Product details

Overview

2SC5775 from SANYO is an NPN triple diffused planar silicon power transistor rated for 160 V V_CEO, 12 A continuous collector current, and 130 W collector dissipation at T_c = 25°C. It features high ASO (Area Safe Operating), robust breakdown durability, and MBIT process technology-designed for high-current switching in audio output stages and industrial motor drivers.

For engineers reviewing the 2SC5775 datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CEO/I_C ratings, TO-3PB package thermal performance, h_FE stability across 1–6 A, V_CE(sat) ≤ 2.0 V at I_C = –6 A, and switching times (t_on, t_stg, t_f) validated under defined test conditions.

Technical Context

The 2SC5775 operates as a high-voltage, high-current NPN switching transistor with DC current gain (h_FE) of 60–160 at I_C = –1 A and 35 min at I_C = –6 A. Its f_T is 15 MHz (typ), supporting audio-frequency switching and linear amplification up to ~100 kHz.

Designed for ruggedized operation, it delivers V_CE(sat) = –0.3 V (min) / –2.0 V (max) at I_C = –6 A and I_B = –0.6 A, with turn-on time of 0.56 µs, storage time of 3.3 µs, and fall time of 0.4 µs-measured using the specified RL = 8.33 Ω, V_CC = 50 V test circuit.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	160 V - Maximum safe collector-emitter voltage before avalanche breakdown under open-base condition.
I_C (continuous)	12 A - Continuous collector current rating at T_c = 25°C; derates above case temperature.
P_C (T_c=25°C)	130 W - Maximum power dissipation with case held at 25°C; requires heatsink for sustained operation.
h_FE @ I_C=–6 A	35 (min) - Minimum DC current gain at high-current switching point; ensures reliable base drive sizing.
V_CE(sat) @ I_C/I_B=–6 A/–0.6 A	–0.3 to –2.0 V - Saturation voltage range defining conduction loss and thermal stress in switching mode.
t_on/t_stg/t_f	0.56 / 3.3 / 0.4 µs - Verified switching timing values under standardized 50 V, 8.33 Ω load test circuit.

Pinout & Package

2SC5775 is housed in a TO-3PB metal package with isolated collector tab, optimized for high-power thermal management and mechanical mounting. Pin 1 = Base, Pin 2 = Collector (tab), Pin 3 = Emitter.

Pin/Terminal	Circuit Role	Design Meaning
1 (Base)	Control input terminal	Receives base current to bias transistor into active/saturation; requires current-limiting resistor in driver stage.
2 (Collector)	Main power output terminal	Connected to heatsink via isolated metal tab; carries full load current and dissipates majority of heat.
3 (Emitter)	Power return/reference terminal	Serves as common emitter node; often tied to ground or low-side switch reference in Class AB/B amplifier outputs.

Key Features

Feature	Design Value
High ASO capability	Enables safe operation under transient overvoltage and overcurrent without secondary breakdown-critical for audio output protection.
MBIT process technology	Improves carrier mobility and thermal stability, yielding consistent h_FE and reduced parameter drift across temperature.
TO-3PB package with isolated collector	Allows direct heatsink mounting without insulating washer while maintaining electrical isolation between collector and chassis.
Wide safe operating area (SOA)	Validated up to 10 ms pulse at I_CP = 24 A and V_CE = 160 V-supports surge-tolerant motor control and amplifier peak loads.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SC5200	V_CEO = 230 V, I_C = 15 A, P_C = 150 W, TO-3P package; higher voltage/current but larger footprint.	Better suited for >200 V bus applications; less optimal for space-constrained 160 V designs where 2SC5775's TO-3PB offers tighter thermal path.	Select 2SC5200 when higher voltage margin or greater power headroom is required; verify PCB pad layout compatibility.
MJE13009	V_CEO = 400 V, I_C = 12 A, P_C = 100 W, TO-218 package; higher V_CEO but lower power dissipation and different pinout.	Preferred in universal-input SMPS where 400 V rating is mandatory; not drop-in due to non-isolated collector and distinct pin assignment.	Choose MJE13009 for 380–400 V DC link applications; avoid direct substitution without thermal and layout revalidation.

Compared with 2SC5200 and MJE13009, the 2SC5775 provides optimal balance of 160 V rating, 130 W thermal capability in TO-3PB, and proven ASO performance for audio and mid-voltage industrial switching-making it preferred where board space, heatsink interface, and SOA integrity are prioritized over maximum voltage headroom.

FAQ

What is the maximum junction temperature rating for the 2SC5775?

The 2SC5775 has a maximum junction temperature (T_j) rating of 150°C, as specified in its Absolute Maximum Ratings table. This limit must not be exceeded during operation-even momentarily-to ensure reliability and prevent thermal runaway. Derating curves in the datasheet show allowable collector dissipation versus case temperature, and proper heatsinking is essential to maintain T_j ≤ 150°C under full-load conditions.

Is the 2SC5775 pin-compatible with the 2SC5200?

No, the 2SC5775 is not pin-compatible with the 2SC5200. While both use metal packages, the 2SC5775 uses TO-3PB (with isolated collector tab and pin order Base–Collector–Emitter), whereas the 2SC5200 uses TO-3P (non-isolated collector, pin order Emitter–Base–Collector). Mechanical and electrical mounting differences require PCB redesign for substitution.

What does "MBIT process" mean for the 2SC5775?

MBIT (Multi-Base Integrated Technology) is SANYO's proprietary fabrication process for power transistors that enhances carrier transport efficiency and thermal uniformity across the die. For the 2SC5775, MBIT contributes to stable h_FE across current and temperature, improved secondary breakdown immunity, and consistent V_CE(sat) behavior-key for high-fidelity audio and industrial switching reliability.

Can the 2SC5775 be used in complementary pairs with the 2SA2063?

Yes, the 2SC5775 is explicitly designed as the NPN complement to the PNP 2SA2063, sharing identical package (TO-3PB), voltage/current ratings (160 V/12 A), thermal characteristics, and SOA curves. Their matched parameters enable symmetrical Class AB amplifier output stages and balanced half-bridge configurations without gain or timing skew.

What is the typical Cob (output capacitance) value for the 2SC5775?

The typical output capacitance (C_ob) of the 2SC5775 is 170 pF, measured at V_CB = –10 V and f = 1 MHz. This value impacts high-frequency switching losses and resonant behavior in RF or ultrasonic driver circuits; the datasheet also lists a maximum of 340 pF, which should be used for worst-case EMI and snubber design.
