Product details

Overview

2SC4107M-TON-ON from SANYO is an NPN triple diffused planar silicon transistor designed for high-voltage switching regulator applications, featuring 400 V V_CEO, 10 A I_C, 150 W P_C (T_C = 25 °C), and TO-220AB package. It delivers high-speed switching, wide active safe operating area (ASO), and MBIT process reliability in offline SMPS primary-side switch roles.

For engineers reviewing the 2SC4107M-TON-ON datasheet, pinout, applications, or equivalent options, key selection criteria include V_CEO ≥ 400 V, I_C ≥ 10 A DC, f_T = 20 MHz, V_CE(sat) ≤ 1.8 V at I_C/I_B = 5, and TO-220AB thermal performance under T_C-limited conditions.

Technical Context

This transistor operates as a high-voltage, medium-power NPN switch in flyback and forward converter primary circuits. Its design supports hard-switched topologies with V_CEO = 400 V, V_CBO = 500 V, and reverse-bias ASO rated up to 200 V with 100 µs pulse width.

It uses SANYO's MBIT (Modified Base Injection Technology) process to enhance ruggedness and switching consistency. Electrical behavior is characterized at T_C = 25 °C with pulsed conditions (PW ≤ 300 µs, duty cycle ≤ 10%), and specified h_FE ranges (L/M/N ranks) enable current gain binning for production matching.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	400 V - Maximum collector-emitter voltage before breakdown under open-base condition; defines primary-side voltage rating in offline SMPS.
I_C	10 A - Continuous DC collector current; sets maximum output power capability in non-pulsed operation.
P_C (T_C = 25 °C)	150 W - Maximum power dissipation at case temperature 25 °C; requires heatsink for sustained operation above ~25 W.
f_T	20 MHz - Transition frequency at V_CE = 10 V, I_C = 1.2 A; enables efficient switching up to ~100 kHz in practical converters.
V_CE(sat)	≤1.8 V @ I_C/I_B = 5 - Low saturation voltage reduces conduction loss and improves efficiency in hard-switched designs.
h_FE (Rank M)	40–100 @ V_CE = 5 V, I_C = 1.2 A - Mid-range DC current gain bin suitable for stable base drive design without excessive overdrive.
t_on/t_f	0.5 µs / 0.3 µs - Fast turn-on and fall times minimize switching loss during transitions at rated load.

Pinout & Package

SANYO TO-220AB package: insulated mounting flange, vertical lead orientation, 3-pin through-hole configuration with standard 2.54 mm pitch. Mounting hole centered on flange for mechanical stability and thermal interface.

Pin/Terminal	Circuit Role	Design Meaning
1 (Base)	Control input terminal	Receives base current to bias transistor into saturation or cutoff; requires external resistor network for proper drive level and speed.
2 (Collector)	High-voltage power input	Connected to primary winding of transformer and bulk DC bus; carries full switching current and withstands 400 V transient stress.
3 (Emitter)	Power return path	Common reference for base drive and current sensing; tied to source of control IC or shunt resistor in grounded-emitter topology.

Key Features

Feature	Design Value
High breakdown voltage	V_CBO = 500 V ensures margin against voltage spikes in 230 VAC-input SMPS with leakage inductance ringing.
Wide active safe operating area (ASO)	Forward-bias ASO extends to 200 V/10 A with 100 µs pulse width, enabling robust single-pulse surge handling.
High-speed switching	t_on = 0.5 µs and t_f = 0.3 µs reduce energy loss per switching cycle in 50–100 kHz converters.
MBIT process technology	Improves secondary breakdown immunity and gain uniformity across production lots for consistent BOM yield.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SC4027M-TON-ON	V_CEO = 400 V, I_C = 7 A, P_C = 100 W - lower current/power rating and narrower ASO.	Suitable only for ≤50 W designs; insufficient for 2SC4107M-TON-ON's 10 A/150 W envelope.	Select when board space or cost constraints preclude TO-220AB derating; verify thermal margin at full load.
MJD122G	V_CEO = 100 V, I_C = 8 A, TO-220F package - incompatible voltage rating for offline use.	Restricted to low-voltage DC-DC converters (e.g., 12–48 V input); not usable in AC-DC primary side.	Only consider in isolated low-voltage systems where 400 V capability is unnecessary; no direct replacement.

Compared with 2SC4107M-TON-ON, 2SC4027M-TON-ON offers reduced power handling but identical voltage class and footprint, while MJD122G lacks required breakdown voltage entirely-making both alternatives unsuitable as drop-in replacements but viable for de-rated or low-voltage redesigns.

FAQ

What is the maximum junction temperature specification for the 2SC4107M-TON-ON?

The 2SC4107M-TON-ON has a maximum junction temperature (T_j) of 150 °C, as defined in its Absolute Maximum Ratings table. This limit must not be exceeded during operation, and thermal design must ensure that actual T_j remains below this value under worst-case ambient and power dissipation conditions. Derating curves in the datasheet show allowable power dissipation versus case temperature.

Does the 2SC4107M-TON-ON have a built-in base-emitter resistor or protection diode?

No, the 2SC4107M-TON-ON is a standard three-terminal NPN bipolar transistor without integrated base resistors or protection diodes. External base drive circuitry-including current-limiting resistors and optional clamping diodes-must be provided per application requirements. Its pinout (Base, Collector, Emitter) reflects this discrete, unassisted structure.

Is the 2SC4107M-TON-ON RoHS compliant?

The 2SC4107M-TON-ON was manufactured prior to full RoHS enforcement and does not carry official RoHS certification. Its datasheet (dated July 2004) predates EU RoHS Directive 2002/95/EC compliance deadlines. For new designs requiring RoHS compliance, consult Aetrix Electronics for qualified drop-in alternatives or re-engineered equivalents.

What is the typical h_FE range for the 2SC4107M-TON-ON at I_C = 6 A?

At I_C = 6 A and V_CE = 5 V, the 2SC4107M-TON-ON exhibits h_FE = 80–100 for Rank N, 40–100 for Rank M, and 30–50 for Rank L. The Rank M variant-most commonly stocked-is specified at h_FE = 40–100 under those conditions, supporting predictable base drive sizing across production batches.

Can the 2SC4107M-TON-ON be used in avalanche mode?

No, the 2SC4107M-TON-ON is not rated or characterized for repetitive avalanche operation. Its Safe Operating Area (ASO) charts cover forward- and reverse-bias conditions under pulsed operation, but no avalanche energy (E_AS) rating or ruggedness test data is provided in the official SANYO documentation. Designers must avoid operation beyond V_CBO or V_CEO limits.
