onsemi 2SC6098-E

Overview

2SC6098-E from onsemi is an NPN bipolar junction transistor optimized for switching applications including DC/DC converters, relay drivers, lamp drivers, motor drivers, and inverters. It delivers 2.5 A continuous collector current, 80 V V_CEO, low 100–165 mV V_CE(sat) at I_C=1 A / I_B=100 mA, and 350 MHz f_T, housed in the TP (TO-251) package with 4-pin configuration.

For engineers reviewing the 2SC6098-E datasheet, pinout, applications, or equivalent options, key selection criteria include saturation voltage under high-current drive, thermal dissipation capability at T_c=25°C (15 W), switching speed (t_on=40 ns, t_f=32 ns), and JEDEC SC-64 compliance for surface-mount reliability in power interface circuits.

Technical Context

The 2SC6098-E employs onsemi's FBET and MBIT processes to achieve low V_CE(sat) and high-speed switching performance. Its dual-collector structure (pins 2 and 4) supports higher current handling and improved thermal spreading in TO-251 outline.

Designed for medium-power switching, it operates with V_CEO=80 V, V_CB0=120 V, and V_EBO=6.5 V - enabling robust operation in 48 V bus systems and industrial control interfaces where overvoltage transients occur.

FAQ

What is the maximum continuous collector current rating for the 2SC6098-E?

The 2SC6098-E has a maximum continuous collector current (I_C) rating of 2.5 A at case temperature T_c = 25°C. This rating assumes proper thermal management via PCB copper area or heatsink attachment to the exposed collector tab. At ambient temperature (T_a = 25°C), the derated I_C drops to 0.8 A due to lower thermal resistance to ambient. Always reference the PC–Ta and PC–Tc derating curves in the 2SC6098-E datasheet for design-specific limits.

Does the 2SC6098-E support surface-mount assembly, and what is its land pattern requirement?

Yes, the 2SC6098-E uses the TP package (JEDEC TO-251), a surface-mount variant with gull-wing leads and an exposed collector pad. Its recommended land pattern follows JEITA SC-64 standards: 7.0 mm × 2.5 mm body outline, 2.3 mm lead pitch, and ≥100 mm² copper pour under the collector tab for thermal relief. The 2SC6098-E land pattern must accommodate both pins 2 and 4 as collector connections and ensure solder fillet formation on all four terminals per IPC-7351B.

How does the dual-collector configuration (pins 2 and 4) affect PCB layout for the 2SC6098-E?

The dual-collector configuration in the 2SC6098-E (pins 2 and 4) requires both terminals to be routed to the same high-current net - typically the positive rail or heatsink plane. This design increases current-carrying capacity and spreads thermal load across two parallel paths. In PCB layout, short, wide traces (≥0.5 mm width) must connect both pins directly to the same copper pour, avoiding stubs or vias that could unbalance current sharing. Failure to tie pins 2 and 4 together compromises the 2SC6098-E's specified 2.5 A rating and thermal performance.

What is the typical V_CE(sat) of the 2SC6098-E under standard switching conditions?

The typical V_CE(sat) of the 2SC6098-E is 100 mV at I_C = 1 A and I_B = 100 mA, with a maximum of 150 mV under those same conditions. At lower drive (I_B = 50 mA), V_CE(sat) rises to 110–165 mV. This low saturation voltage is achieved via onsemi's FBET process and enables high-efficiency operation in battery-powered and thermally constrained 2SC6098-E applications such as portable motor controllers and LED drivers.

Is the 2SC6098-E pin-compatible with other TO-251 transistors like the MJD31C?

No, the 2SC6098-E is not pin-compatible with MJD31C or most standard TO-251 NPN transistors. While both use the TO-251 outline, the 2SC6098-E features a unique 4-pin configuration (Base, Collector, Emitter, Collector), whereas MJD31C uses the conventional 3-pin TO-251 layout (Base, Collector, Emitter). Interchanging them requires PCB redesign to accommodate the extra collector pin and revised routing - the 2SC6098-E's pinout is specific to its dual-collector architecture and cannot be substituted without layout changes.
