Product details

Overview

2SC6044-TD-E from SANYO is an NPN epitaxial planar silicon transistor designed for high-current switching applications, with V_CEO = 30 V, I_C = 2 A continuous, V_CE(sat) = 260 mV at I_C = 1.5 A / I_B = 75 mA, and f_T = 400 MHz - used in voltage regulators, relay drivers, and lamp drivers.

For engineers reviewing the 2SC6044-TD-E datasheet, pinout, applications, or equivalent options, key selection criteria include low saturation voltage, high-speed switching (t_on = 40 ns, t_f = 30 ns), thermal performance on ceramic board, and MBIT process reliability in industrial control loads.

Technical Context

This transistor employs SANYO's MBIT (Modified Base Island Technology) process to achieve low V_CE(sat) and high current gain linearity across I_C = 100 mA to 1.5 A. Its f_T of 400 MHz supports fast digital and PWM switching up to several hundred kHz.

The device features a three-terminal TO-92MOD package with defined pinout (1: Base, 2: Collector, 3: Emitter), rated for T_j = 150°C and optimized for operation under pulsed conditions (I_CP = 5 A) and DC loads requiring stable gain (h_FE = 65–560).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	30 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration.
I_C (cont.)	2 A - Continuous collector current rating at T_c = 25°C, enabling direct drive of relays and lamps without external heat sinking.
V_CE(sat)	260 mV max at I_C = 1.5 A / I_B = 75 mA - Minimizes conduction loss and self-heating in high-duty-cycle switching.
f_T	400 MHz - Enables reliable operation in high-frequency switching power supplies and PWM motor control stages.
t_on/t_f	40 ns / 30 ns - Fast turn-on and fall times reduce switching losses and support >1 MHz pulse operation in optimized circuits.
h_FE	65–560 - Wide DC current gain range ensures robust biasing across temperature (–25°C to +75°C) and load current variation.
C_ob	12 pF at V_CB = 10 V - Low output capacitance preserves bandwidth and reduces Miller effect in high-speed amplifier or switch designs.

Pinout & Package

2SC6044-TD-E is housed in a TO-92MOD plastic package (SANYO PCP designation), with standardized lead formation and marking "HB" on the device body. The package is optimized for mounting on ceramic boards (450 mm² × 0.8 mm) to achieve 1.3 W power dissipation.

Pin/Terminal	Circuit Role	Design Meaning
1 (Base)	Control input terminal	Receives base current (max 400 mA) to saturate or cut off the transistor; requires current-limiting resistor in series for safe drive.
2 (Collector)	High-side switched output node	Carries full load current (up to 2 A DC); connected to positive supply rail in low-side switch configurations.
3 (Emitter)	Reference/return path	Common emitter connection; tied to ground or low-side return; establishes reference for V_BE and V_CE biasing.

Key Features

Feature	Design Value
MBIT process technology	Enables precise base doping profile for consistent h_FE, low V_CE(sat), and improved thermal stability over standard planar processes.
Low V_CE(sat)	260 mV max at rated current ensures <0.4 W conduction loss at 1.5 A, reducing heatsink requirements in compact regulators.
High-speed switching	40 ns turn-on and 30 ns fall time allow clean square-wave drive of inductive loads (relays, solenoids) with minimal ringing or cross-conduction risk.
High current capacity	2 A continuous / 5 A pulsed rating supports direct interface with 12 V automotive and industrial actuators without external driver stages.

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
2SC4116-TP	V_CEO = 20 V, I_C = 1.5 A, V_CE(sat) = 300 mV - lower voltage/current ratings and higher saturation drop.	Suitable only for ≤12 V, ≤1 A relay or LED loads; not recommended for 24 V regulators or 2 A lamps.	Select when cost sensitivity outweighs performance; verify PCB layout accommodates reduced thermal margin.
MJD127G	TO-220 package, V_CEO = 100 V, I_C = 2 A, V_CE(sat) = 1.5 V - higher voltage capability but significantly higher saturation loss.	Preferred for high-voltage industrial controls (e.g., 48–100 V DC systems); unsuitable for low-dropout linear regulators.	Choose only if system voltage exceeds 30 V or board space allows TO-220 footprint; avoid where thermal efficiency is critical.

Compared with 2SC6044-TD-E, 2SC4116-TP offers lower cost but sacrifices voltage headroom and efficiency, while MJD127G provides higher breakdown safety margin at the expense of conduction loss and board area - making 2SC6044-TD-E optimal for 12–24 V, 1–2 A switching where low V_CE(sat) and TO-92MOD fit are essential.

FAQ

What is the maximum continuous collector current rating for the 2SC6044-TD-E?

The 2SC6044-TD-E is rated for 2 A continuous collector current (I_C) at case temperature T_c = 25°C when mounted on a specified ceramic board (450 mm² × 0.8 mm). At ambient temperature (T_a = 25°C), derating applies per the PC–T_a curve, limiting usable current to approximately 1.3 A without forced cooling. This rating ensures safe operation in relay and lamp driver applications without additional heatsinking.

Does the 2SC6044-TD-E support high-frequency switching, and what is its gain-bandwidth product?

Yes, the 2SC6044-TD-E supports high-frequency switching with a guaranteed gain-bandwidth product (f_T) of 400 MHz at V_CE = 10 V and I_C = 300 mA. This enables stable operation in PWM-based lamp dimmers and switching regulators operating up to several hundred kHz. The 2SC6044-TD-E's low Cob (12 pF) and fast t_on/t_f further reinforce its suitability for clean, high-speed transitions.

What is the pin configuration of the 2SC6044-TD-E, and how is it identified physically?

The 2SC6044-TD-E uses a TO-92MOD package with pin 1 = Base, pin 2 = Collector, pin 3 = Emitter - verified in the official SANYO datasheet No.8251. The device is marked with "HB" on the package body, and lead orientation follows standard TO-92MOD viewing convention (flat side facing user, leads down). This pinout is critical for correct biasing in low-side switch configurations.

How does the MBIT process benefit the electrical performance of the 2SC6044-TD-E?

The MBIT (Modified Base Island Technology) process used in the 2SC6044-TD-E delivers tighter control of base region doping and geometry, resulting in lower V_CE(sat), improved h_FE consistency across current ranges, and enhanced thermal stability. In practice, this means the 2SC6044-TD-E maintains predictable gain from 100 mA to 1.5 A and sustains low saturation voltage even under elevated junction temperatures - directly improving efficiency in voltage regulators and lamp drivers.

Can the 2SC6044-TD-E be used in automotive applications?

The 2SC6044-TD-E is not qualified for automotive applications per AEC-Q101 or similar standards. While its operating temperature range (–55°C to +150°C) overlaps with some automotive ambient conditions, SANYO explicitly states that its products - including the 2SC6044-TD-E - are not intended for life-critical or high-reliability automotive systems such as engine control or braking. For automotive use, qualified alternatives with full PPAP documentation must be selected instead of the 2SC6044-TD-E.
