Product details
Overview
2SC5706-TL-H from onsemi is an NPN bipolar junction transistor (BJT) designed for high-current switching in power control circuits. It delivers 5 A continuous collector current, 50 V VCEO, low 90–135 mV VCE(sat) at 1–2 A, and 400 MHz fT, making it suitable for DC/DC converters and motor drivers.
For engineers reviewing the 2SC5706-TL-H datasheet, pinout, applications, or equivalent options, key selection criteria include verified VCE(sat) performance at 1–2 A, TP-FA package thermal capability, Pb-free & halogen-free compliance, and confirmed SC-63 (TO-252) footprint compatibility.
Technical Context
This device uses FBET and MBIT processes to achieve high-speed switching with low saturation voltage and large current handling. Its 15 W power dissipation at TC = 25°C and 300 ns storage time support robust operation in pulse-driven loads like relay and lamp drivers.
The 2SC5706-TL-H is electrically identical to 2SC5706-TL-E except for halogen-free material content; both share the same TP-FA package, pinout, and full electrical specifications including hFE = 200–560 at IC = 500 mA and Cob = 15 pF at VCB = 10 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage under open-base conditions; defines breakdown margin in switching applications. |
| IC (cont) | 5 A - Continuous collector current rating; supports high-power load switching without derating at TC ≤ 25°C. |
| VCE(sat) @ 1A/50mA | 90–135 mV - Low saturation voltage ensures <135 mW conduction loss at 1 A, critical for efficiency in DC/DC stages. |
| fT | 400 MHz - Gain-bandwidth product enables reliable operation up to ~100 MHz switching frequencies with adequate gain margin. |
| hFE | 200–560 @ VCE=2V, IC=500mA - Wide DC current gain range allows flexible base drive design across operating points. |
| PC @ TC=25°C | 15 W - Case-referenced power dissipation capacity; requires appropriate PCB copper area or heatsinking for sustained loads. |
| Cob | 15 pF @ VCB=10V - Output capacitance impacts turn-off speed and EMI in hard-switched topologies. |
Pinout & Package
2SC5706-TL-H is housed in a TP-FA package - JEITA/JEDEC-recognized as SC-63 and TO-252 - featuring surface-mount construction with exposed drain pad for thermal enhancement. The package measures 7.0 × 5.0 × 2.3 mm (typ), weighs 0.282 g, and uses Pb-free & halogen-free materials.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control terminal; requires ~100 mA drive for full saturation at 2 A collector current. |
| 2 | Collector | Main current input node; electrically tied to exposed thermal pad for low-impedance heat path. |
| 3 | Emitter | Current return path; connected to ground or low-side reference in common-emitter configurations. |
| 4 | Collector | Second collector terminal - paralleled with Pin 2 to reduce bond wire inductance and improve current sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | 90 mV typ at IC = 1 A / IB = 50 mA - reduces conduction losses by >40% vs. standard BJTs in 12 V motor drive stages. |
| High-speed switching | ton = 35 ns, tf = 20 ns - enables clean transitions in 500 kHz–1 MHz PWM circuits with minimal overlap loss. |
| Large current capacity | IC = 5 A continuous, ICP = 7.5 A pulse - supports peak-loaded applications like solenoid actuation without thermal runaway. |
| High power dissipation | 15 W at TC = 25°C - accommodates high-duty-cycle operation when mounted on ≥100 mm² 2-oz copper with thermal vias. |
| Pb-free & halogen-free | Complies with J-STD-609 Class 3 moisture sensitivity and RoHS/REACH requirements - qualified for automotive and industrial assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN high-current switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2SC5706-TL-E | Identical electrical specs and TP-FA package; differs only in Pb-free but not halogen-free construction. | No functional difference in circuit operation; halogen-free requirement drives 2SC5706-TL-H selection for strict environmental compliance programs. | Select 2SC5706-TL-H when J-STD-609 Class 3 or IEC 61249-2-21 halogen-free certification is mandatory. |
| MJD127G | Lower IC = 2 A, higher VCE(sat) = 1.5 V min, TO-252 package but no dual-collector pinout. | Not suitable for >3 A continuous loads; requires larger base drive due to lower hFE (20–100). | Choose MJD127G only for space-constrained legacy designs where 2 A max current and relaxed efficiency targets apply. |
Compared with 2SC5706-TL-E, the 2SC5706-TL-H offers identical performance with enhanced environmental compliance; versus MJD127G, it provides 2.5× higher current capacity and 16× lower VCE(sat), enabling smaller heatsinks and higher system efficiency.

FAQ
What is the maximum continuous collector current rating for the 2SC5706-TL-H?
The 2SC5706-TL-H is rated for 5 A continuous collector current (IC) at case temperature TC = 25°C. Derating is required above this temperature per the PC–TC curve in the datasheet; at TC = 75°C, the usable IC drops to approximately 3.2 A. This rating assumes proper PCB thermal design with ≥100 mm² 2-oz copper and thermal vias under the exposed collector pad.
Does the 2SC5706-TL-H have a dual-collector configuration, and how is it implemented?
Yes, the 2SC5706-TL-H features a dual-collector configuration with Pins 2 and 4 both connected to the collector terminal and electrically tied to the exposed thermal pad. This design reduces bond wire inductance and improves current sharing, directly supporting its 5 A continuous and 7.5 A pulsed current capability. The TP-FA package outline confirms Pins 2 and 4 as collector terminals in the official onsemi drawing No. 6912-7/10.
What is the typical VCE(sat) of the 2SC5706-TL-H at 2 A collector current?
The typical VCE(sat) of the 2SC5706-TL-H at IC = 2 A and IB = 100 mA is 160 mV, with a maximum of 240 mV. This value is specified in the Electrical Characteristics table under "VCE(sat)2" and is measured at TA = 25°C. At elevated temperatures (e.g., 75°C), VCE(sat) increases to ~190 mV typical, as shown in Figure IT02979 of the datasheet.
Is the 2SC5706-TL-H pin-compatible with the 2SC5706-TL-E?
Yes, the 2SC5706-TL-H is fully pin-compatible with the 2SC5706-TL-E - both use the identical TP-FA (SC-63/TO-252) package, share the same 4-pin layout (Base, Collector, Emitter, Collector), and have matching land patterns and thermal pad dimensions. The only difference is halogen-free material content in the 2SC5706-TL-H, with no impact on mechanical fit or electrical interface.
What is the gain-bandwidth product (fT) of the 2SC5706-TL-H, and under what conditions is it measured?
The gain-bandwidth product (fT) of the 2SC5706-TL-H is 400 MHz, measured at VCE = 10 V, IC = 500 mA, and f = 100 MHz. This parameter is specified in the Electrical Characteristics table and confirmed in Figure IT00167. It reflects the transistor's small-signal frequency limit and supports reliable operation in switching applications up to ~100 MHz with sufficient gain margin.
