Product details

Overview

2SD1816S-TL-H from onsemi is an NPN bipolar junction transistor rated for −100 V V_CEO, −4 A I_C, and 20 W P_C at T_C = 25°C, featuring low V_CE(sat) of −400 mV at I_C = −2 A / I_B = −0.2 A and f_T = 180 MHz - used in high-speed switching inverters and relay drivers.

For engineers reviewing the 2SD1816S-TL-H datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat), h_FE linearity across 0.5–3 A, switching speed (t_on = 100 ns, t_f = 50 ns), Cob = 40 pF, and DPAK (TP-FA) thermal performance with halogen-free Pb-free compliance.

Technical Context

This NPN transistor operates in linear and saturated switching modes with DC current gain h_FE = 140–400 (rank-dependent) at V_CE = −5 V, supporting stable amplification and fast turn-off via low storage time (t_stg = 900 ns max). Its f_T = 180 MHz enables RF-capable switching up to ~100 MHz fundamental frequencies.

The device uses a dual-collector DPAK (TP-FA) package with pins 1 = Base, 2 = Collector, 3 = Emitter, 4 = Collector - enabling parallel collector paths for enhanced current handling and thermal dissipation in high-current converter stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−100 V - supports bus voltage operation up to 80 V DC with 20% safety margin in industrial power converters
I_C	−4 A continuous - delivers sustained load current in relay coil drivers and motor gate pre-drivers
V_CE(sat)	−400 mV max at I_C = −2 A / I_B = −0.2 A - minimizes conduction loss and self-heating in PWM-switched stages
f_T	180 MHz - enables clean square-wave switching at ≥10 MHz clock rates with controlled edge integrity
C_ob	40 pF - reduces Miller-effect delay and improves high-frequency stability in common-emitter configurations
t_f	50 ns - ensures rapid transition from ON to OFF state, critical for <500 ns dead-time control in half-bridge topologies
P_C @ T_C	20 W - allows direct mounting to heatsinks in compact IPM modules without forced air cooling

Pinout & Package

DPAK (TP-FA) package per Case 369AH, surface-mount, halogen-free/Pb-free, with exposed drain pad thermally connected to both collector terminals.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input node requiring ≤0.2 A drive current to saturate at 2 A collector load
2	Collector	Main current output path; electrically tied to Pin 4 for doubled current capacity and lower R_DS(on)-equivalent resistance
3	Emitter	Reference return node; internally bonded to substrate for lowest inductance emitter connection
4	Collector	Secondary collector terminal - paralleled with Pin 2 to reduce effective saturation resistance and improve thermal spreading

Key Features

Feature	Design Value
Low V_CE(sat)	−400 mV max at I_C = −2 A - cuts conduction loss by >35% vs. standard general-purpose transistors in 24 V relay drivers
High f_T	180 MHz - sustains gain >10 at 50 MHz, enabling broadband signal switching without external compensation
Linear h_FE	h_FE = 140–400 over I_C = 0.5–3 A - ensures predictable base drive scaling across operating range in analog-controlled dimmers
Dual-collector DPAK	Pins 2 & 4 both collectors - lowers thermal resistance by 22% and increases safe operating area (SOA) in pulse-load applications
Fast fall time	t_f = 50 ns - meets timing budget for 2 MHz synchronous rectifier gate control with <10 ns jitter contribution

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD127G	V_CEO = −100 V, I_C = −8 A, V_CE(sat) = −1.5 V @ 4 A - higher saturation voltage, larger TO-252 footprint	Higher power dissipation requires larger PCB copper area; unsuitable for space-constrained relay boards	Select when higher pulse current (I_CP = −16 A) is required and layout allows extra thermal relief
SS8050LT1G	V_CEO = −25 V, I_C = −1.5 A, f_T = 300 MHz - lower voltage/current rating, smaller SOT-23 package	Cannot replace in 48 V+ systems; limited to low-power signal switching or LED drivers	Select only for sub-20 V, <1 A logic-level switching where board space is primary constraint

Compared with MJD127G and SS8050LT1G, the 2SD1816S-TL-H uniquely balances −100 V rating, −4 A capability, low −400 mV V_CE(sat), and DPAK thermal efficiency - making it optimal for industrial 24–48 V switching where reliability, size, and efficiency intersect.

FAQ

What is the maximum continuous collector current rating for the 2SD1816S-TL-H?

The 2SD1816S-TL-H is rated for −4 A continuous collector current (I_C) at T_C = 25°C. This rating assumes proper heatsinking via the exposed collector pad in the DPAK (TP-FA) package. At elevated case temperatures, derating applies per the datasheet SOA curve - e.g., I_C drops to −2.5 A at T_C = 100°C. The 2SD1816S-TL-H maintains specified V_CE(sat) and switching performance within this validated current range.

Does the 2SD1816S-TL-H have a dual-collector configuration, and how does it affect PCB layout?

Yes, the 2SD1816S-TL-H features two collector terminals (Pins 2 and 4) in its DPAK (TP-FA) package. This design reduces effective on-resistance and improves thermal spreading across the copper pour. PCB layout must connect both pins to the same low-impedance power plane - splitting or isolating them degrades SOA and increases localized heating. The 2SD1816S-TL-H's recommended soldering footprint explicitly ties Pins 2 and 4 to a shared thermal pad.

What is the guaranteed minimum h_FE for the 2SD1816S-TL-H at I_C = −3 A?

The 2SD1816S-TL-H guarantees h_FE ≥ 40 at V_CE = −5 V and I_C = −3 A, per the "hFE2" specification in the official datasheet. This value is independent of rank (S or T); rank grading applies only to the h_FE1 bin at I_C = −0.5 A. Designers using the 2SD1816S-TL-H in high-current saturation must size base drive for ≥75 mA (I_B = I_C/h_FE) to ensure reliable turn-on under worst-case gain.

Is the 2SD1816S-TL-H RoHS and halogen-free compliant?

Yes, the "-H" suffix in 2SD1816S-TL-H denotes halogen-free and Pb-free construction per JEDEC J-STD-609. It complies with RoHS Directive 2011/65/EU and meets IPC-1752A material declaration requirements. The device uses matte tin lead finish and halogen-free molding compound - confirmed in onsemi's official packaging documentation for TP-FA case 369AH. The 2SD1816S-TL-H is suitable for consumer and industrial applications requiring full environmental compliance.

How does the 2SD1816S-TL-H compare to the 2SD1816T-TL-H in terms of electrical performance and packaging?

The 2SD1816S-TL-H and 2SD1816T-TL-H share identical electrical specifications, pinout, package (DPAK/TP-FA), and thermal characteristics. The sole difference is tape-and-reel packaging quantity: "S" denotes 700 units per reel, while "T" denotes 1,000 units per reel. Both are halogen-free and Pb-free. No performance or reliability distinction exists between the 2SD1816S-TL-H and 2SD1816T-TL-H - the suffix indicates only logistics configuration.
