Product details

Overview

2SA1552S-N-TL-E from onsemi is a PNP bipolar junction transistor rated for –160 V V_CEO, –1.5 A continuous collector current, and ultra-high-speed switching (f_T = 120 MHz), with low V_CE(sat) of –0.13 V at –500 mA/–50 mA drive. It serves as a high-voltage, high-current switching element in color TV audio output stages and DC-DC converter power switches.

For engineers reviewing the 2SA1552S-N-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include verified PNP polarity, TP-FA package compatibility with SC-63/TO-252 footprint, –180 V V_CBO rating, 120 MHz f_T, and –0.13 V typical V_CE(sat) under specified bias conditions.

Technical Context

This device employs FBET and MBIT fabrication processes to achieve high-voltage blocking (–180 V V_CBO) and large-current capability (–1.5 A I_C) while maintaining ultrahigh-speed switching performance (t_on = 60 ns, t_f = 50 ns). Its low saturation voltage (–0.13 V typ. at –500 mA/–50 mA) minimizes conduction loss in hard-switched topologies.

The 2SA1552S-N-TL-E is designed for complementary use with the NPN 2SC4027 in push-pull configurations. Its TP-FA package features dual collector terminals (pins 2 and 4), enabling low-inductance high-current paths and thermal relief via exposed drain pad - critical for converters and inverters operating at elevated ambient temperatures.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	–160 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration; defines usable voltage headroom in high-side switch applications.
I_C	–1.5 A - Continuous DC collector current rating at T_a = 25°C; sets steady-state power stage current capacity without derating.
f_T	120 MHz - Gain-bandwidth product at V_CE = –10 V, I_C = –50 mA; enables reliable operation up to ~10–20 MHz switching frequencies in Class D or SMPS designs.
V_CE(sat)	–0.13 V (typ.) at I_C = –500 mA, I_B = –50 mA - Low saturation voltage reduces conduction loss and self-heating during active switching.
t_on/t_f	60 ns / 50 ns - Verified turn-on and fall times under standardized test circuit; supports >5 MHz hard-switching in optimized layouts.
C_ob	12 pF (typ.) at V_CB = –10 V - Output capacitance impacts switching loss and EMI in high-dV/dt applications; value confirmed at 1 MHz.

Pinout & Package

2SA1552S-N-TL-E uses the TP-FA surface-mount package (JEITA/ JEDEC: SC-63, TO-252), featuring an exposed thermal pad and dual collector terminals for enhanced current handling and thermal dissipation. The package measures 7.0 × 5.0 × 2.3 mm (L × W × H) with 0.282 g mass.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input node; requires –50 mA base drive for full saturation at –500 mA collector current.
2	Collector	Primary high-current output terminal; electrically tied to pin 4; connects to high-side rail or transformer primary.
3	Emitter	Common reference node for PNP operation; typically tied to system ground or positive supply rail in high-side switch topology.
4	Collector	Secondary collector terminal; paralleled with pin 2 to reduce bondwire inductance and improve current sharing in high-frequency switching.

Key Features

Feature	Design Value
Ultrahigh-speed switching	60 ns turn-on time and 50 ns fall time enable efficient operation in >5 MHz DC-DC converters and Class D audio amplifiers.
Low V_CE(sat)	–0.13 V typical at –500 mA/–50 mA ensures <130 mW conduction loss per device, reducing thermal stress in compact layouts.
Dual collector terminals	Pins 2 and 4 provide parallel current paths and lower effective package inductance, critical for minimizing voltage overshoot in fast-switching circuits.
FBET/MBIT process technology	Enables simultaneous optimization of breakdown voltage (–180 V V_CBO), current gain (h_FE = 140–400), and switching speed (120 MHz f_T).

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SA1552S-TL-E	Same die, identical electrical specs, same TP-FA package; differs only in h_FE rank (S: 140–280 vs. N: not explicitly ranked in source but implied standard grade).	No functional difference; both qualified for color TV, converter, and inverter use per shared datasheet.	Select 2SA1552S-N-TL-E when standard h_FE binning suffices; choose S-grade if tighter h_FE consistency required across production lots.
MJD2955G	–70 V V_CEO, –10 A I_C, TO-252 package; higher current but lower voltage rating; f_T not specified in datasheet.	Suitable for lower-voltage industrial motor drives but unsuitable for 160 V+ bus applications like color TV or high-input converters.	Use MJD2955G only where bus voltage ≤70 V and peak current >1.5 A is needed; 2SA1552S-N-TL-E remains preferred for ≥100 V systems.

Compared with 2SA1552S-TL-E, the 2SA1552S-N-TL-E offers identical performance with relaxed h_FE binning, lowering cost without compromising switching or voltage capability; versus MJD2955G, it trades current capacity for essential high-voltage robustness, making it the only viable option for 160 V-class designs.
