Product details
Overview
KBP201G from Diodes Incorporated is a 2.0A standard recovery bridge rectifier in KBP package, rated for 100V peak repetitive reverse voltage (VRRM), 1.1V max forward voltage at 2A, and 5µA max reverse leakage at 25°C. It delivers reliable AC-to-DC conversion in offline power supplies, battery chargers, and industrial control power stages.
For engineers reviewing the KBP201G datasheet, KBP201G pinout, KBP201G application, or KBP201G equivalent, key selection criteria include VRRM margin for line surge, thermal resistance (RθJC = 14°C/W), IFSM = 65A surge rating, and UL recognition for safety-critical designs.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a common anode–common cathode configuration, enabling bidirectional AC input rectification with inherent polarity correction. Its glass-passivated die construction ensures stable junction behavior under thermal cycling and humidity stress.
The device operates across –55°C to +150°C junction temperature range and requires derating to 1.6A for capacitive loads. Thermal performance is defined relative to a 75mm × 75mm × 1.6mm copper heatsink, with RθJA = 40°C/W in free-air conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage the bridge withstands without breakdown; sets minimum insulation margin for 120VAC input designs. |
| IF(AV) | 2.0 A - Average rectified output current at TC = +105°C; defines continuous DC load capability with proper heatsinking. |
| VF Max | 1.1 V @ 2A - Forward voltage per diode element; determines conduction loss (2.2V total bridge drop) and thermal dissipation at full load. |
| IFSM | 65 A - Non-repetitive surge current (8.3ms half-sine); supports inrush current handling during cold start of SMPS or linear supplies. |
| IR Max | 5 µA @ 25°C - Reverse leakage per element at rated VRRM; critical for low-power standby circuits and high-impedance bias networks. |
| RθJC | 14 °C/W - Junction-to-case thermal resistance; enables direct mounting to heatsinks for thermal management in compact power modules. |
Pinout & Package
Package: KBP - Molded plastic case (UL 94V-0), 4-terminal single-in-line (SIP) configuration with tin-plated leads. Dimensions: 14.5mm × 10.4mm × 4.0mm (L × E × z), weight ≈ 1.52g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| ~ (AC2) | AC Input Terminal 2 | Other side of AC input; completes full-wave bridge input path with AC1. |
| + (DC+) | Positive DC Output | Anode of internal upper diodes; delivers rectified positive output to filter capacitor or regulator stage. |
| – (DC–) | Negative DC Output / Common Return | Cathode of internal lower diodes; serves as system ground reference and return path for DC load current. |

| UL Recognized Component (E95060) | Meets UL 60747-4 and CSA C22.2 No. 22.2 standards; eliminates need for end-equipment retesting of rectifier subassembly. |
| Lead-free & RoHS compliant | Meets EU RoHS 3 (2015/863/EU); compatible with lead-free reflow profiles and environmental compliance programs. |
Applications
| AC-DC Power Adapters | Industrial Motor Control Power Supplies |
|---|---|
Use Scenario: 120VAC input conversion for wall-mounted USB-C PD adapters and low-power IoT power bricks. IC Role / Device Role / Timing Role: Primary rectification stage converting mains AC to unregulated DC bus prior to buck or flyback regulation.

IC Role / Device Role / Timing Role: Safety-critical rectifier in Class I grounded appliances requiring UL recognition and flame-retardant packaging. Use Value: UL E95060 listing and 94V-0 molded case satisfy end-product safety certification without additional barrier materials or spacing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K (ON Semiconductor) | Same KBP package, 100V VRRM, but VF = 1.05V @ 2A and IFSM = 60A; slightly lower conduction loss, reduced surge margin. | Preferred where thermal budget is tighter but surge events are infrequent (e.g., consumer electronics). | Select GBU2K if optimizing for efficiency over surge robustness; verify layout clearance for alternate marking orientation. |
| KBL201 (Diodes Inc.) | Same electrical specs, but KBL package (4.5mm height vs KBP's 4.0mm); identical pinout, higher creepage distance due to longer body. | Better suited for high-humidity or pollution degree 3 environments requiring extended surface tracking paths. | Choose KBL201 when enhanced insulation coordination is required; note taller profile may affect board clearance. |
Compared with KBP201G, GBU2K trades 5A lower surge rating for marginally better conduction efficiency, while KBL201 retains identical performance but improves mechanical insulation integrity-making KBP201G optimal for cost-sensitive, space-constrained, UL-mandated applications.

FAQ
What is the maximum operating temperature for KBP201G?
KBP201G has a specified junction temperature range of –55°C to +150°C. Its average rectified current rating of 2.0A applies only at TC = +105°C; operation above this case temperature requires linear derating per Figure 1 in DS21205, reaching zero current at +150°C case temperature.
Is KBP201G suitable for use in automotive applications?
KBP201G is not AEC-Q200 qualified and lacks PPAP documentation or IATF 16949 manufacturing evidence in its public datasheet. While it meets basic environmental ratings, Diodes explicitly states that automotive-grade variants require direct engagement with their sales team for change-controlled, qualified parts.
How does the KBP package differ from KBPC or GBU packages?
KBP is a 4-pin single-in-line (SIP) molded plastic package (14.5 × 10.4 × 4.0 mm), distinct from KBPC (larger, 20mm length) and GBU (shorter body, 10mm length, different lead pitch). Pinout is identical across all three, but mechanical fit, thermal mass, and creepage distances differ-requiring layout verification before substitution.
Can KBP201G replace KBP2005G in a design?
No-KBP2005G is rated for 50V VRRM, while KBP201G is rated for 100V. Substituting KBP201G into a 50V-design may cause excessive conduction loss and thermal stress due to higher VF and junction capacitance; conversely, using KBP2005G in a 100V circuit risks reverse breakdown during line surges.
