Product details

Overview

2SC6098-TL-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 100–150 mV V_CE(sat) at I_C=1 A / I_B=100 mA, and 350 MHz f_T, housed in the TP-FA (TO-252) surface-mount package.

For engineers reviewing the 2SC6098-TL-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-compliant TO-252 footprint compatibility.

Technical Context

The 2SC6098-TL-E employs onsemi's FBET and MBIT processes to achieve low V_CE(sat) and high-speed switching performance. Its dual-collector configuration (pins 2 and 4 tied internally) supports higher current handling and improved thermal spreading in power-switching layouts.

Designed for medium-power linear and switching amplification, it operates with V_CEO=80 V, V_CBO=120 V, and a maximum junction temperature of 150°C. The device exhibits h_FE=300–600 at I_C=100 mA and maintains stable gain-bandwidth product (f_T=350 MHz) across its rated current range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum safe collector-emitter voltage before breakdown under open-base conditions; defines upper limit for DC/DC flyback and motor drive bus voltage tolerance.
I_C (cont.)	2.5 A - Continuous collector current rating at T_a=25°C; determines usable load current without forced cooling in relay or lamp driver designs.
V_CE(sat)	100–150 mV @ I_C=1 A, I_B=100 mA - Low saturation voltage minimizes conduction loss and self-heating in high-duty-cycle switching.
f_T	350 MHz - Gain-bandwidth product enabling reliable operation up to ~100 MHz switching frequencies with adequate gain margin.
P_C (T_c=25°C)	15 W - Case-referenced power dissipation capacity; enables high-pulse-current operation when mounted on thermally robust PCB copper areas.
t_on/t_f	40 ns / 32 ns - Fast turn-on and fall times reduce switching losses and EMI generation in PWM-controlled power stages.

Pinout & Package

Package: TP-FA (JEITA SC-63 / JEDEC TO-252), surface-mount, 4-pin single-ended configuration with pins 2 and 4 both connected to the collector terminal for enhanced thermal and current-handling capability.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input node requiring ~100 mA base drive for full saturation at 1 A collector current; low V_BE(sat) (0.9–1.2 V) eases driver design.
2	Collector	Main high-current output terminal; electrically tied to pin 4; used for PCB thermal pad connection and primary current path routing.
3	Emitter	Reference node for load return path; must be routed with low-inductance trace to minimize switching ringing and ensure stable V_CE control.
4	Collector	Duplicate collector terminal; provides second solderable point for thermal relief and mechanical stability; not isolated from pin 2.

Key Features

Feature	Design Value
Low V_CE(sat)	100–150 mV at I_C=1 A / I_B=100 mA reduces conduction loss by >40% vs. standard general-purpose transistors in 24 V motor drives.
High f_T	350 MHz supports clean square-wave switching up to 100 MHz, critical for high-frequency DC/DC converter topologies like synchronous buck.
Dual-collector structure	Pins 2 and 4 both connect to collector, enabling doubled solder joint area and lower thermal resistance to PCB copper pour.
FBET/MBIT process	Enables tight parameter distribution (h_FE = 300–600) and stable V_CE(sat) across temperature, improving batch-to-batch consistency in production.

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=80 V, I_C=2 A, V_CE(sat)=1.5 V @ I_C=1 A - significantly higher saturation voltage and lower current rating.	Less suitable for high-efficiency DC/DC converters; better for low-speed, high-voltage relay driving where loss is less critical.	Select MJD127G only if board layout uses TO-252 but requires higher V_CBO (100 V) and lower cost is prioritized over efficiency.
SSM1002	V_CEO=60 V, I_C=3 A, V_CE(sat)=120 mV @ I_C=2 A - lower voltage rating but higher current and comparable saturation performance.	Preferred for 24–48 V motor drivers needing >2.5 A peak current; unsuitable for 80 V bus applications like certain inverters.	Choose SSM1002 when operating voltage stays ≤60 V and higher continuous current headroom is required for thermal derating margins.

Compared with MJD127G and SSM1002, the 2SC6098-TL-E uniquely balances 80 V V_CEO, 2.5 A I_C, and sub-150 mV V_CE(sat) in TO-252, making it optimal for mid-voltage, medium-current switching where both voltage margin and conduction efficiency are essential.

FAQ

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

The 2SC6098-TL-E has a maximum continuous collector current (I_C) rating of 2.5 A at ambient temperature (T_a) = 25°C. This rating assumes no forced airflow and standard PCB copper area. At elevated temperatures or with limited thermal relief, derating applies per the PC–Ta curve in the datasheet. For sustained 2.5 A operation, mounting on ≥1 in² of 2 oz copper with thermal vias is recommended to maintain junction temperature below 150°C.

Does the 2SC6098-TL-E support high-frequency switching applications?

Yes, the 2SC6098-TL-E supports high-frequency switching with a gain-bandwidth product (f_T) of 350 MHz and measured switching times of t_on = 40 ns and t_f = 32 ns. These characteristics enable reliable use in DC/DC converters operating up to 1 MHz, provided layout minimizes parasitic inductance and base drive strength meets the 100 mA requirement for full saturation at 1 A collector current. The 2SC6098-TL-E's low Cob (14 pF) further supports clean high-speed transitions.

What package type does the 2SC6098-TL-E use, and is it compatible with standard TO-252 footprints?

The 2SC6098-TL-E uses the TP-FA package, which conforms to JEDEC TO-252 (also known as DPAK) and JEITA SC-63 standards. Its land pattern matches industry-standard TO-252 footprints, including pin pitch (2.3 mm), body dimensions (7.0 × 6.5 mm), and thermal pad layout. Pin 1 (Base), pin 2 (Collector), pin 3 (Emitter), and pin 4 (Collector) align with common TO-252-3/4 layouts, allowing drop-in replacement in existing designs using TO-252 components.

How does the dual-collector configuration (pins 2 and 4) of the 2SC6098-TL-E improve thermal performance?

The dual-collector configuration in the 2SC6098-TL-E-where pins 2 and 4 are internally connected to the same collector node-doubles the solderable surface area for thermal conduction to the PCB. This reduces effective thermal resistance from junction-to-board (R_θJB) by up to 25% compared to single-collector TO-252 variants, enabling higher power dissipation (15 W at T_c=25°C) without additional heatsinking. In practice, this allows the 2SC6098-TL-E to sustain 2.5 A continuous current on standard FR-4 with 2 oz copper and thermal vias.

Can the 2SC6098-TL-E replace older 2SC6098-E parts in existing designs?

Yes, the 2SC6098-TL-E is a direct functional and mechanical replacement for the 2SC6098-E, differing only in packaging and reel-based shipping (700 pcs./reel vs. 500 pcs./bag). Both share identical electrical specifications, pinout, thermal characteristics, and marking logic (C6098 + lot code). No PCB layout or schematic changes are needed when migrating from 2SC6098-E to 2SC6098-TL-E, and the TL suffix indicates Pb-free TP-FA packaging compliant with RoHS and JESD22-A113.
