator Pass Element |
Use Scenario: PWM-controlled H-bridge half-bridge leg for 12–24 V brushed DC motors (≤ 500 mA avg). IC Role / Device Role / Timing Role: Low-frequency switching element handling motor current with flyback protection. Use Value: fT = 130 MHz far exceeds PWM frequencies (< 20 kHz); TO-126 package supports heatsinking during stall conditions. |
Use Scenario: Series pass transistor in adjustable 3–15 V, 500 mA linear regulators for sensor signal conditioning. IC Role / Device Role / Timing Role: Current-amplifying element controlled by error amplifier to regulate output voltage. Use Value: Linear hFE ensures stable loop gain; VCEO = 100 V allows > 30 V input headroom for wide-input-range designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJD127G | VCEO = 100 V, IC = 2 A, TO-220 package, hFE = 1000–2000 at IC = 1 A - higher gain, higher current, larger footprint. | Requires PCB layout change due to TO-220 vs. TO-126; better suited for >1 A continuous loads but over-specified for 2SD600KE's 1 A target. | Select MJD127G only if higher current headroom and TO-220 heatsink compatibility are required; not drop-in. |
| 2SC2625 | VCEO = 120 V, IC = 1 A, TO-126, hFE = 60–120 - lower gain binning, same package and voltage rating. | Acceptable in relay drivers where hFE ≥ 60 suffices, but may require increased base drive in amplifier bias networks. | Choose 2SC2625 when cost sensitivity outweighs gain linearity needs; verify base resistor recalibration for hFE min. |
Compared with 2SD600KE, MJD127G offers higher current capacity and gain but demands TO-220 layout changes, while 2SC2625 matches the TO-126 form factor and voltage rating but trades hFE linearity for lower cost and reduced gain margin.

FAQ
What is the maximum collector-emitter voltage rating for the 2SD600KE?
The 2SD600KE has a maximum collector-emitter voltage rating of VCEO = 100 V under open-base conditions at Ta = 25 °C. This rating remains valid up to Tj = 150 °C, with no additional derating required below that junction temperature. Exceeding this voltage risks avalanche breakdown and permanent device failure.
Does the 2SD600KE have a built-in base-emitter resistor?
No, the 2SD600KE is a standard three-terminal NPN bipolar transistor with no integrated base-emitter resistor. External base drive circuitry-including current-limiting resistors-must be provided to ensure proper biasing and avoid thermal runaway. Its pinout (Emitter-Collector-Base) requires discrete resistor networks for reliable switching or amplification.
What is the thermal resistance junction-to-case for the 2SD600KE?
The 2SD600KE has a typical junction-to-case thermal resistance (RθJC) of 5 °C/W when mounted with mica insulator and silicone grease on a 100 × 100 × 1.5 mm aluminum heatsink. This value assumes full metal-tab contact and is critical for calculating allowable power dissipation at elevated case temperatures.
Is the 2SD600KE RoHS compliant and lead-free?
Yes, the 2SD600KE is RoHS compliant and lead-free per onsemi's packaging standards effective from 2006 onward. The TO-126 package uses matte tin-plated leads and halogen-free molding compound, meeting JEDEC J-STD-609 Category 1 requirements for lead-free soldering processes.
How does the hFE binning of 2SD600KE differ from 2SD600K?
The 2SD600KE is binned for hFE = 120–240 at IC = −50 mA and VCE = −5 V, whereas the 2SD600K is binned for hFE = 60–120 under identical conditions. This higher-gain bin makes the 2SD600KE preferable in low-base-drive applications like microcontroller-driven switches or high-stability amplifier bias networks.
