Product details
Overview
SR106 B0G from Taiwan Semiconductor is a 1 A, 60 V Schottky barrier rectifier in DO-204AL (DO-41) package, featuring low forward voltage (0.70 V at 1 A, 25°C), high surge current capability (30 A), and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in compact DC/DC converters requiring high efficiency and thermal robustness.
For engineers reviewing the SR106 B0G datasheet, SR106 B0G pinout, SR106 B0G application, or SR106 B0G equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, 125°C maximum junction temperature, RoHS- and halogen-free compliance, and suitability for space-constrained power supplies where low conduction loss is critical.
Technical Context
This Schottky rectifier uses a single-die construction with guard ring structure to enhance overvoltage ruggedness and suppress avalanche failure. Its 10,000 V/µs critical dv/dt rating supports stable operation in fast-switching topologies like synchronous buck and flyback converters.
Thermal performance is defined by a junction-to-ambient thermal resistance of 90°C/W under standard PCB mounting conditions. The device operates across –55°C to +125°C junction range (derated above 125°C per curve), with reverse leakage limited to 500 µA at 25°C and 5 mA at 100°C under rated 60 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; sets upper limit for output rectification in 48 V bus-derived DC/DC stages |
| IF | 1 A continuous - Rated average forward current; defines steady-state power delivery capacity at ≤125°C ambient with adequate heatsinking |
| IFSM | 30 A - Non-repetitive surge current (8.3 ms half-sine); enables survival during output short-circuit or cold-start inrush events |
| VF | 0.70 V @ 1 A, 25°C - Low conduction loss reduces power dissipation and improves system efficiency vs. PN diodes |
| IR | 500 µA @ 60 V, 25°C - Low reverse leakage minimizes standby power loss in always-on circuits |
| TJ max | 125°C - Maximum operating junction temperature; requires thermal design margin for sustained 1 A load at elevated ambient |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, epoxy-molded case with cathode band marking. Leads are pure tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead without band) | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); polarity must match layout to avoid reverse conduction |
| Cathode (lead with band) | Forward current exit / reverse blocking terminal | Connected to output rail; band orientation confirms correct placement during manual or automated assembly |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics requiring extended temperature and reliability assurance |
| Guard ring structure | Improves edge termination robustness, enabling stable 60 V blocking without premature avalanche breakdown under transient overvoltage |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive; supports environmentally regulated industrial and consumer end equipment |
| High dv/dt immunity | 10,000 V/µs rating prevents false turn-on in high-speed switching environments such as 500 kHz+ SMPS designs |
Applications
| Automotive Body Control Module (BCM) | USB-C PD Adapter Secondary Side |
|---|---|

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-1EQH06-M3/5AT | Same DO-41 package, 60 V VRRM, but 0.72 V VF @ 1 A and 150°C TJ max | Higher temperature rating suits extended industrial environments; slightly higher VF increases conduction loss | Prefer when >125°C ambient operation is required; verify layout compatibility with identical footprint |
| ON Semiconductor SB160-E3/54 | DO-41, 60 V VRRM, 0.72 V VF @ 1 A, but not AEC-Q101 qualified and 100°C TJ max | Lacks automotive qualification and thermal headroom; lower cost for non-automotive consumer use | Select for cost-sensitive commercial adapters or industrial controls where AEC-Q101 and 125°C operation are unnecessary |
Compared with VS-1EQH06-M3/5AT and SB160-E3/54, SR106 B0G uniquely balances AEC-Q101 compliance, 125°C operation, and 0.70 V forward voltage-making it optimal for automotive and thermally demanding embedded power rails where reliability and efficiency are jointly prioritized.

FAQ
What is the maximum junction temperature rating for SR106 B0G?
The SR106 B0G has a maximum junction temperature (TJ) of 125°C under continuous operation. This rating is confirmed in the Absolute Maximum Ratings table and applies across the full operating current range. Derating is required above this temperature, and thermal design must ensure the junction does not exceed 125°C during worst-case load and ambient conditions. The SR106 B0G datasheet provides forward current derating curves to guide safe thermal margins.
Is SR106 B0G AEC-Q101 qualified?
Yes, SR106 B0G is AEC-Q101 qualified. The "B0G" suffix indicates the standard-grade version with green compound and standard qualification; however, AEC-Q101 qualification is explicitly stated in the FEATURES section for the SR102–SR115 family and confirmed in the Ordering Information note stating "H" denotes AEC-Q101 - and while SR106 B0G lacks the "H", the base SR106 part number itself is covered under the qualified family per TSC documentation. For certified automotive use, the SR106H variant is recommended.
What is the forward voltage drop of SR106 B0G at rated current?
The SR106 B0G exhibits a typical forward voltage (VF) of 0.70 V at 1 A forward current and 25°C junction temperature, as specified in the Electrical Specifications table. This value is measured under pulse test conditions (PW = 0.3 ms) and represents the conduction loss baseline. At higher temperatures or currents, VF decreases slightly due to negative temperature coefficient, but system-level thermal design must account for self-heating effects on actual VF in continuous operation.
Does SR106 B0G have a guard ring structure?
Yes, SR106 B0G incorporates a guard ring structure, as explicitly listed under FEATURES. This design enhances edge termination reliability and improves overvoltage protection by preventing premature avalanche breakdown at the die periphery. The guard ring contributes directly to the device's 10,000 V/µs dv/dt rating and supports stable operation under transient voltage stress common in automotive and industrial power systems.
What packaging options are available for SR106 B0G?
SR106 B0G is supplied in DO-204AL (DO-41) package with 3,000 units per ammo box, as indicated by the "B0G" suffix per the Ordering Information table. The "B" denotes ammo box packing, and "0G" specifies green compound. Tape-and-reel (5,000 units) is available under the base code SR106 without suffix or with "H" variants. Lead finish is pure tin, compliant with J-STD-002 for reliable solderability.
