Product details

Overview

HS1D R3G from Taiwan Semiconductor is a 200 V, 1 A high-efficiency surface-mount silicon rectifier diode in DO-214AC (SMA) package, featuring 50 ns reverse recovery time, 1.0 V forward voltage at 1 A, and 30 A peak surge current - used in DC/DC converters, snubber circuits, and freewheeling paths.

For engineers reviewing the HS1D R3G datasheet, HS1D R3G pinout, HS1D R3G application, or HS1D R3G equivalent, key selection criteria include V_RRM = 200 V, I_F = 1 A, t_rr = 50 ns, thermal resistance R_θJA = 70 °C/W, and DO-214AC mechanical compatibility with automated SMT assembly.

Technical Context

This device is a single-die, glass-passivated PN junction rectifier optimized for fast switching in high-frequency power conversion. Its 50 ns reverse recovery time and low 1.0 V forward voltage at rated current support efficiency in SMPS topologies operating up to several hundred kHz.

Thermally, it delivers R_θJL = 15 °C/W and R_θJA = 70 °C/W on a 5 mm × 5 mm Cu pad PCB, enabling reliable operation up to T_J = 150 °C. Moisture sensitivity is Level 1 per J-STD-020, supporting standard reflow without dry-pack requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum repetitive reverse voltage; defines safe blocking capability in 200 V-rated DC bus or flyback clamp applications
I_F	1 A continuous - average forward current rating; supports steady-state conduction in low-power SMPS outputs
t_rr	50 ns - reverse recovery time; enables efficient operation in 100–500 kHz switching converters with minimal switching loss
V_F	1.0 V @ 1 A, 25°C - forward voltage drop; contributes ~1 W conduction loss at full load, critical for thermal budgeting
I_FSM	30 A - non-repetitive surge current; withstands inrush and transient overloads in power supply startup or fault conditions
R_θJA	70 °C/W - junction-to-ambient thermal resistance on standard test board; determines required PCB copper area for thermal management
C_J	20 pF @ 4 V - junction capacitance; impacts high-frequency noise coupling and EMI filter design in snubber and flyback circuits

Equivalent & Alternatives

The following parts are listed as comparable options for similar rectifier diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR120	V_RRM = 200 V, t_rr = 75 ns, V_F = 0.93 V @ 1 A - slower recovery but slightly lower forward drop	Higher t_rr may increase switching loss in >300 kHz designs; suitable where ultra-fast recovery is not critical	Prefer HS1D R3G for higher-frequency SMPS; choose MUR120 if lower V_F dominates thermal design
Vishay VS-1N5819HM3/81	V_RRM = 40 V, I_F = 1 A, t_rr ≈ 40 ns - lower voltage rating, Schottky construction	Not interchangeable for 200 V blocking; only viable in ≤40 V systems requiring lowest possible V_F	Select HS1D R3G for 200 V applications; use VS-1N5819HM3/81 only in low-voltage, high-efficiency DC/DC where V_RRM ≤ 40 V suffices

Compared with MUR120 and VS-1N5819HM3/81, HS1D R3G uniquely balances 200 V blocking, 50 ns recovery, and 1.0 V forward drop in DO-214AC - making it optimal for mid-voltage, medium-frequency power conversion where both voltage headroom and switching speed matter.

FAQ

What is the maximum junction temperature rating for HS1D R3G?

The HS1D R3G has a maximum junction temperature (T_J) rating of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version M2401). This allows reliable operation in thermally demanding environments such as enclosed power supplies or automotive under-hood applications, provided PCB thermal design maintains junction temperature below this limit. Derating curves confirm usable current capacity down to 0.5 A at 125 °C ambient on standard test board.

Does HS1D R3G have a specified moisture sensitivity level (MSL)?

Yes, HS1D R3G is rated at Moisture Sensitivity Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30 °C/60% RH and subjected to standard lead-free reflow profiles without preconditioning or baking. This eliminates handling overhead in SMT lines and supports just-in-time manufacturing - a key advantage over higher-MSL diodes like some TO-220 or DPAK rectifiers.

What is the reverse recovery time (t_rr) of HS1D R3G and how is it measured?

The reverse recovery time of HS1D R3G is 50 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, per the Taiwan Semiconductor electrical specifications table. This value reflects its fast-switching capability and is critical for minimizing switching losses in high-frequency converters - notably distinguishing it from general-purpose rectifiers like 1N4007 (t_rr > 2 µs).

Is HS1D R3G RoHS and halogen-free compliant?

Yes, HS1D R3G is fully RoHS compliant and halogen-free, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet (Version M2401). This compliance aligns with EU Directive 2011/65/EU and IPC-1752A reporting standards, making HS1D R3G suitable for export-controlled and environmentally regulated end products including consumer electronics and industrial equipment.

What does the 'R3G' suffix in HS1D R3G indicate?

The 'R3G' suffix in HS1D R3G denotes Taiwan Semiconductor's internal packaging and environmental coding: 'R3' specifies tape-and-reel packaging (7,500 units per reel), and 'G' indicates green (halogen-free) molding compound. This matches the ordering information table in the datasheet and confirms the device is supplied in standard SMT-ready format with eco-friendly materials - no additional markings or date codes are implied by this suffix.
