Product details
Overview
S1JB R5G from Taiwan Semiconductor is a 1 A, 600 V standard surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring glass-passivated junction, low forward voltage drop (≤1.1 V at 1 A), and 30 A surge current capability; used in AC/DC front-end rectification for offline SMPS and LED lighting drivers.
For engineers reviewing the S1JB R5G datasheet, S1JB R5G pinout, S1JB R5G application, or S1JB R5G equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (30 °C/W), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and SMB package compatibility with automated placement.
Technical Context
This single-die standard recovery rectifier operates with a maximum junction temperature of 150 °C and supports continuous forward current of 1 A at case temperature ≤75 °C. Its 600 V VRRM rating enables use in universal-input (85–265 VAC) power supplies.
The device exhibits 5 µA max reverse leakage at 25 °C and 50 µA at 125 °C under rated reverse voltage, with 12 pF typical junction capacitance at 4 V reverse bias and 1 MHz - critical for EMI filtering and switching loss estimation in flyback and buck-derived topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports 420 VRMS input, enabling universal AC line operation without derating |
| IF | 1 A continuous - suitable for low-to-medium power outputs up to ~15 W in non-PFC designs |
| IFSM | 30 A (8.3 ms half-sine) - withstands inrush surges in capacitor-input rectifiers |
| VF | ≤1.1 V @ 1 A, 25 °C - limits conduction loss to ≤1.1 W at full load, aiding thermal design |
| RθJL | 30 °C/W - enables direct heatsinking via PCB copper; 75 °C case temp yields 150 °C junction |
| CJ | 12 pF @ 4 V, 1 MHz - impacts high-frequency noise coupling and snubber sizing |
| MSL | Level 1 (J-STD-020) - no bake required before reflow; compatible with standard SMT processes |

Use Value: 30 °C/W RθJL allows direct thermal coupling to 1 oz copper pour, eliminating need for thermal vias. | Use Scenario: Secondary-side rectification in isolated DC-DC modules (e.g., 48 V to 12 V). IC Role / Device Role / Timing Role: Output rectifier in non-synchronous buck-derived topologies. Use Value: 12 pF CJ reduces high-frequency ringing during turn-off, easing EMI filter design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR160G | Ultrafast recovery (trr ≈ 50 ns vs. S1JB R5G's ~2 µs); same 1 A/600 V rating and SMB package | Better suited for higher-frequency (>100 kHz) converters where reverse recovery loss dominates | Select MUR160G only if operating frequency exceeds 75 kHz or EMI constraints demand lower trr |
| Vishay VS-1N4007-M3/54 | General-purpose 1 A/1000 V rectifier in DO-41 through-hole package; not surface-mountable | Requires manual assembly or wave soldering; unsuitable for fully automated SMT lines | Choose VS-1N4007-M3/54 only for prototyping or legacy through-hole designs where rework is acceptable |
Compared with MUR160G and VS-1N4007-M3/54, the S1JB R5G delivers optimal cost-performance balance for <100 kHz SMPS with automated manufacturing - offering SMB compatibility, J-STD-020 Level 1 handling, and verified 600 V transient margin without ultrafast recovery overhead.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for S1JB R5G?
The S1JB R5G has a VRRM of 600 V, confirmed in the Absolute Maximum Ratings table across all versions of the S1AB–S1MB datasheet (I2102). This rating ensures safe operation under worst-case AC line conditions including 265 VAC with margin for transients. The S1JB R5G is not rated for 800 V or higher - that applies only to S1KB and S1MB variants.
Is S1JB R5G suitable for automated SMT assembly?
Yes, the S1JB R5G is explicitly designed for automated placement per its datasheet features. It carries J-STD-020 Moisture Sensitivity Level 1, requires no pre-bake, and uses matte tin-plated leads compliant with J-STD-002 solderability standards - all validated for standard reflow profiles in DO-214AA (SMB) footprint layouts.
What is the forward voltage drop (VF) of S1JB R5G at rated current?
The S1JB R5G exhibits a maximum forward voltage drop of 1.1 V at 1 A forward current and 25 °C junction temperature, as specified in the Electrical Specifications table. At 125 °C, VF decreases slightly due to semiconductor physics, but the 1.1 V limit remains the design-relevant worst-case value for thermal calculations.
Does S1JB R5G have halogen-free and RoHS-compliant construction?
Yes, the S1JB R5G meets both RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21, as stated in the Features section of the official TSC datasheet. The molding compound and plating materials are certified to these standards, making it suitable for export to EU, China, and other regulated markets.
What is the thermal resistance (RθJL) of S1JB R5G, and how does it impact PCB layout?
The S1JB R5G has a typical junction-to-lead thermal resistance of 30 °C/W, measured per JEDEC standards. This value assumes direct thermal conduction from the cathode/anode leads to large copper areas; designers should allocate ≥100 mm² of 1 oz copper per lead to maintain TJ ≤150 °C at full 1 A load, as shown in the Forward Current Derating Curve.
