Product details

Overview

2SC4488T-AN from onsemi is an NPN bipolar junction transistor designed for high-voltage switching applications, featuring V_CEO = 100 V, I_C = 1 A, f_T = 120 MHz, V_CE(sat) = 0.1–0.4 V at I_C = 400 mA, and SC-71 (NMP) package. It serves as a fast-switching power switch in DC-DC converters and motor drivers.

For engineers reviewing the 2SC4488T-AN datasheet, pinout, applications, or equivalent options, key selection criteria include its low saturation voltage, high breakdown rating, fast switching times (t_on = 80 ns, t_f = 40–50 ns), and h_FE rank T (200–400) for consistent gain control in amplification and switching circuits.

Technical Context

The 2SC4488T-AN employs FBET and MBIT processes to achieve high breakdown voltage and low V_CE(sat), enabling efficient operation in medium-power linear and switching topologies. Its f_T of 120 MHz supports RF amplifier stages up to UHF, while Cob = 8.5 pF at V_CB = –10 V ensures minimal Miller effect in high-speed switching.

Designed for single-transistor configurations, it operates with V_BE(sat) = –0.85 to –1.2 V and exhibits stable h_FE across –25°C to +75°C ambient, making it suitable for automotive and industrial temperature-critical designs without external bias compensation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	100 V - Supports rail voltages up to 80 V DC with 20% safety margin in switching supplies.
I_C	1 A continuous - Handles load currents in small-motor drivers and relay drivers without heatsinking.
f_T	120 MHz - Enables use in VHF amplifiers and fast PWM gate driving up to ~20 MHz effective switching.
V_CE(sat)	0.1–0.4 V @ I_C=400 mA - Reduces conduction loss to ≤160 mW, improving efficiency in battery-powered systems.
h_FE Rank	T (200–400) - Tighter gain distribution than S-rank, simplifying bias network design in linear amplifiers.
t_f	40–50 ns - Limits switching transition losses in 100–500 kHz SMPS designs with minimal snubbing.
C_ob	8.5 pF @ V_CB=–10 V - Minimizes capacitive loading on driver stages and preserves rise/fall edge integrity.

Pinout & Package

Package: SC-71 (JEITA/IEC designation), also labeled NMP(Taping) by onsemi; surface-mount, 3-pin, plastic molded case with 2.54 mm lead pitch and 0.275 g mass.

Pin/Terminal	Circuit Role	Design Meaning
1	Emitter	Current sink node; connects to ground or low-side return path in common-emitter switches.
2	Collector	High-current output node; ties to load or supply rail in low-side switching configurations.
3	Base	Control input; requires ~40 mA drive for full saturation at I_C = 400 mA per h_FE ≥200.

Key Features

Feature	Design Value
Low V_CE(sat)	0.1 V typical enables <100 mW conduction loss at 400 mA, reducing thermal stress in compact layouts.
High V_CEO	100 V rating allows direct interface with 48 V industrial buses and 60 V automotive subsystems.
Fast switching	80 ns turn-on and 40–50 ns fall time support >1 MHz PWM in Class-D audio and digital power stages.
Stable h_FE over temperature	Minimal gain shift from –25°C to +75°C avoids bias drift in unregulated amplifier bias networks.
SC-71 package	Standardized JEITA footprint enables drop-in replacement and compatibility with automated pick-and-place equipment.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD127G	V_CEO = 100 V, I_C = 2 A, but f_T = 3 MHz - significantly slower switching and higher V_CE(sat) (0.5 V min).	Suitable only for <50 kHz linear or switching use; not viable for RF or high-frequency SMPS.	Select when higher current headroom is needed and speed is secondary; verify thermal derating at 2 A.
BC817-40,215	V_CEO = 45 V, I_C = 0.5 A, SOT-23 package - lower voltage/current rating and smaller package limits power handling.	Limited to sub-24 V logic-level switching; unsuitable for 48 V bus or motor drive applications.	Choose only for space-constrained low-power signal switching where 100 V capability is unnecessary.

Compared with MJD127G and BC817-40,215, the 2SC4488T-AN uniquely balances 100 V breakdown, 1 A current, 120 MHz f_T, and low saturation voltage-making it optimal for medium-power, medium-frequency switching where both voltage margin and speed matter.

FAQ

What is the h_FE range for the 2SC4488T-AN?

The 2SC4488T-AN is ranked "T", specifying a DC current gain (h_FE) range of 200 to 400 at V_CE = –5 V and I_C = –100 mA. This tighter binning than the "S" rank (140–280) improves predictability in bias-critical amplifier and switching designs without requiring gain feedback or trimming.

Is the 2SC4488T-AN RoHS and Pb-free compliant?

Yes, the 2SC4488T-AN is Pb-free and RoHS-compliant, as confirmed by onsemi's ordering information indicating "Pb Free" for all variants including 2SC4488T-AN in NMP(Taping) packaging. The device meets JEDEC J-STD-609 Category 1 marking requirements and is compatible with lead-free reflow profiles.

What is the maximum safe operating junction temperature for the 2SC4488T-AN?

The 2SC4488T-AN has a maximum junction temperature (T_j) rating of 150°C, with recommended operation below this limit under specified thermal conditions. At T_a = 25°C, its 1 W collector dissipation (P_C) derates linearly above 25°C at 8.3 mW/°C, reaching zero dissipation at 145°C ambient - requiring careful thermal design in enclosed or high-ambient environments.

Can the 2SC4488T-AN replace the 2SC4488S-AN in a design?

Yes, the 2SC4488T-AN can replace the 2SC4488S-AN in most designs, as both share identical package, pinout, absolute maximum ratings, and electrical characteristics - differing only in h_FE binning (T: 200–400 vs. S: 140–280). No layout or schematic changes are required, though circuit gain stability should be verified if operating near h_FE extremes.

What is the typical Cob value for the 2SC4488T-AN and how does it affect high-frequency performance?

The 2SC4488T-AN has a typical output capacitance (C_ob) of 8.5 pF at V_CB = –10 V and f = 1 MHz. This low capacitance minimizes Miller feedback in common-emitter amplifiers and reduces switching losses in high-frequency PWM applications, supporting clean edges up to ~100 MHz before parasitic roll-off dominates.
