onsemi 2SC5763M

Overview

2SC5763M from SANYO is an NPN triple diffused planar silicon transistor designed for high-voltage switching regulator applications. It features V_CEO = 400 V, V_CBO = 700 V, I_C = 7 A continuous, P_C = 55 W at T_c = 25°C, and f_T = 17 MHz - enabling robust primary-side switching in offline SMPS designs.

For engineers reviewing the 2SC5763M datasheet, pinout, applications, or equivalent options, key selection criteria include its wide Active Safe Operating Area (ASO), MBIT process reliability, 0.5 µs turn-on time, and TO-220 package thermal performance in high-dV/dt flyback and forward converter topologies.

Technical Context

This device operates as a high-voltage, medium-power NPN bipolar junction transistor optimized for hard-switched DC-DC conversion. Its design emphasizes ruggedness under repetitive avalanche stress, with V_(BR)CEO = 400 V and wide reverse-bias ASO confirmed per Figure IT03060.

The MBIT (Modified Base Injection Technology) process enhances switching speed and gain uniformity across current ranges: h_FE1 = 20–40 (rank M), h_FE2 = 10 at I_C = 4 A, and V_CE(sat) = 0.8 V at I_C = 4 A / I_B = 0.8 A - supporting stable base drive in fixed-frequency PWM controllers.

Key Specifications

Pinout & Package

2SC5763M is housed in a standard TO-220 package (SANYO designation: TA-3501/TA-3234), with mounting tab electrically connected to the collector. The case outline matches JEDEC TO-220AB mechanical dimensions, including 15.1 mm height and 10.2 mm width.

2SC5763M is available at Aetrix Electronics and suitable for offline switching regulators, industrial AC-DC power supplies, and high-voltage DC-DC boost converters requiring stable component supply and long-lifecycle support.

Supply support for 2SC5763M includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

SANYO Electric Co., Ltd. was a Japanese semiconductor manufacturer known for high-reliability power transistors and analog ICs before its acquisition by Panasonic in 2012.

The 2SC5763M belongs to SANYO's high-voltage BJT family engineered specifically for ruggedized switching regulator primary-side operation - emphasizing ASO integrity, thermal stability, and MBIT process consistency in industrial power conversion.

FAQ

What is the h_FE range for the 2SC5763M transistor?

The 2SC5763M has h_FE1 = 20–40 at V_CE = 5 V and I_C = 0.8 A (rank M specification). Its h_FE2 drops to minimum 10 at I_C = 4 A, confirming usable gain under high-current saturation conditions required in SMPS designs. This rank-specific gain band ensures predictable base drive sizing for the 2SC5763M across production lots.

Does the 2SC5763M have avalanche capability?

The 2SC5763M is not explicitly rated for repetitive avalanche operation. While its wide reverse-bias ASO (per Figure IT03060) provides margin against single-event overvoltage, SANYO documentation does not specify E_AS or guaranteed non-destructive avalanche energy. For designs subject to frequent inductive turn-off stress, external clamping remains recommended for the 2SC5763M.

What is the maximum allowable case temperature for continuous operation of the 2SC5763M?

The 2SC5763M has a maximum junction temperature (T_j) of 150°C. With a TO-220 package thermal resistance (R_θJC) of approximately 1.2°C/W, the maximum case temperature depends on power dissipation: at P_C = 55 W (rated max), T_c must remain ≤25°C. For practical continuous operation, T_c should be limited to ≤80°C to maintain safe T_j margin - requiring appropriate heatsinking for the 2SC5763M.

Can the 2SC5763M replace the 2SC5763 without changes to the PCB layout?

Yes - the 2SC5763M shares identical TO-220 package dimensions, pinout (Base–Collector–Emitter), and mechanical footprint with the base 2SC5763. The "M" suffix denotes h_FE rank only (20–40), with no electrical or mechanical differentiation. PCB layout, soldering profile, and thermal interface for the 2SC5763M remain fully compatible with the original 2SC5763.

Is the 2SC5763M suitable for use in automotive power supplies?

No - SANYO explicitly states that the 2SC5763M is not qualified for applications requiring extremely high reliability, such as automotive control systems or life-support equipment. Its specifications reflect industrial-grade performance, and it lacks AEC-Q101 qualification, extended temperature screening, or failure-in-time (FIT) data required for automotive deployment. Use in automotive environments is not recommended for the 2SC5763M.
