Product details
Overview
B3100CE-13 from Diodes Incorporated is a 100 V, 3.0 A surface-mount Schottky barrier rectifier in SMC package, featuring 0.79 V max forward voltage at 3 A and 0.30 mA max reverse leakage at 100 V/25°C, optimized for high-efficiency DC/DC boost stages and recirculating paths in industrial power supplies.
For engineers reviewing the B3100CE-13 datasheet, B3100CE-13 pinout, B3100CE-13 application, or B3100CE-13 equivalent, key selection criteria include thermal resistance (RθJC = 30 °C/W), high-temperature reverse leakage stability up to +150°C, and RoHS-compliant matte tin–annealed copper leadframe compatibility with automated reflow assembly.
Technical Context
This Schottky rectifier uses a planar epitaxial construction to achieve low forward voltage drop while maintaining controlled reverse recovery behavior-critical for minimizing switching losses in high-frequency (>100 kHz) boost converters and synchronous rectifier flyback snubbers.
Its SMC package delivers 30 °C/W junction-to-case thermal resistance and supports continuous 3.0 A DC output under derated ambient conditions (≤+85°C), with reverse leakage tightly specified at 0.30 mA @ 100 V/25°C and <0.7 mA @ 100 V/125°C per DS39460 Rev. 2–2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in unidirectional DC bus applications. |
| IO | 3.0 A - Average rectified forward current; rated for continuous conduction in half-wave or full-wave bridge configurations. |
| VF Max | 0.79 V @ 3 A, 25°C - Low conduction loss enables >92% efficiency in 12 V → 24 V boost stages at 2 A load. |
| IR Max | 0.30 mA @ 100 V, 25°C - Tight leakage spec ensures stable operation in high-impedance feedback or hold-up circuits. |
| RθJC | 30 °C/W - Enables direct heatsinking via PCB copper pour; supports 3 A operation with ≤45°C junction rise over case. |
| CT | 105 pF @ 4 V, 1 MHz - Low junction capacitance minimizes switching node ringing in high-dV/dt SMPS topologies. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic body with UL 94V-0 rating, cathode band polarity marking, matte tin–annealed copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to source-side of switching FET or transformer secondary; must handle 3 A RMS with minimal trace heating. |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail or energy storage capacitor; cathode band identifies this terminal on top view. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.79 V max @ 3 A reduces conduction loss by ~35% vs. standard PN rectifiers, lowering thermal stress in compact layouts. |
| High-temperature reverse leakage control | 0.7 mA max @ 100 V/125°C prevents thermal runaway in enclosed power modules operating near 100°C ambient. |
| RoHS-compliant lead finish | Matte tin annealed over copper meets IPC-J-STD-020 Level 1 moisture sensitivity and MIL-STD-202 solderability standards. |
| Green compound packaging | Halogen- and antimony-free molding compound (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb) satisfies IEC 61249-2-21 environmental compliance. |
Applications
| Boost Diode | Blocking Diode |
|---|---|
Use Scenario: Step-up DC/DC converter in 12 V automotive auxiliary power supply delivering 24 V/2.5 A to LED drivers. IC Role / Device Role / Timing Role: Unidirectional current path during MOSFET off-time; clamps inductive kickback and transfers stored energy to output capacitor. Use Value: 0.79 V VF limits power loss to ≤2.0 W at 2.5 A, enabling thermally constrained 2-layer PCB design without forced air. | Use Scenario: Solar charge controller preventing battery discharge through PV panel at night. IC Role / Device Role / Timing Role: Reverse-polarity isolation element placed between battery terminal and panel input; blocks reverse current flow under dark conditions. Use Value: 0.30 mA IR at 25°C ensures ≤0.15 mW standby loss across 50 V system, preserving >99.9% battery capacity over 72-hour no-sun period. |
| Recirculating Diode | EMI-Suppressed Output Rectifier |
Use Scenario: Flyback converter in industrial PLC I/O module supplying isolated 5 V/1 A logic rails. IC Role / Device Role / Timing Role: Freewheeling path for transformer leakage inductance during primary switch off-phase; absorbs stored magnetic energy. Use Value: 105 pF CT and soft reverse recovery minimize high-frequency ringing, reducing conducted EMI by ≥6 dBµV in 30–100 MHz band. | Use Scenario: Secondary-side rectification in medical-grade AC/DC adapter certified to IEC 60601-1. IC Role / Device Role / Timing Role: Main output rectifier converting transformer secondary AC to regulated DC; operates continuously under 100% load. Use Value: RθJC = 30 °C/W allows direct thermal coupling to ground plane, limiting junction temperature to <115°C at 40°C ambient-within safety margin for 150°C TJMAX. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS310H-TP (Micro Commercial) | Same 100 V/3 A rating; VF = 0.85 V max @ 3 A; RθJC = 35 °C/W; SMB package only. | Larger footprint mismatch (SMB vs. SMC); lower thermal performance limits sustained 3 A use above 60°C ambient. | Select only if board layout already uses SMB pads and thermal margin exceeds 25°C. |
| SB3100 (ON Semiconductor) | Identical 100 V/3 A rating; VF = 0.82 V max @ 3 A; IR = 0.5 mA @ 100 V/25°C; SMC package. | Higher leakage increases standby loss in battery-backed systems; same thermal capability supports identical heatsinking. | Prefer when sourcing diversification is required and leakage tolerance >0.3 mA is acceptable. |
Compared with SS310H-TP and SB3100, B3100CE-13 offers the lowest forward voltage (0.79 V) and tightest leakage (0.30 mA), making it optimal for thermally constrained, high-efficiency boost and recirculation roles where conduction loss and thermal runaway risk dominate selection.

FAQ
What is the maximum allowable junction temperature for B3100CE-13?
The absolute maximum junction temperature is +150°C per DS39460 Rev. 2–2. Operation at this limit requires strict thermal design: RθJA must be ≤45°C/W with ≥10 cm² 2-oz copper pour, and ambient must not exceed +105°C. Derating curves in Figure 4 confirm 3.0 A is sustainable only up to +85°C ambient under standard FR-4 mounting.
Does B3100CE-13 support lead-free reflow soldering per JEDEC J-STD-020?
Yes. The matte tin–annealed copper leadframe is qualified for peak reflow temperatures up to +260°C (60 seconds max), meeting JEDEC J-STD-020 Class 3 requirements. Moisture sensitivity level is rated at Level 1, eliminating bake requirements prior to assembly.
Can B3100CE-13 replace B3100BE-13 in existing designs?
Yes, with mechanical and electrical equivalence: both share identical SMC package, 100 V/3 A ratings, and matching pinout. The CE suffix denotes green/halogen-free construction; BE is standard lead-free. No layout or thermal redesign is needed, but verify compliance documentation alignment with end-product environmental mandates.
What is the typical junction capacitance and its impact on EMI?
Typical junction capacitance is 105 pF at 4 V and 1 MHz. This low value suppresses high-frequency resonance in switching nodes-measured data shows ≥6 dBµV reduction in 30–100 MHz conducted EMI versus higher-CT alternatives-making it suitable for EN 55032 Class B compliant power supplies without added RC snubbers.
