Product details

Overview

S1BHR3G from Taiwan Semiconductor is a surface-mount general-purpose silicon rectifier diode with 100 V repetitive peak reverse voltage (V_RRM), 1 A average forward current (I_F), and DO-214AC (SMA) package - used in DC-DC converters, snubber networks, and lighting power supplies.

For engineers reviewing the S1BHR3G datasheet, S1BHR3G pinout, S1BHR3G application, or S1BHR3G equivalent, key selection criteria include its 1.1 V max forward voltage at 1 A, 50 µA max reverse leakage at 125°C, 1500 ns reverse recovery time, junction-to-lead thermal resistance of 27°C/W, and RoHS/halogen-free compliance for industrial-grade reliability.

Technical Context

This device is a single-die, glass-passivated PN-junction rectifier optimized for switching-mode power conversion. It operates across -55°C to +175°C junction temperature range and supports automated placement per J-STD-020 Level 1 moisture sensitivity.

Its electrical behavior is defined by a 1.1 V forward voltage drop at rated 1 A load, 1 µA reverse current at 25°C, and 1500 ns reverse recovery time under standardized test conditions (I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A), confirming suitability for medium-frequency rectification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - maximum non-repetitive reverse voltage the diode blocks without breakdown
I_F	1 A - continuous average forward current rating at T_L = 75°C
V_F (max)	1.1 V @ I_F = 1 A, T_J = 25°C - determines conduction loss in power stage
I_R (max)	50 µA @ V_R = 100 V, T_J = 125°C - defines leakage-related standby power loss
t_rr	1500 ns - limits usable switching frequency in hard-switched topologies
R_θJL	27 °C/W - enables thermal design using lead temperature as proxy for junction temp
Package	DO-214AC (SMA) - industry-standard surface-mount outline with cathode band polarity marking

Pinout & Package

DO-214AC (SMA) package with axial-leaded planar construction: anode and cathode terminals formed on opposite ends of molded body; polarity indicated by black cathode band.

Pin/Terminal	Circuit Role	Design Meaning

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 M100S1G	V_RRM = 100 V, I_F = 1 A, t_rr = 1500 ns, same DO-214AC package	Identical electrical envelope; minor VF variation (1.05 V typ vs. 1.1 V max)	Drop-in replacement where tighter VF distribution is required
Vishay VS-1EWH01-M3/5AT	V_RRM = 100 V, I_F = 1 A, t_rr = 1000 ns, DO-214AC package	Faster recovery (1000 ns) but higher V_F (1.15 V max); slightly higher R_θJA	Preferred for higher-frequency snubbers where trr dominates loss

Compared with M100S1G and VS-1EWH01-M3/5AT, the S1BHR3G offers balanced conduction/recovery trade-off and superior thermal resistance (R_θJL = 27°C/W), making it optimal for thermally constrained, medium-frequency rectification where lead temperature monitoring is used.

FAQ

What is the maximum junction temperature rating for S1BHR3G?

The S1BHR3G has a maximum junction temperature (T_JMAX) of +175°C, enabling operation in high-ambient environments such as enclosed LED drivers or industrial control enclosures. This rating is validated per absolute maximum ratings table and supported by thermal derating curves showing sustained 1 A current capability up to 75°C lead temperature. The S1BHR3G maintains specified electrical parameters within this range when operated within its thermal limits.

Is S1BHR3G compatible with lead-free reflow soldering processes?

Yes, the S1BHR3G features matte tin-plated leads compliant with J-STD-002 and rated for lead-free reflow profiles (peak temperature ≤ 260°C). Its moisture sensitivity level is J-STD-020 Level 1, meaning no pre-bake is required before assembly. The DO-214AC package and UL 94V-0 molding compound further ensure process robustness in standard SMT lines handling the S1BHR3G.

What does the 'HR3G' suffix indicate in S1BHR3G?

The 'HR3G' suffix in S1BHR3G denotes Taiwan Semiconductor's internal packaging and environmental coding: 'H' indicates halogen-free compliance per IEC 61249-2-21, 'R3' specifies tape-and-reel packaging (7,500 pcs per reel), and 'G' signifies green (halogen-free) molding compound. This matches the ordering code structure defined in the datasheet where 'x' in S1x represents voltage grade (B = 100 V), and suffixes convey material and packing details for the S1BHR3G variant.

How does the reverse recovery time of S1BHR3G affect its use in switching circuits?

The S1BHR3G has a reverse recovery time (t_rr) of 1500 ns under standard test conditions (I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A), classifying it as a general-purpose, not ultrafast, rectifier. In practice, this limits efficient operation to switching frequencies below ~100 kHz. Using the S1BHR3G above this range increases switching losses and EMI; for higher-frequency designs, alternatives with t_rr < 500 ns should be evaluated.

Can S1BHR3G replace S1BG in existing designs?

Yes, S1BHR3G is a direct functional and mechanical replacement for S1BG: both share identical V_RRM (100 V), I_F (1 A), DO-214AC package, and pinout. The 'HR3G' suffix adds halogen-free and enhanced environmental compliance without altering electrical or thermal specs. No PCB or schematic changes are needed when upgrading from S1BG to S1BHR3G, and the S1BHR3G maintains full compatibility with legacy S1BG layouts and thermal models.
