Product details

Overview

MBR1630 from Diodes Incorporated is a 16A, 30V Schottky barrier rectifier in TO-220AC package, featuring low forward voltage drop (0.63 V @ 16A, 25°C), high surge capability (150 A, 8.3 ms), and transient protection via guard ring die construction. It is used in low-voltage, high-frequency inverters, freewheeling diode circuits, and polarity protection for DC power supplies.

For engineers reviewing the MBR1630 datasheet, MBR1630 pinout, MBR1630 application, or MBR1630 equivalent, key selection criteria include forward voltage at rated current, thermal resistance (1.5 °C/W junction-to-case), peak repetitive reverse voltage (30 V), surge rating, and RoHS-compliant tin-plated terminals.

Technical Context

The MBR1630 employs a Schottky barrier chip with integrated guard ring structure to suppress edge leakage and improve transient robustness. Its low V_F and fast switching enable high-efficiency operation in 60 Hz–100 kHz rectification without minority-carrier storage delay.

Designed for single-phase, half-wave rectification under resistive or inductive loads, it requires derating by 20% for capacitive loads. Thermal performance assumes mounting on an external heatsink, with junction temperature limited to −65°C to +150°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	30 V - Maximum non-repetitive reverse voltage the device blocks reliably without breakdown
I_O	16 A @ T_C = 125°C - Continuous average forward current sustainable with proper heatsinking
V_FM	0.63 V @ I_F = 16 A, T_C = 25°C - Low conduction loss enabling >92% efficiency in 5–12 V output rectifiers
I_FSM	150 A, 8.3 ms half-sine - Withstands inrush and short-circuit surges common in SMPS and motor drives
R_θJC	1.5 °C/W - Enables direct thermal path to heatsink; 10°C rise per 6.7 W dissipated at full load
C_T	450 pF @ 1 MHz, 4 V reverse - Low junction capacitance supports clean switching in high-frequency flyback and boost converters
I_RM	0.2 mA @ 25°C, rated V_R - Minimal leakage preserves battery life in always-on polarity protection circuits

Pinout & Package

Package: TO-220AC - 3-terminal, through-hole plastic case with isolated tab (pin 2), UL 94V-0 rated, 2.24 g weight, tin-plated leads solderable per MIL-STD-202 Method 208.

Pin 1 (Anode)	Anode connection	Main current entry point; electrically isolated from metal tab; connects to input/high-side node
Pin 2 (Cathode / Tab)	Cathode connection & thermal path	Electrically connected to cathode and exposed metal tab; must be insulated from chassis unless referenced to ground
Pin 3 (Anode)	Second anode terminal	Parallel anode path for reduced bond wire resistance; shares current with Pin 1 in high-current layout

Key Features

Applications

DC Power Supply Input Rectification

Freewheeling Diode in DC-DC Converters

Use Scenario: Single-phase AC input stage of 12 V/15 A industrial power supply with active PFC pre-regulator.

IC Role / Device Role / Timing Role: Output rectifier in post-PFC buck-derived stage; conducts during low-impedance discharge phase.

Use Value: 0.63 V V_F reduces conduction loss by 35% vs. comparable Si PN rectifier, lowering heatsink size by 40%.

Use Scenario: Synchronous buck converter output stage where body diode conduction occurs during high-side FET dead time.

IC Role / Device Role / Timing Role: Freewheeling path for inductor current when high-side MOSFET is off; operates at 100–500 kHz.

Use Value: 450 pF C_T and zero recovery charge minimize switching loss and EMI during commutation.

Polarity Protection in Battery-Powered Systems

Reverse Voltage Clamp in Automotive ECUs

Use Scenario: 24 V vehicle accessory module with hot-swap insertion and accidental reverse-battery connection risk.

IC Role / Device Role / Timing Role: Series-connected blocking diode placed between battery input and system rail; normally forward-biased.

Use Value: 0.2 mA I_RM at 25°C ensures <1 µA standby drain, preserving battery charge over 6-month storage.

Use Scenario: 12 V CAN bus node subjected to load-dump transients up to 40 V for 400 ms per ISO 7637-2.

IC Role / Device Role / Timing Role: Clamping diode across supply rail to shunt transient energy into bulk capacitor.

Use Value: Guard ring die construction withstands 150 A surge without parametric shift, ensuring functional safety compliance.

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-16CTH03-M3	Same 30 V V_RRM, 16 A I_O, but TO-220AB package with electrically isolated tab	Eliminates need for insulating washer; preferred where cathode must float from heatsink	Select when thermal interface design requires electrical isolation between cathode and heatsink
ON Semiconductor MBR1630CT	Center-tap dual-diode version in TO-220AB; each anode shares common cathode	Supports dual-output or center-tapped transformer rectification; not single-diode drop-in	Choose only for dual-anode configurations; not suitable for single-diode replacement

Compared with VS-16CTH03-M3 and MBR1630CT, the MBR1630 offers lowest V_F (0.63 V) and highest surge rating (150 A) in the TO-220AC form factor, making it optimal for cost-sensitive, high-reliability 16A rectification where cathode grounding is acceptable.

FAQ

What is the maximum junction temperature for continuous operation?

The MBR1630 has a specified operating junction temperature range of −65°C to +150°C. For continuous 16 A operation, case temperature must be held at or below 125°C using appropriate heatsinking; exceeding this derates average current per Fig. 1 in the datasheet.

Is the metal tab electrically connected to a specific pin?

Yes-the metal tab is internally connected to Pin 2 (cathode). It is not isolated and must be treated as a live terminal. Electrical isolation from the heatsink or chassis requires mica or polymer insulators and shoulder washers.

Can MBR1630 replace a standard silicon rectifier like 1N5408?

Yes, but only in low-voltage applications ≤30 V DC output. Unlike the 1N5408 (1000 V, 3 A), the MBR1630 offers higher current (16 A) and lower V_F, yet lacks high-voltage blocking-using it above 30 V risks catastrophic failure.

Does MBR1630 require a snubber circuit in high-dv/dt environments?

No snubber is required for typical 60 Hz or ≤500 kHz switching due to its guard ring die structure and 1000 V/s rated dv/dt. However, in systems exceeding 10 kV/µs (e.g., IGBT gate drive coupling), localized RC damping may still be advised per layout parasitics.
