Product details
Overview
SR506 B0G from Taiwan Semiconductor is a 5A, 60V Schottky barrier rectifier in DO-201AD package, featuring low forward voltage (0.70 V max at 5A, 25°C), high surge current capability (120 A), and junction temperature rating up to +150°C. It serves as a primary output rectifier in high-efficiency DC/DC converters and AC/DC adapters.
For engineers reviewing the SR506 B0G datasheet, SR506 B0G pinout, SR506 B0G application, or SR506 B0G equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, 10 mA reverse leakage at 100°C, 6 °C/W junction-to-case thermal resistance, and AEC-Q101 qualification eligibility via H-suffix variants.
Technical Context
This single-die Schottky rectifier uses a planar guard ring structure to enhance overvoltage robustness and suppress avalanche-induced failure. Its low VF enables reduced conduction loss in high-frequency switching topologies where duty cycle and thermal management are critical.
The device operates across -55°C to +150°C junction temperature range with 35 °C/W junction-to-ambient thermal resistance in standard PCB mount conditions. Its 10,000 V/µs critical dv/dt rating supports reliable operation in fast-switching SMPS designs without snubber networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum non-repetitive reverse blocking voltage; defines safe operating limit in flyback or forward converter secondary side |
| IF | 5 A - Continuous average forward current; sets minimum heatsinking requirement for sustained 5A load |
| VF (max) | 0.70 V @ 5A, 25°C - Directly determines conduction loss (3.5 W at 5A); lower than Si diodes enabling >90% efficiency in 12V-output converters |
| IFSM | 120 A - Peak non-repetitive surge current; withstands inrush and transient overload without bond wire fusing |
| IR (max) | 10 mA @ 60 V, 100°C - Reverse leakage level affecting standby power and thermal runaway risk in parallel configurations |
| RθJC | 6 °C/W - Enables direct thermal path to heatsink; allows ~110°C junction rise at 5A with 66°C case temp |
| TJ max | +150°C - Extended temperature rating supports under-hood automotive modules and industrial enclosures without derating |
Pinout & Package
Package: DO-201AD - Axial leaded, molded plastic case meeting UL 94V-0; cathode indicated by band; pure tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., transformer center-tap or switch node return) in half-wave rectification |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail; polarity band identifies this terminal for correct PCB orientation and ESD-safe handling |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Prevents edge breakdown at rated VRRM, enabling stable 60 V blocking without field plate or mesa etch |
| Low VF at high IF | 0.70 V max at 5A ensures <3.5 W conduction loss-critical for thermally constrained adapter PCBs |
| AEC-Q101 qualification path | H-suffix variants (e.g., SR506H) meet stress test requirements for automotive power modules |
| Halogen-free molding compound | Complies with IEC 61249-2-21; eliminates brominated flame retardants for RoHS-compliant industrial assembly |
Applications
| Server Power Supply | Automotive DC/DC Converter |
|---|---|
Use Scenario: Secondary-side synchronous rectification replacement in 48V–12V buck-derived server PSU modules. IC Role / Device Role / Timing Role: Discrete Schottky rectifier replacing MOSFET+driver in cost-sensitive, medium-efficiency designs. Use Value: Eliminates gate drive complexity while maintaining <0.7 V forward drop-reducing BOM count and layout area vs. active solutions. | Use Scenario: 12V auxiliary supply rectification in engine control units exposed to under-hood temperatures up to +125°C ambient. IC Role / Device Role / Timing Role: Primary output rectifier handling pulsed load transients during cold-crank events. Use Value: 120 A IFSM withstands 5× cold-crank surge without degradation; +150°C TJ rating avoids thermal shutdown in sealed enclosures. |
| Laptop Adapter | Industrial PoE PSE |
Use Scenario: Output rectification in compact 65W GaN-based USB-C PD adapters operating at 100–200 kHz. IC Role / Device Role / Timing Role: High-frequency Schottky rectifier minimizing switching losses in discontinuous conduction mode (DCM). Use Value: 10,000 V/µs dv/dt rating prevents false turn-on during fast voltage transitions; low capacitance (<100 pF) preserves EMI performance. | Use Scenario: Auxiliary power rectification in IEEE 802.3bt Type 4 PoE power sourcing equipment with 57 V nominal input. IC Role / Device Role / Timing Role: Input-stage clamp and rectifier in isolated auxiliary bias winding circuits. Use Value: 60 V VRRM provides 20% margin above 57 V PoE spec; 10 mA IR at 100°C ensures stable bias under full-load thermal stress. |
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-50SQ060 | Same DO-201AD package, 5A/60V rating, but VF = 0.68 V typ (vs. 0.70 V max for SR506 B0G); RθJC = 5.5 °C/W | Slightly lower conduction loss; tighter VF distribution beneficial in parallel arrays | Preferred where thermal margin is constrained and VF matching matters |
| ON Semiconductor SB560 | DO-201AD, 5A/60V, VF = 0.72 V max; no AEC-Q101 path; RθJC = 7.5 °C/W | Higher thermal resistance limits continuous 5A operation on minimal copper; not qualified for automotive | Cost-optimized alternative for consumer-grade adapters with relaxed thermal specs |
Compared with VS-50SQ060 and SB560, SR506 B0G offers balanced trade-offs: tighter thermal resistance than SB560, broader qualification path than VS-50SQ060, and consistent 0.70 V max VF across production lots-enabling predictable loss budgeting in volume production.

FAQ
What is the maximum junction temperature rating for SR506 B0G?
The SR506 B0G has a maximum junction temperature of +150°C, verified per TSC's absolute maximum ratings table. This allows uninterrupted operation in environments where case temperatures reach +110°C under 5A load, given its 6 °C/W junction-to-case thermal resistance. The SR506 B0G must be mounted on PCB copper areas ≥ 100 mm² to sustain this rating continuously.
Is SR506 B0G AEC-Q101 qualified?
The SR506 B0G marking indicates standard qualification; AEC-Q101 qualification applies only to H-suffix variants like SR506H. While SR506 B0G shares identical die and construction, it has not undergone the full AEC-Q101 stress test sequence. For automotive applications requiring formal qualification, SR506H must be specified instead of SR506 B0G.
What is the reverse leakage current of SR506 B0G at elevated temperature?
At 60 V reverse bias and +100°C junction temperature, the SR506 B0G exhibits a maximum reverse leakage current of 10 mA, as specified in the electrical characteristics table. This value increases to ~15 mA at +125°C for SR502–SR504 variants, but SR505–SR506 maintain the 10 mA limit up to +100°C-critical for standby power budgeting in energy-efficient designs.
Does SR506 B0G have a guard ring structure?
Yes, the SR506 B0G incorporates a diffusion-guard ring design explicitly stated in the features list. This structure mitigates electric field crowding at the silicon periphery, improving reliability under repetitive overvoltage transients and extending lifetime in unregulated input applications such as universal-input offline SMPS.
What packaging options are available for SR506 B0G?
SR506 B0G is supplied in 500-unit ammo boxes (B0G suffix), per the ordering information table. Tape-and-reel packaging (1,250 units) uses the base code SR506 without suffix. No other packaging formats-including bulk, tube, or tray-are supported for SR506 B0G per TSC's official documentation.
