Product details
Overview
B1100Q-13-F from Diodes Incorporated is a 100 V, 1.0 A high-voltage Schottky barrier rectifier in SMA package, featuring 0.79 V max forward voltage at 1.0 A and 0.5 mA max reverse leakage at rated VR, designed for polarity protection, DC-DC converter freewheeling, and AC-DC output rectification in automotive and industrial power supplies.
For engineers reviewing the B1100Q-13-F datasheet, B1100Q-13-F pinout, B1100Q-13-F application, or B1100Q-13-F equivalent, this part delivers verified AEC-Q101 qualification, RoHS-compliant lead-free plating, and thermal performance validated to +150°C junction temperature with 25°C/W junction-to-terminal thermal resistance.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient voltage immunity and suppress avalanche-induced failure during inductive switching events. Its low VF (0.79 V @ 1 A, 25°C) and low CT (80 pF @ 4 V, 1 MHz) support high-frequency operation in DC-DC converters up to several hundred kHz.
Rated for 30 A non-repetitive surge current (8.3 ms half-sine), it sustains repetitive operation under 1.0 A average forward current at terminal temperatures up to +125°C, with derating curves confirming usable current down to ~0.5 A at +150°C terminal temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; sets safe blocking margin in 48 V and 60 V DC bus applications. |
| IO | 1.0 A - Average forward rectified current at TT = +125°C; defines continuous conduction capability in compact power stages. |
| VF max | 0.79 V @ 1.0 A, 25°C - Low conduction loss enables >92% efficiency in 5–12 V output buck converters. |
| IR max | 0.5 mA @ 100 V, 25°C - Low leakage preserves battery hold-up time in always-on systems and reduces standby power. |
| CT | 80 pF @ 4 V, 1 MHz - Minimizes capacitive coupling noise and switching losses in high-frequency synchronous rectifiers. |
| RθJT | 25°C/W - Enables direct thermal path to PCB copper; supports 1.0 A operation with <25°C rise above ambient when mounted on ≥1 cm² 2-oz copper. |
| IFSM | 30 A @ 8.3 ms - Withstands inrush surges from bulk capacitor charging and motor startup transients without degradation. |

Applications
| Automotive Body Control Module (BCM) | Industrial 24 V DC-DC Converter |
|---|---|
Use Scenario: Reverse polarity protection on 12 V supply input to microcontroller-based lighting control unit. IC Role / Device Role / Timing Role: Unidirectional blocking diode preventing damage during battery jump-start misconnection. Use Value: 0.79 V VF limits voltage drop to <8% at 1 A, preserving MCU brown-out margin while eliminating fuse replacement. | Use Scenario: Freewheeling path in synchronous buck converter powering PLC I/O modules. IC Role / Device Role / Timing Role: Low-loss return path for inductor current during high-side FET off-time. Use Value: 80 pF capacitance and fast recovery minimize switching node ringing and EMI, easing EMC certification. |
| Telecom Power Shelf Rectification | Medical Patient Monitor Power Supply |
Use Scenario: Output rectification in isolated 48 V to 5 V flyback converter supplying FPGA core logic. IC Role / Device Role / Timing Role: Primary output rectifier handling continuous 1.0 A load with minimal conduction loss. Use Value: 25°C/W RθJT allows full-rated current with no heatsink on standard 2-layer PCB, reducing BOM cost. | Use Scenario: Blocking diode isolating backup battery from main 5 V rail during AC power loss. IC Role / Device Role / Timing Role: Standby isolation element preventing battery discharge into system load. Use Value: 0.5 mA IR max at 25°C ensures <1 µA standby drain per diode, extending battery runtime beyond 72 hours. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB1100-E3/52 | Same 100 V VRRM and 1.0 A IO, but VF = 0.85 V max @ 1 A; slightly higher conduction loss. | Less suitable for thermally constrained 125°C ambient environments due to higher VF-induced self-heating. | Select if legacy SB series footprint compatibility is required and 60 mV VF penalty is acceptable. |
| SS110H | 100 V VRRM, 1.0 A IO, VF = 0.83 V max @ 1 A; not AEC-Q101 qualified. | Not approved for automotive use; limited to commercial/industrial applications without PPAP or change control. | Choose only for cost-sensitive non-automotive designs where qualification documentation is unnecessary. |
Compared with SB1100-E3/52 and SS110H, B1100Q-13-F provides the lowest VF (0.79 V), AEC-Q101 qualification, and guaranteed 0.5 mA IR max-making it the sole choice for automotive-grade 1 A Schottky rectification where thermal headroom and supply-chain traceability are critical.

FAQ
Is B1100Q-13-F suitable for use in automotive under-hood applications?
Yes. It is AEC-Q101 qualified, manufactured in IATF 16949 certified facilities, and rated for TJ = –65°C to +150°C. Its guard ring die construction and 30 A IFSM rating meet transient requirements for engine control units and body electronics exposed to load dump and cold crank conditions.
What is the maximum PCB copper area needed to sustain 1.0 A at +125°C ambient?
With RθJT = 25°C/W and typical RθJA ≈ 120°C/W on 1 cm² 2-oz copper, sustaining 1.0 A at +125°C ambient requires terminal temperature ≤ +125°C. Using 25°C/W RθJT, a 25°C rise implies ≤ +150°C junction-achievable with ≥1 cm² thermal pad and minimal trace length, no additional heatsink required.
Does B1100Q-13-F have a specified reverse recovery time (trr)?
No-Schottky diodes are majority-carrier devices with no minority-carrier storage delay. The B1100Q-13-F exhibits effectively zero reverse recovery time, confirmed by its lack of trr specification in DS38613 and typical fast-switching behavior shown in Fig. 5 reverse characteristic curves.
Can B1100Q-13-F replace B190Q-13-F in an existing design?
Yes, with design verification. Both share identical SMA package, pinout, and thermal characteristics, but B1100Q-13-F offers 10 V higher VRRM (100 V vs. 90 V) and same VF/IR. Ensure reverse voltage stress remains within 100 V; no layout or thermal changes are needed for drop-in substitution.
