Product details
Overview
SR510 B0G from Taiwan Semiconductor is a 5A, 100V Schottky barrier rectifier in DO-201AD package, featuring low forward voltage (0.85 V at 5 A, 25°C), high surge current capability (120 A), and AEC-Q101 qualification option. It serves as a primary output rectifier in high-efficiency DC/DC converters for automotive infotainment power supplies.
For engineers reviewing the SR510 B0G datasheet, SR510 B0G pinout, SR510 B0G application, or SR510 B0G equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, 125°C maximum junction temperature, 100 µA reverse leakage at 25°C, and suitability for space-constrained SMPS designs requiring low conduction loss.
Technical Context
This discrete Schottky diode uses a single-die construction with guard ring structure to enhance overvoltage ruggedness and suppress avalanche-induced failure. Its 6°C/W junction-to-case thermal resistance enables effective heat transfer to PCB copper when mounted with adequate pad area.
The device operates across –55°C to +125°C junction range (standard grade) and supports 8.3 ms half-sine surge currents up to 120 A without degradation. Reverse recovery is inherently negligible due to majority-carrier conduction, eliminating switching tail current in high-frequency topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or buck output stages |
| IF | 5 A - Continuous forward current rating at 75°C case temperature; sets baseline conduction capacity |
| VF | 0.85 V @ 5 A, 25°C - Low forward drop reduces I²R losses by ~30% vs. comparable 1N5822 in 12 V output rails |
| IR | 100 µA @ 100 V, 25°C - Low leakage preserves efficiency in standby mode of always-on automotive modules |
| IFSM | 120 A @ 8.3 ms - Withstands inrush surges during hot-plug events in industrial 24 V systems |
| TJ max | 125°C - Enables operation in under-hood environments without derating below 5 A at 85°C ambient |
| RθJC | 6°C/W - Allows direct thermal coupling to heatsink or large copper pour for sustained 5 A loads |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; leads are pure tin plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry point | Connected to lower-potential node (e.g., switch node in synchronous buck, transformer secondary center-tap) |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to output rail; polarity marking prevents misassembly in high-volume SMT reflow processes |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Prevents edge breakdown at rated VRRM, enabling stable 100 V operation without voltage derating in humid environments |
| AEC-Q101 qualified variant available | Validated for automotive power modules requiring zero defect rates over 15-year service life |
| RoHS & halogen-free | Complies with IEC 61249-2-21; eliminates brominated flame retardants for safer recycling and lead-free reflow compatibility |
| UL 94V-0 molding compound | Self-extinguishing encapsulation withstands 150°C continuous operation without charring or outgassing |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-50WQ10FN-M3/45 | Same 100 V VRRM, 5 A IF, but TO-220AC package; higher RθJA (40°C/W) limits PCB-only cooling | Requires heatsink for >3 A continuous; unsuitable for DO-201AD footprint replacement | Select only if mechanical mounting allows TO-220 and thermal budget permits heatsink integration |
| ON Semiconductor SB5100-E3/54 | Identical DO-201AD package and 100 V rating, but 0.92 V VF (max) and 200 µA IR at 25°C | Higher conduction loss and leakage reduce efficiency in battery-backed or thermally constrained designs | Acceptable for cost-sensitive non-automotive applications where 0.07 V VF penalty is tolerable |
Compared with VS-50WQ10FN-M3/45 and SB5100-E3/54, SR510 B0G delivers superior thermal performance in axial-leaded form factor and tighter leakage control-critical for automotive and industrial systems demanding long-term reliability without heatsinks.

FAQ
What is the maximum junction temperature rating for SR510 B0G?
The SR510 B0G has a maximum junction temperature (TJ) of +125°C under standard grading. This rating applies across its full operating current range and enables reliable use in under-dash automotive environments where ambient temperatures reach 85°C, provided PCB thermal design maintains junction rise within specification. The SR510 B0G datasheet confirms this value in the Absolute Maximum Ratings table.
Does SR510 B0G have AEC-Q101 qualification?
The SR510 B0G itself is not AEC-Q101 qualified; however, the SR510H variant (same electrical specs, marked "H") is explicitly qualified per AEC-Q101. The "B0G" suffix denotes green compound and ammo box packaging-not reliability grade. For automotive applications requiring qualification, SR510H must be specified; SR510 B0G remains suitable for industrial and commercial designs.
What is the forward voltage of SR510 B0G at 5 A and 125°C junction temperature?
The SR510 B0G forward voltage increases with temperature: while it is 0.85 V typical at 5 A and 25°C, the datasheet does not specify a maximum or typical VF at 125°C. However, Figure 4 (Typical Forward Characteristics) shows VF ≈ 0.72 V at 5 A and 125°C for the SR510 family. This reduction reflects the negative temperature coefficient of Schottky diodes and is confirmed across the SR509–SR520 group.
Can SR510 B0G replace SR506 in an existing design?
No-SR510 B0G (100 V VRRM) is not a direct replacement for SR506 (60 V VRRM). Although both share DO-201AD package and 5 A rating, substituting SR510 B0G introduces unnecessary voltage margin and may increase cost and VF (0.85 V vs. 0.70 V for SR506). Use SR510 B0G only where 100 V blocking is required; for 60 V designs, SR506 or SR506 B0G remains optimal.
What does the "B0G" suffix mean in SR510 B0G?
The "B0G" suffix in SR510 B0G indicates green molding compound (G) and ammo box packaging (B0 = 500 units per box). It does not denote AEC-Q101 qualification (which uses "H"), temperature grade, or electrical variant. This suffix aligns with Taiwan Semiconductor's ordering code system defined in the datasheet's Ordering Information section (Version J2105, Page 3).
