Product details

Overview

2SA2169-E from onsemi is a PNP bipolar junction transistor rated for −50 V V_CEO, −10 A I_C, and low −290 mV typical V_CE(sat) at −5 A/−250 mA, optimized for high-current switching in relay, lamp, and motor driver circuits.

For engineers reviewing the 2SA2169-E datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (TP), terminal roles, saturation voltage behavior, switching timing (t_on = 40 ns typ), and direct alternatives with documented parameter divergence.

Technical Context

This PNP transistor uses onsemi's MBIT process to achieve high current handling (−10 A continuous, −13 A pulsed) and low saturation voltage while maintaining f_T = 200 MHz typical for moderate-speed switching. Its SC-64 (TO-251) TP package supports surface-mount thermal management up to 20 W at T_c = 25°C.

Electrical characteristics are specified at T_a = 25°C with validated min/typ/max values across h_FE (200–700), V_(BR)CEO (−50 V), and Cob (60 pF typ at V_CB = −10 V), enabling reliable design in DC-coupled load-switching topologies without external bias compensation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−50 V - Maximum safe collector-emitter voltage under open-base conditions; defines blocking capability in high-side switch configurations.
I_C	−10 A - Continuous collector current rating; supports sustained 10 A load switching without derating at T_c ≤ 25°C.
V_CE(sat)	−290 mV typ at I_C = −5 A, I_B = −250 mA - Low conduction loss enables <1.5 W power dissipation in saturated switching mode.
f_T	200 MHz typ at V_CE = −5 V, I_C = −1 A - Sufficient bandwidth for PWM frequencies up to ~10 MHz with controlled rise/fall times.
t_on/t_f	40 ns / 80 ns typ - Fast turn-on and fall enable efficient operation in 100 kHz–1 MHz switching applications.
h_FE	560 typ at V_CE = −2 V, I_C = −1 A - High DC gain reduces required base drive current and simplifies gate-driver interface design.
C_ob	60 pF typ at V_CB = −10 V - Low output capacitance minimizes switching energy loss and improves high-frequency efficiency.

Pinout & Package

2SA2169-E is supplied in the TP package (JEITA SC-64 / JEDEC TO-251), a 4-pin surface-mount variant with dual collector terminals for enhanced current sharing and thermal path optimization. The package has a mass of 0.315 g and footprint dimensions of 7.0 × 5.0 × 2.3 mm (L × W × H).

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input node requiring −250 mA peak base current to saturate at −5 A collector current.
2	Collector	Main high-current output terminal; electrically identical to Pin 4 for parallel current routing and thermal spreading.
3	Emitter	Reference node tied to system ground or positive rail in high-side PNP configuration; carries full load current.
4	Collector	Second collector terminal-bond-wire redundant path to reduce effective R_DS(on)-equivalent resistance and improve thermal reliability.

Key Features

Feature	Design Value

Dual-collector terminal layout	Provides 2× current-handling margin and lowers thermal resistance via parallel metal paths in the TP package.
High h_FE consistency	200–700 range at I_C = −1 A ensures stable base drive design across production lots without feedback trimming.
Fast switching performance	40 ns t_on and 80 ns t_f support clean edge integrity in 500 kHz PWM motor control without snubber networks.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP high-current switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD2955RLG	V_CEO = −60 V, I_C = −10 A, V_CE(sat) = −1.2 V max at −5 A - higher saturation voltage, lower f_T (3 MHz).	Less suitable for high-efficiency PWM drivers; better for linear-regulator pass devices or slow-switching logic interfaces.	Select when higher breakdown margin is critical and switching speed is secondary.
SS8550DTA	V_CEO = −25 V, I_C = −1.5 A, V_CE(sat) = −400 mV typ - lower voltage/current ratings, TO-92 package.	Only appropriate for sub-1 A loads; incompatible with 2SA2169-E's thermal and current demands.	Choose only for space-constrained prototyping where full 2SA2169-E capability is unnecessary.

Compared with MJD2955RLG and SS8550DTA, the 2SA2169-E delivers superior switching efficiency (−290 mV vs. −1.2 V/−400 mV), higher frequency response (200 MHz vs. 3 MHz/<100 MHz), and surface-mount thermal scalability (TP vs. TO-220/TO-92), making it optimal for production-grade motor and relay drivers.

FAQ

What is the maximum continuous collector current rating for the 2SA2169-E?

The 2SA2169-E is rated for −10 A continuous collector current (I_C) at case temperature T_c = 25°C. Derating applies above 25°C per the PC–Tc curve in the datasheet; at T_c = 100°C, the usable I_C drops to approximately −5.5 A. This rating assumes proper PCB copper area and thermal vias per the land pattern example in the 2SA2169-E datasheet.

Does the 2SA2169-E have pin-to-pin compatibility with the 2SC6017-E?

No, the 2SA2169-E (PNP) and 2SC6017-E (NPN) are complementary devices in the same family but have opposite polarity and non-interchangeable pin functions. While both use the TP package and share identical mechanical pinout (Base–Collector–Emitter–Collector), their electrical roles differ: Pin 1 is Base for both, but Pin 2/4 serve as Collector for 2SA2169-E and Emitter for 2SC6017-E. Direct substitution would invert circuit operation.

What is the typical collector-to-emitter saturation voltage of the 2SA2169-E at rated current?

The 2SA2169-E exhibits a typical V_CE(sat) of −290 mV at I_C = −5 A and I_B = −250 mA, with a maximum of −580 mV under the same conditions. This low saturation voltage directly reduces conduction losses to <1.5 W at full rated current, supporting thermally constrained PCB layouts without forced air or heatsinks.

Can the 2SA2169-E be used in high-frequency switching applications above 1 MHz?

The 2SA2169-E has a typical f_T of 200 MHz and measured t_on/t_f of 40 ns/80 ns, supporting clean switching up to ~5 MHz in optimized gate-drive circuits. However, its storage time (t_stg = 1000 ns max) limits hard-switching efficiency above 1 MHz; for >1 MHz operation, active base-drive control (e.g., Baker clamp or negative turn-off) is recommended to mitigate minority-carrier delay.

What package variants are available for the 2SA2169-E, and how do they differ?

The 2SA2169-E is offered in the TP (TO-251/SC-64) package in bag format (500 pcs./bag), while the 2SA2169-TL-E uses the TP-FA (TO-252/SC-63) variant in tape-and-reel (700 pcs./reel). Both share identical electrical specs and pin numbering, but TP-FA has a larger exposed pad and different leadframe geometry for improved thermal transfer in high-power density layouts.
