Product details
Overview
B2100Q-13-F from Diodes Incorporated is a 100 V, 2.0 A surface-mount Schottky barrier rectifier in SMB package, featuring 0.79 V max forward voltage at 2.0 A and 7 µA max reverse leakage at 25°C, optimized for polarity protection and freewheeling in low-voltage DC/DC converters and automotive power modules.
For engineers reviewing the B2100Q-13-F datasheet, B2100Q-13-F pinout, B2100Q-13-F application, or B2100Q-13-F equivalent, key selection criteria include peak repetitive reverse voltage (100 V), average forward current (2.0 A), thermal resistance (15 °C/W), surge rating (50 A), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient immunity and supports high-frequency switching with 75 pF typical junction capacitance at 4 V reverse bias. Its low VF enables reduced conduction loss in 12 V–48 V input power rails.
The device operates across –65°C to +150°C, with thermal resistance of 15 °C/W (junction-to-terminal), enabling stable performance under sustained 2.0 A load at terminal temperatures up to +125°C per derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - blocks up to 100 V DC or peak AC reverse voltage without breakdown |
| IO | 2.0 A - continuous average forward current capability at TT = +125°C |
| VF Max | 0.79 V @ 2.0 A, 25°C - limits conduction loss to ≤1.58 W per diode in series-switched paths |
| IR Max | 7.0 µA @ 100 V, 25°C - ensures minimal standby power loss in battery-backed systems |
| IFSM | 50 A - withstands single half-sine surge events (8.3 ms) during inductive turn-off |
| RθJT | 15 °C/W - enables direct thermal coupling to PCB copper for passive cooling |
| CT | 75 pF @ 4 V, 1 MHz - supports operation up to ~10 MHz switching in snubberless flyback designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB2100-E3/52 (Vishay) | Same SMB package, 100 V/2.0 A, but VF = 0.85 V max @ 2 A; no AEC-Q101 qualification | Not approved for automotive use; suitable for industrial/commercial only | Select when AEC-Q101 is not required and higher VF is acceptable |
| SS210H (ON Semiconductor) | SMB package, 100 V/2.0 A, VF = 0.82 V max @ 2 A; AEC-Q101 qualified but IR = 10 µA @ 25°C | Higher leakage may impact ultra-low-power battery hold-up time | Select when broader temperature range validation is needed, accepting 3 µA higher IR |
Compared with SB2100-E3/52 and SS210H, B2100Q-13-F delivers the lowest VF (0.79 V) among AEC-Q101-qualified 2 A/100 V Schottkys and maintains the tightest IR spec (7 µA), making it optimal for thermally constrained automotive and medical applications demanding efficiency and low standby loss.

FAQ
What is the maximum junction temperature for continuous operation?
The B2100Q-13-F has an operating junction temperature range of –65°C to +150°C. Continuous operation at full 2.0 A average current requires terminal temperature ≤+125°C per the derating curve; above that, current must be linearly reduced to maintain TJ ≤+150°C.
Is this diode suitable for synchronous rectification?
No - the B2100Q-13-F is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET driver. It functions as a unidirectional conduction device only; synchronous rectification requires active gate control of a MOSFET.
Does the SMB package support automated optical inspection (AOI)?
Yes - the SMB package features defined cathode band marking and consistent body dimensions (3.30–3.94 mm width, 5.00–5.59 mm length), enabling reliable AOI detection of placement orientation and solder joint quality in high-volume SMT lines.
How does the guard ring construction improve reliability?
The guard ring die structure reduces electric field crowding at the PN junction periphery, increasing resistance to avalanche-induced degradation and improving survivability during repetitive 50 A surge events and ESD transients per IEC 61000-4-2 Level 4.
