Product details

Overview

2SD1193 from SANYO is an NPN epitaxial planar silicon Darlington transistor designed for high-current switching in driver applications, with V_CEO = −60 V, I_C = −15 A, P_C = 7 W at T_c = 25 °C, and h_FE ≥ 2000 at I_C = −7 A, used in relay drivers, printer hammer drivers, and motor control circuits.

For engineers reviewing the 2SD1193 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical ratings, TO-3PB package mapping, saturation voltage behavior under I_C/I_B = 500, ASO curves for pulsed operation, and validated alternative transistors for industrial driver designs.

Technical Context

The 2SD1193 operates as a two-stage monolithic NPN Darlington pair with integrated base-emitter resistor (200 Ω), enabling direct TTL/CMOS logic-level drive without external biasing. Its design targets high DC current gain (h_FE up to 10,000) and low V_CE(sat) ≤ −1.5 V at I_C = −7 A, I_B = −14 mA.

It features wide Safe Operating Area (ASO) supporting 20 A peak collector current (I_CP) in 1 ms pulses and continuous 15 A operation at T_c ≤ 25 °C. Thermal derating follows a linear PC–Tc curve down to 0 W at 160 °C case temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V - Maximum collector-emitter voltage before breakdown under open-base condition; defines upper rail limit in high-voltage switching.
I_C (DC)	−15 A - Continuous collector current rating at T_c = 25 °C; supports sustained load driving without forced cooling.
P_C	7 W - Collector power dissipation at T_c = 25 °C; requires heatsinking above ~2.5 W in typical PCB-mount use.
h_FE	2000–10000 - DC current gain range at V_CE = −2 V, I_C = −7 A; enables microampere-level base drive for ampere-level loads.
V_CE(sat)	−1.5 V max at I_C/I_B = 500 - Low saturation voltage reduces conduction loss and heat generation in on-state switching.
f_T	2 MHz - Transition frequency at V_CE = −5 V, I_C = −7 A; suitable for <100 kHz switching but not RF or fast PWM.

Pinout & Package

SANYO TO-3PB metal package: isolated collector tab, 3-pin through-hole configuration with 1.2 mm lead diameter, 20.0 × 15.0 mm footprint, and 4.8 mm height. Mounting hole centered on collector tab.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Input control terminal; internally connected to 200 Ω resistor to emitter; accepts logic-level drive (≤5 V).
2	Collector	Main current output node; electrically tied to metal tab; must be insulated from heatsink unless system ground referenced.
3	Emitter	Power return path; common reference for load; internal resistor connection point for Darlington bias network.

Key Features

Feature	Design Value
Integrated base resistor	200 Ω pull-down enables direct TTL/CMOS interface without external bias components.
High ASO margin	Supports 20 A pulse (1 ms) and 15 A DC at T_c = 25 °C - critical for inductive load snubbing and surge tolerance.
Low V_BE(sat)	≤ −2.0 V at I_C/I_B = 500 - minimizes base drive power and improves overall efficiency in high-current stages.
Thermal stability	Specified junction temperature range −55 °C to +150 °C - ensures reliability in industrial ambient conditions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current Darlington transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
2SD1071	V_CEO = −100 V, I_C = −10 A, h_FE ≥ 1000, TO-3PB package, no internal base resistor	Higher voltage rating but lower current capacity; requires external base bias network	Select when >60 V rail operation is needed and board space allows discrete bias components.
BDW53C	V_CEO = −100 V, I_C = −12 A, h_FE ≥ 750, TO-218 package, no internal resistor	Lower h_FE, different mechanical footprint, higher V_CE(sat) (~2.5 V), requires redesign of base drive.	Choose only if legacy BDW53C footprint compatibility is mandatory and gain margin is acceptable.

Compared with 2SD1193, the 2SD1071 offers higher voltage headroom but demands external biasing and delivers less current, while BDW53C trades gain and saturation performance for wider voltage tolerance and non-compatible packaging-neither is pin-compatible, and both require circuit revision.

FAQ

What is the maximum safe collector-emitter voltage for 2SD1193?

The absolute maximum V_CEO rating for 2SD1193 is −60 V at T_a = 25 °C. Operation beyond this value-even momentarily-risks avalanche breakdown and permanent device failure. Derating is required above 25 °C ambient; consult the datasheet's Safe Operating Area chart for voltage-current limits at elevated temperatures. The 2SD1193 must never be used in life-support or aircraft control systems per SANYO's safety disclaimer.

Does 2SD1193 include an internal base resistor, and what is its value?

Yes, the 2SD1193 integrates a 200 Ω base-emitter resistor, confirmed in the Electrical Connection diagram and V_BE test conditions. This resistor enables direct logic-level drive from TTL or CMOS outputs without external bias components. It stabilizes turn-on behavior and prevents spurious conduction due to leakage or noise, distinguishing the 2SD1193 from standard Darlingtons like 2SD1071 which lack this feature.

What is the Safe Operating Area (ASO) behavior of 2SD1193 under pulsed conditions?

The 2SD1193 supports up to −20 A peak collector current (I_CP) in 1 ms pulses at T_c = 25 °C, as shown in ITR08576. Its ASO curve shows linear reduction in allowable current with increasing pulse width (10 ms, 100 ms) and decreasing with rising case temperature. For reliable design, always operate within the published ASO boundary-not just DC ratings-to avoid second breakdown during transient overloads.

Can 2SD1193 replace 2SB883 in the same circuit?

No-2SD1193 (NPN) and 2SB883 (PNP) are complementary devices with opposite polarity and non-interchangeable pinouts and biasing. While both share the TO-3PB package and appear together in the same datasheet (ENN1036B), substituting one for the other would reverse current flow and likely destroy the circuit. Their electrical characteristics-including V_CEO, h_FE, and saturation voltages-are specified separately and not symmetric.

What thermal derating applies to 2SD1193 above 25 °C case temperature?

2SD1193's collector dissipation (P_C) decreases linearly from 7 W at T_c = 25 °C to 0 W at T_c = 160 °C, per the PC–Tc curve (ITR08577). At T_c = 80 °C, P_C ≈ 4.2 W; at T_c = 120 °C, P_C ≈ 2.1 W. Heatsink selection must account for this slope, and junction temperature must remain ≤150 °C under worst-case power and ambient conditions to ensure reliability.
