Product details
Overview
S1DBHR5G from Taiwan Semiconductor is a 1 A, 200 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 capability - used in AC/DC front-end stages of compact switching power supplies.
For engineers reviewing the S1DBHR5G datasheet, S1DBHR5G pinout, S1DBHR5G application, or S1DBHR5G equivalent, key selection criteria include repetitive peak reverse voltage (200 V), thermal resistance (30 °C/W), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and SMB footprint 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 up to 1 A at 75 °C lead temperature. Its 30 °C/W junction-to-lead thermal resistance enables direct PCB heat conduction without heatsinking in low-power adapters.
The device exhibits ≤5 µA reverse leakage at 25 °C and ≤50 µA at 125 °C under rated reverse voltage, with 12 pF junction capacitance at 4 V bias and 1 MHz - suitable for non-high-frequency rectification where EMI filtering is managed externally.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - blocks up to 200 V repetitive reverse voltage in bridge or single-phase rectifier configurations |
| IF | 1 A - continuous average forward current rating at 75 °C lead temperature |
| IFSM | 30 A - withstands 8.3 ms half-sine surge, enabling robustness against line transients in SMPS input stages |
| VF | ≤1.1 V @ 1 A, 25 °C - minimizes conduction loss and self-heating in compact, thermally constrained designs |
| RθJL | 30 °C/W - allows direct thermal path from die to PCB copper, supporting natural convection cooling |
| IR | ≤5 µA @ 25 °C - ensures low standby power loss in offline power supplies with high-impedance feedback networks |
Pinout & Package
DO-214AA (SMB) surface-mount package with cathode-indicating band; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance; UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or transformer secondary; must route with adequate copper area for thermal dissipation |
| Cathode | Forward current exit / reverse voltage blocking terminal | Marked by band; ties to output capacitor positive or DC bus; polarity critical for correct rectification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R02 | 1 A, 200 V, TO-277 package (SMD but larger than SMB); VF = 1.05 V typical | Higher thermal mass; requires larger pad layout and may need thermal relief adjustment | Select when higher surge margin or legacy board reuse is prioritized over footprint miniaturization |
| ON Semi MUR120 | 1 A, 200 V, DO-41 through-hole; faster recovery (trr ≈ 50 ns vs. ~2 µs for S1DBHR5G) | Not surface-mount; incompatible with automated SMT lines unless using adapter carriers | Choose only for prototyping or low-volume through-hole builds where fast recovery is needed |
Compared with STTH1R02 and MUR120, the S1DBHR5G delivers optimal balance of SMB footprint, J-STD-020 Level 1 handling, and cost-effective standard recovery performance - making it preferred for high-volume, space-constrained AC/DC converters where ultrafast recovery is unnecessary.

FAQ
What is the maximum junction temperature rating for the S1DBHR5G?
The S1DBHR5G has a maximum junction temperature (TJ) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating applies across the full operating range and supports reliable operation in enclosed power supplies with limited airflow. Derating curves confirm usable current capacity down to 0.5 A at 125 °C ambient when mounted on 1-inch² 2-oz copper.
Does the S1DBHR5G meet J-STD-020 moisture sensitivity requirements?
Yes, the S1DBHR5G is rated at Moisture Sensitivity Level 1 per J-STD-020, meaning it has unlimited floor life before reflow soldering and does not require dry-packaging or baking prior to assembly. This simplifies SMT line logistics and reduces risk of popcorning during reflow - a key advantage over MSL 2a or higher alternatives.
Is the S1DBHR5G halogen-free and RoHS compliant?
Yes, the S1DBHR5G complies with both RoHS Directive 2011/65/EU and IEC 61249-2-21 for halogen-free materials. The molding compound contains no brominated flame retardants, chlorine, or fluorine above threshold limits, and the matte tin-plated leads meet Pb-free soldering standards - confirmed in TSC's official product declaration documents.
What is the forward voltage specification for the S1DBHR5G at 1 A and 125 °C?
The S1DBHR5G forward voltage is specified as ≤1.1 V at 1 A and 25 °C. While the datasheet does not provide a guaranteed max VF at 125 °C, typical characterization curves show VF increases to approximately 0.95 V at that temperature due to negative temperature coefficient - still well within design margins for most 200 V rectifier applications.
Can the S1DBHR5G be used as a direct replacement for the S1DB in existing designs?
Yes, the S1DBHR5G is a direct form-fit-function replacement for the S1DB, sharing identical DO-214AA (SMB) package, pinout, electrical ratings (VRRM = 200 V, IF = 1 A), and thermal performance. The "HR5G" suffix denotes halogen-free and green compound compliance - no layout or schematic changes are required when upgrading from S1DB to S1DBHR5G.
