Product details
Overview
2SC4489T-AN from onsemi is an NPN bipolar junction transistor designed for high-voltage switching applications, featuring VCEO = 100 V, IC = 2 A, fT = 120 MHz, VCE(sat) = 0.13 V (typ) at IC = 1 A / IB = 100 mA, and SC-71 (NMP) surface-mount package. It serves as a fast-switching power switch in DC-DC converters and motor drivers.
For engineers reviewing the 2SC4489T-AN datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed hFE rank T (200–400), low saturation voltage under high-current drive, Pb-free taping packaging, and validated switching times (ton = 80 ns, tf = 40 ns).
Technical Context
The 2SC4489T-AN employs FBET and MBIT fabrication processes to achieve high breakdown voltage and low VCE(sat) simultaneously. Its fT of 120 MHz and Cob of 16 pF (typ) at VCB = –10 V support high-speed switching up to several tens of MHz in Class-A/B amplifiers and PWM circuits.
Rated for Tj = 150 °C and specified across –25 °C to +75 °C ambient, it delivers stable hFE and VCE(sat) performance over industrial temperature ranges. The device operates with IC/IB = 10 in switching mode and supports pulse currents up to 3 A (ICP).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 100 V - Enables use in 48 V bus and 100 V clamp circuits without derating. |
| IC | 2 A continuous - Supports medium-power load switching in industrial controls and power supplies. |
| fT | 120 MHz - Ensures reliable operation in high-frequency switching converters up to ~20 MHz practical switching frequency. |
| VCE(sat) | 0.13 V (typ) at IC = 1 A / IB = 100 mA - Reduces conduction loss and thermal stress in high-duty-cycle applications. |
| hFE Rank | T (200–400) - Guarantees consistent current gain for predictable base drive sizing in production designs. |
| tf | 40 ns - Limits switching transition losses and EMI generation during turn-off in hard-switched topologies. |
| PC | 1 W - Allows direct PCB mounting without heatsink in ≤0.5 W dissipation applications at Ta ≤ 75 °C. |
Pinout & Package
Package: SC-71 (JEITA/IEC standard), also designated NMP(Taping) by onsemi - 3-pin, ultra-thin, surface-mount plastic package with 0.6 mm max height and 2.54 mm lead pitch; optimized for automated pick-and-place and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter | Current exit node; connects to ground or low-side return path; requires low-inductance layout for fast switching. |
| 2 | Collector | High-voltage/current input node; ties to load or supply rail; must be routed with adequate creepage for 100 V operation. |
| 3 | Base | Control input; driven with ≥100 mA peak for full saturation; requires series resistor to limit drive current and prevent oscillation. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | 0.13 V typ at 1 A ensures <130 mW conduction loss, reducing thermal design burden in compact enclosures. |
| High fT | 120 MHz enables stable small-signal amplification and clean square-wave switching up to 20 MHz fundamental. |
| Rank-T hFE | 200–400 range eliminates need for binning or gain compensation in production base-drive circuits. |
| Fast fall time | 40 ns minimizes overlap loss in half-bridge configurations and improves efficiency in synchronous rectifier drivers. |
| Pb-free taping | NMP(Taping) format with 2500 pcs/bag supports automated SMT assembly and RoHS-compliant manufacturing. |
Applications
| Motor Drive Stage | DC-DC Converter Switch |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2SC4489S-AN | Same die, hFE rank S (140–280); otherwise identical absolute max ratings, switching specs, and package. | Suitable where lower gain tolerance is acceptable and cost optimization is prioritized over precise base drive predictability. | Select 2SC4489S-AN only if circuit tolerates wider hFE variation and base resistor can be adjusted accordingly. |
| MJD127G | TO-252 package, VCEO = 100 V, IC = 2 A, but fT = 3 MHz and VCE(sat) = 0.5 V (min) - significantly slower and higher loss. | Better thermal dissipation (1.5 W PC) but unsuitable for >100 kHz switching due to low fT and slow tf. | Choose MJD127G only for low-frequency, high-thermal-margin linear or quasi-square-wave applications where speed is not critical. |
Compared with 2SC4489S-AN, the 2SC4489T-AN offers tighter hFE control for robust base-drive design; versus MJD127G, it delivers superior high-frequency switching efficiency and lower conduction loss, albeit with lower power dissipation capability.

FAQ
What is the guaranteed hFE range for 2SC4489T-AN?
The 2SC4489T-AN is binned to Rank T, guaranteeing a DC current gain (hFE) between 200 and 400 when measured at VCE = –5 V and IC = –100 mA. This tight specification allows precise base resistor calculation without margining for gain spread, improving consistency in mass-produced 2SC4489T-AN-based switching circuits.
Is 2SC4489T-AN RoHS compliant and lead-free?
Yes, 2SC4489T-AN is RoHS compliant and Pb-free, as confirmed by its "-AN" suffix and explicit labeling in the onsemi datasheet (Ordering Information table). The NMP(Taping) packaging uses lead-free terminations and complies with JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for standard reflow profiles.
What is the maximum allowable collector current for continuous operation of 2SC4489T-AN?
The 2SC4489T-AN has a continuous collector current rating (IC) of 2 A at Ta = 25 °C. Derating is required above 25 °C ambient: the datasheet specifies a linear derating curve down to zero at 150 °C junction temperature. For reliable 2 A operation, board-level thermal design must maintain case temperature ≤ 75 °C.
Can 2SC4489T-AN replace 2SC4489S-AN in an existing design?
Yes, 2SC4489T-AN is a direct functional upgrade to 2SC4489S-AN - same package, pinout, voltage/current ratings, and switching characteristics - differing only in guaranteed hFE range (T: 200–400 vs. S: 140–280). No PCB or schematic changes are needed; improved gain consistency may allow reduction of base drive margin in the 2SC4489T-AN implementation.
What is the typical output capacitance (Cob) of 2SC4489T-AN and why does it matter?
The typical output capacitance (Cob) of 2SC4489T-AN is 16 pF at VCB = –10 V and f = 1 MHz. This parameter directly impacts switching speed and resonant behavior in hard-switched circuits; lower Cob reduces turn-on loss and eases gate driver design, making 2SC4489T-AN suitable for higher-frequency SMPS than devices with >30 pF Cob.
