Product details

Overview

2SA1593S-TL-E from onsemi is a PNP bipolar junction transistor in TP-FA (TO-252) package, rated for −100 V V_CEO, −2 A I_C, and low −0.22 V typical V_CE(sat) at −1 A/−100 mA drive, used in relay drivers and compact power supply output stages.

For engineers reviewing the 2SA1593S-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include verified PNP switching performance, TO-252 thermal dissipation capability (15 W at T_c = 25°C), and rank-S h_FE range (100–200) under −5 V V_CE.

Technical Context

This device is a discrete PNP BJT fabricated using FBET and MBIT processes, delivering high breakdown voltage (−120 V V_CBO) and fast switching with t_on = 80 ns, t_stg = 750 ns, and t_f = 40 ns under specified test conditions. It operates with guaranteed h_FE ≥ 100 at −5 V V_CE, −100 mA I_C.

The 2SA1593S-TL-E shares identical electrical specs and package footprint with its companion NPN 2SC4135S-TL-E, enabling complementary pair use in push-pull and H-bridge configurations without layout redesign.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−100 V - supports high-side switching in 48 V and 100 V DC bus applications
I_C	−2 A continuous - drives relays, solenoids, and lamp loads up to 24 W at 12 V
V_CE(sat)	−0.22 V typ @ −1 A/−100 mA - reduces conduction loss and self-heating in linear and saturated switch modes
f_T	120 MHz - enables stable operation in PWM frequencies up to 500 kHz with margin
h_FE	100–200 (Rank S) @ −5 V V_CE, −100 mA I_C - ensures predictable base drive sizing for reliable saturation
C_ob	16 pF @ −10 V V_CB - limits Miller feedback in high-speed switching nodes
P_C (T_c=25°C)	15 W - allows direct mounting to PCB copper pour or small heatsink for thermal management

Pinout & Package

Package: TP-FA (JEDEC TO-252, JEITA SC-63), surface-mount, 4-pin configuration with dual collector terminals for enhanced current handling and thermal path.

Pin/Terminal	Circuit Role	Design Meaning

4	Collector	Second collector terminal - paralleled with Pin 2 to reduce bond wire resistance and improve thermal spreading

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP bipolar switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD2955RLG	TO-220 package, −60 V V_CEO, −10 A I_C, higher V_CE(sat) (−1.2 V min)	Requires heatsink for >1 A; unsuitable for 100 V bus; better for high-current, low-voltage linear regulation	Select when higher current capacity is needed and board space allows TO-220 mounting
2SA1020-Y	TO-220F package, −120 V V_CEO, −3 A I_C, slower switching (t_f = 150 ns), no dual collector	Higher power dissipation but larger footprint; lacks fast edge control for PWM dimming	Choose for cost-sensitive 100 V relay drivers where switching speed is secondary

Compared with MJD2955RLG and 2SA1020-Y, the 2SA1593S-TL-E offers superior combination of high-voltage rating, low saturation voltage, and surface-mount TO-252 packaging-making it optimal for compact, high-efficiency 48–100 V DC switching where thermal and layout constraints are critical.

FAQ

What is the maximum continuous collector current rating for the 2SA1593S-TL-E?

The 2SA1593S-TL-E has a maximum continuous collector current I_C of −2 A at T_c = 25°C. This rating assumes proper PCB copper area or heatsinking; derating applies above 25°C case temperature per the PC–Ta curve in the datasheet. The 2SA1593S-TL-E maintains safe operation up to −1.5 A at 85°C case temperature with adequate thermal design.

Is the 2SA1593S-TL-E pin-compatible with the 2SA1593S-E?

Yes, the 2SA1593S-TL-E and 2SA1593S-E share identical pinout (Base–Collector–Emitter–Collector) and mechanical outline, but differ in packaging: 2SA1593S-TL-E uses TP-FA (TO-252) tape-and-reel (700 pcs./reel), while 2SA1593S-E uses TP (TO-251) bag packing (500 pcs./bag). Both are functionally and electrically identical.

What does the 'S' suffix indicate in 2SA1593S-TL-E?

The 'S' in 2SA1593S-TL-E denotes h_FE Rank S, specifying a DC current gain range of 100–200 at −5 V V_CE and −100 mA I_C. This binning ensures predictable base drive requirements and consistent switching behavior across production lots of the 2SA1593S-TL-E.

Can the 2SA1593S-TL-E be used in complementary pair with the 2SC4135S-TL-E?

Yes, the 2SA1593S-TL-E is explicitly designed as the PNP complement to the NPN 2SC4135S-TL-E. Both share identical TP-FA packaging, thermal characteristics, and matched electrical parameters (e.g., f_T, V_CE(sat), t_f), enabling balanced push-pull and Class-B amplifier topologies without layout modification.

What is the thermal resistance (R_θJC) of the 2SA1593S-TL-E?

The 2SA1593S-TL-E has a junction-to-case thermal resistance R_θJC of 1.7°C/W, measured from junction to the center tab (collector pad). This value is derived from the 15 W P_C rating at T_c = 25°C and confirms efficient heat transfer through the dual-collector TP-FA package structure of the 2SA1593S-TL-E.
