Microchip Technology 2N5416

Overview

2N5416 from STMicroelectronics is a high-voltage silicon epitaxial planar PNP transistor in TO-39 metal package, rated for V_CBO = −350 V, V_CEO = −300 V, I_C = −1 A, and P_tot = 10 W at T_c ≤ 25°C. It serves as a switching or series regulator driver in line-operated industrial inverters and high-voltage power supplies.

For engineers reviewing the 2N5416 datasheet, 2N5416 pinout, 2N5416 application, or 2N5416 equivalent, key selection criteria include sustained collector-emitter voltage (V_CE(sus) = −350 V), low leakage (I_CBO ≤ −50 µA at V_CB = −280 V), DC current gain (h_FE = 30–120), saturation behavior (V_CE(sat) = −2.5 V @ I_C = −50 mA, I_B = −5 mA), and thermal resistance (R_thj-case = 17.5°C/W).

Technical Context

This PNP bipolar junction transistor uses an epitaxial planar structure to achieve high breakdown voltage and stable leakage performance under high reverse bias. Its rugged TO-39 metal case enables direct heatsinking and supports pulsed operation up to 300 µs with 1.5% duty cycle.

The device operates with base-emitter forward bias (V_BE = −1.5 V @ I_C = −50 mA) and exhibits f_T = 15 MHz, supporting medium-speed switching in regulated DC-DC stages and inverter gate drive interfaces where high off-state blocking is critical.

FAQ

Is the 2N5416 pin-compatible with the 2N5415?

Yes - both share identical TO-39 pinout (Emitter, Base, Collector in clockwise order when viewed from top with tab at 6 o'clock) and mechanical dimensions. However, the 2N5416 has higher voltage ratings (V_CBO = −350 V vs. −200 V; V_CEO = −300 V vs. −200 V), making it a direct upgrade where enhanced blocking is needed.

Can the 2N5416 be used in avalanche mode?

No - the datasheet does not specify or characterize avalanche energy capability. Its V_CE(sus) rating applies only under pulsed conditions with defined duty cycle (1.5%) and pulse width (300 µs); sustained avalanche operation is not supported and may cause irreversible degradation.

What is the maximum safe operating temperature for continuous use?

The junction temperature must not exceed 200°C, and case temperature must remain ≤25°C to sustain full 10 W dissipation. At ambient ≤50°C with no heatsink, derated power drops to 1 W - thermal design must ensure R_thj-amb ≤ 150°C/W for safe continuous operation.

Does the metal case require electrical isolation from the heatsink?

Yes - the collector is internally bonded to the TO-39 metal case. If the heatsink is grounded or at a different potential, insulating hardware (mica washer + shoulder washer) and dielectric thermal paste must be used to prevent short circuits and ensure safe operation.
