Product details

Overview

RS1B-E3/5AT from Vishay General Semiconductor is a surface-mount fast switching rectifier diode in SMA (DO-214AC) package, rated for 100 V repetitive peak reverse voltage (V_RRM), 1.0 A average forward current (I_F(AV)), and 150 ns reverse recovery time (t_rr). It features glass passivated junction, 30 A surge capability (I_FSM), and 1.3 V forward voltage at 1.0 A - optimized for high-efficiency power supply rectification in space-constrained consumer and automotive systems.

For engineers reviewing the RS1B-E3/5AT datasheet, RS1B-E3/5AT pinout, RS1B-E3/5AT application, or RS1B-E3/5AT equivalent, key selection criteria include its 100 V V_RRM, 150 ns t_rr, SMA package thermal resistance (R_θJA = 105 °C/W), AEC-Q101 qualification eligibility (via HE3 suffix), and compatibility with automated SMT placement per J-STD-002.

Technical Context

The RS1B-E3/5AT implements a single silicon PN junction with glass passivation for stable fast-switching performance and enhanced reliability under thermal cycling. Its 150 ns reverse recovery time enables efficient operation in 50–100 kHz SMPS topologies, while the 30 A non-repetitive surge rating supports transient load handling in DC-DC converters and freewheeling paths.

Designed for surface-mount assembly on PCBs with 5.0 mm × 5.0 mm copper pads, the device meets MSL Level 1 per J-STD-020 and achieves 260 °C lead-free solder peak temperature tolerance. Polarity is marked by a cathode band; terminals are matte tin plated and whisker-resistant per JESD 201 Class 2.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - maximum repetitive reverse blocking voltage; defines usable input range in 12–48 V DC-DC front-end rectifiers
I_F(AV)	1.0 A at T_L = 90 °C - continuous DC output capability with standard PCB copper pad thermal management
t_rr	150 ns - enables high-frequency switching with low commutation loss in flyback and buck-derived topologies
V_F	1.3 V at I_F = 1.0 A - contributes to <1.3 W conduction loss at full load, supporting thermally constrained layouts
I_FSM	30 A (8.3 ms half-sine) - withstands inrush and short-circuit transients without failure in power supply inputs
T_J max.	150 °C - allows operation in under-hood automotive environments and sealed industrial enclosures
C_J	7.0 pF at 4.0 V, 1 MHz - minimizes capacitive coupling noise in high-dv/dt gate-drive or signal-path freewheeling applications

Pinout & Package

SMA (DO-214AC) package: surface-mount, low-profile (max height 2.29 mm), molded UL 94 V-0 compound, cathode indicated by color band. Matte tin-plated leads comply with J-STD-002 solderability and JESD 22-B102.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L06U	600 V V_RRM, 1.0 A I_F(AV), 75 ns t_rr, TO-277 package	Higher voltage rating and faster recovery, but larger footprint and higher V_F (1.7 V)	Select when >100 V blocking or <100 ns t_rr is required; not drop-in due to TO-277 mechanical mismatch
ON Semi MUR110E	100 V V_RRM, 1.0 A I_F(AV), 75 ns t_rr, SMA package, 1.25 V V_F	Near-identical voltage/current ratings and package, but faster recovery and slightly lower V_F	Drop-in alternative only if layout accommodates tighter t_rr-driven EMI filtering; verify thermal derating with R_θJA = 110 °C/W

Compared with STTH1L06U and MUR110E, RS1B-E3/5AT offers balanced trade-offs: moderate 150 ns t_rr and 1.3 V V_F in a widely supported SMA footprint, with verified MSL Level 1 and automotive qualification pathways - making it optimal for cost-sensitive, volume-manufactured consumer and industrial power supplies where extreme speed is unnecessary.

FAQ

What is the maximum junction temperature rating for RS1B-E3/5AT?

The RS1B-E3/5AT has a maximum operating junction temperature (T_J) of +150 °C, enabling reliable operation in high-ambient environments such as automotive under-hood locations or sealed industrial enclosures. This rating is validated per the Vishay datasheet Document Number 88707 and applies across the full specified storage and operating range of −55 °C to +150 °C. The RS1B-E3/5AT must be thermally managed using recommended PCB copper pad areas to maintain this limit under full load.

Is RS1B-E3/5AT RoHS-compliant and lead-free solder compatible?

Yes, RS1B-E3/5AT is RoHS-compliant and designed for lead-free soldering processes. Its "E3" suffix denotes commercial-grade, RoHS-compliant construction with matte tin-plated leads that meet J-STD-002 solderability requirements and withstand peak reflow temperatures up to 260 °C per J-STD-020 MSL Level 1. The RS1B-E3/5AT does not contain lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits defined in Directive 2011/65/EU.

What does the "5AT" in RS1B-E3/5AT indicate?

The "5AT" in RS1B-E3/5AT is Vishay's preferred package code denoting 13-inch diameter plastic tape-and-reel packaging containing 7,500 units per reel. This format is optimized for high-volume automated SMT placement equipment. The base part RS1B-E3 remains electrically and mechanically identical across all package codes (e.g., 61T = 7-inch reel, 5AT = 13-inch reel); only packaging and quantity differ. RS1B-E3/5AT is functionally interchangeable with RS1B-E3/61T in circuit design.

How does RS1B-E3/5AT compare to RS1J-E3/5AT in terms of voltage rating?

RS1B-E3/5AT is rated for 100 V maximum repetitive peak reverse voltage (V_RRM), whereas RS1J-E3/5AT is rated for 600 V V_RRM. Both share identical package (SMA), forward current (1.0 A), surge rating (30 A), and thermal characteristics, but differ only in breakdown voltage and associated reverse recovery time (RS1B: 150 ns; RS1J: 500 ns). Select RS1B-E3/5AT for 12–48 V systems; use RS1J-E3/5AT only when 600 V blocking is required, accepting slower switching.

Can RS1B-E3/5AT be used in automotive applications?

RS1B-E3/5AT itself is commercial-grade (E3 suffix), but the RS1B family supports AEC-Q101 qualification via the HE3 suffix (e.g., RS1BHE3_A/I). For automotive use, specify RS1BHE3_A/I - which shares identical electrical specs and SMA package but adds stress testing per AEC-Q101. RS1B-E3/5AT may be used in non-safety-critical automotive subsystems if qualified per internal requirements, but RS1BHE3_A/I is the designated automotive-grade variant of RS1B-E3/5AT.
