Product details
Overview
B0530W RHG from Taiwan Semiconductor is a 30 V, 500 mA surface-mount Schottky barrier diode in SOD-123 package, featuring VF = 0.430 V at IF = 500 mA, IFSM = 5.5 A, TJ(max) = 125 °C, and IR = 20 µA at VR = 15 V - used for efficient rectification in compact AC/DC adapters.
For engineers reviewing the B0530W RHG datasheet, B0530W RHG pinout, B0530W RHG application, or B0530W RHG equivalent, key selection criteria include forward voltage drop at rated current, reverse leakage at operating bias, surge capability, thermal resistance (RθJA = 244 °C/W), and SOD-123 footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode employs a single-die silicon construction optimized for low-loss DC output rectification in low-voltage switching power supplies. Its 30 V VRRM rating targets 12–24 V input rails, while the 0.430 V VF at 500 mA directly reduces conduction loss versus standard PN junction diodes.
The device operates within -55 °C to +125 °C junction temperature range and exhibits 170 pF junction capacitance at 0 V reverse bias, supporting stable high-frequency switching performance up to several hundred kHz without excessive capacitive loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - maximum repetitive reverse voltage before breakdown; sets upper limit for safe operation in 24 V nominal input SMPS designs |
| IF | 500 mA continuous forward current - defines steady-state output rectification capacity under thermal derating constraints |
| VF @ 500 mA | 0.430 V - measured forward voltage drop; determines conduction loss (0.215 W typical) and thermal rise in adapter secondary-side rectifiers |
| IFSM | 5.5 A - non-repetitive surge current capability; withstands inrush and transient overloads during startup or fault conditions |
| RθJA | 244 °C/W - junction-to-ambient thermal resistance; requires minimal copper area for thermal management in SOD-123 footprint |
| IR @ 15 V | 20 µA - reverse leakage current at 15 V reverse bias; ensures low standby power loss in no-load or light-load conditions |
| CJ @ 0 V | 170 pF - junction capacitance at zero bias; impacts high-frequency switching noise and EMI filter design in >100 kHz converters |
Pinout & Package
Package: SOD-123 - surface-mount plastic case with matte tin-plated leads, moisture sensitivity level 1 (J-STD-020), UL 94 V-0 rated molding compound, cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to transformer secondary or switch node; must handle 500 mA continuous and 5.5 A surge |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output capacitor and load; polarity marked by visible cathode band on package body |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at rated current | 0.430 V @ 500 mA - reduces conduction loss by ~40% vs. comparable PN diodes, improving adapter efficiency and thermal margin |
| SOD-123 footprint | Standardized 2.7 × 1.6 mm outline - enables direct placement in space-constrained consumer and industrial adapter PCBs |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS - meets environmental compliance requirements for global OEM shipments |
| High surge robustness | 5.5 A IFSM - sustains short-duration line transients and inrush currents without degradation in 8.3 ms half-sine test condition |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS33-E3/57T (Vishay) | 30 V VRRM, 3 A IF, VF = 0.52 V @ 3 A - higher current rating but higher VF at lower currents | Targeted at higher-power adapters (>10 W); larger DO-214AC package requires PCB redesign | Select when system demands >500 mA continuous current and board space allows larger footprint |
| RB520S-30T2R (ROHM) | 30 V VRRM, 200 mA IF, VF = 0.33 V @ 100 mA - lower VF at light loads but derates sharply above 200 mA | Optimized for ultra-low-power IoT devices; insufficient for 500 mA sustained operation | Select only for battery-powered or <2 W applications where peak current remains below 200 mA |
Compared with SS33-E3/57T and RB520S-30T2R, the B0530W RHG uniquely balances 500 mA continuous current, 0.430 V VF at that load, SOD-123 compactness, and 30 V rating - making it optimal for cost- and space-sensitive 5–12 W AC/DC adapters requiring reliable thermal performance without layout change.

FAQ
What is the maximum continuous forward current rating for B0530W RHG?
The B0530W RHG has a maximum continuous forward current (IF) rating of 500 mA at TA = 25 °C. Derating is required above ambient temperatures - for example, at 85 °C ambient, usable current drops to approximately 320 mA per the forward current derating curve in the datasheet. This rating reflects the device's thermal limits in the SOD-123 package with RθJA = 244 °C/W.
What is the forward voltage drop of B0530W RHG at its rated current?
The B0530W RHG exhibits a maximum forward voltage drop (VF) of 0.430 V at IF = 500 mA and TA = 25 °C. This value is guaranteed per electrical specifications and is critical for calculating conduction losses in power supply designs. At lower currents (e.g., 100 mA), VF drops to 0.375 V, further improving light-load efficiency.
Does B0530W RHG have a specified reverse leakage current, and under what conditions?
Yes, the B0530W RHG specifies a maximum reverse leakage current (IR) of 20 µA at VR = 15 V and TA = 25 °C. At VR = 30 V (its rated VRRM), IR rises to 130 µA. These values are measured per the datasheet's electrical specifications table and directly impact standby power consumption in adapter and lighting applications.
Is B0530W RHG compatible with lead-free reflow soldering processes?
Yes, the B0530W RHG features matte tin-plated leads compliant with J-STD-002 for solderability and is qualified for lead-free reflow soldering. Its moisture sensitivity level is rated at Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30 °C/60% RH without baking prior to assembly - simplifying manufacturing logistics.
What is the marking code printed on the B0530W RHG device body?
The B0530W RHG is marked with "SE" on its package body, as confirmed in the Absolute Maximum Ratings table. This 2-character code distinguishes it from the B0520LW (marked "SD") and B0540W (marked "SF") variants within the same family and enables visual identification during manual inspection or automated optical recognition.
