Product details
Overview
MBRS30H45CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 30A average forward current, 45V repetitive peak reverse voltage, and 220A non-repetitive surge current; it delivers low forward voltage (0.70 V typ. @ 15 A, 25°C) and operates up to 175°C junction temperature, enabling high-efficiency DC/DC conversion in automotive lighting and battery protection circuits.
For engineers reviewing the MBRS30H45CTH datasheet, MBRS30H45CTH pinout, MBRS30H45CTH application, or MBRS30H45CTH equivalent, key selection criteria include its AEC-Q101 qualification, 1.5°C/W junction-to-case thermal resistance, dual-common-cathode configuration, moisture sensitivity level 1 rating, and guard-ring–enhanced dv/dt capability of 10,000 V/µs.
Technical Context
This dual-die Schottky rectifier integrates two independent anodes sharing a common cathode terminal, supporting synchronous rectification or freewheeling in half-bridge topologies. Its low VF and high IFSM enable minimal conduction loss and robust transient handling in 12 V/24 V automotive power rails.
The device uses a guard ring structure to sustain high dv/dt stress without snapback, and its TO-263AB package provides low RθJC (1.5°C/W) and compatibility with automated SMT placement-critical for high-volume car lighting and infotainment power modules.

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-30CPH045 | Same TO-263AB package, 30 A/45 V rating, but not AEC-Q101 qualified; VF = 0.72 V max @ 30 A, 25°C | Lacks automotive qualification; suitable for industrial DC/DC where AEC compliance is not mandated | Select VS-30CPH045 only if automotive qualification is unnecessary and cost sensitivity outweighs long-term reliability requirements |
| ON Semiconductor MBR30H45CT | Identical electrical specs and TO-263AB package; AEC-Q101 qualified; marking code differs (MBR vs MBRS), same dual-common-cathode pinout | Drop-in replacement in most designs; minor differences in thermal impedance (RθJC = 1.6°C/W vs 1.5°C/W) | MBR30H45CT is a functionally equivalent, AEC-Q101–qualified alternative with near-identical thermal and electrical behavior |
Compared with VS-30CPH045, MBRS30H45CTH adds AEC-Q101 validation and tighter thermal resistance; versus MBR30H45CT, it offers marginally better RθJC and identical automotive suitability-making MBRS30H45CTH optimal for space-constrained, high-reliability automotive power stages.

FAQ
What is the pin configuration of MBRS30H45CTH?
The MBRS30H45CTH uses a 3-terminal TO-263AB (D2PAK) package with two anodes (A1, A2) and one common cathode (K). Pin 1 is A1, Pin 2 is K (tab), and Pin 3 is A2-verified from TSC's official package outline drawing and marking diagram. This dual-common-cathode layout supports parallel or interleaved operation in multi-phase converters.
Is MBRS30H45CTH suitable for reverse battery protection?
Yes, MBRS30H45CTH is explicitly recommended for reverse battery protection in automotive systems. Its 45 V VRRM provides margin above 24 V truck battery transients, and its 220 A IFSM handles cranking surges per ISO 16750-2. The device's low VF also limits power dissipation during normal forward conduction in the protection path.
Does MBRS30H45CTH require a moisture bake before reflow?
No, MBRS30H45CTH has moisture sensitivity level (MSL) 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions and placed directly into reflow without baking. This simplifies SMT line integration and eliminates yield risk from moisture-induced popcorning.
What is the maximum junction temperature rating for MBRS30H45CTH?
The MBRS30H45CTH is rated for a maximum junction temperature of +175°C, confirmed in the Absolute Maximum Ratings table. This rating is validated across temperature cycling, HTGB, and HTRB tests per AEC-Q101, making MBRS30H45CTH suitable for under-hood applications such as engine control units and headlamp drivers.
How does the guard ring in MBRS30H45CTH improve reliability?
The guard ring in MBRS30H45CTH suppresses edge breakdown and prevents parasitic thyristor activation during high dv/dt events. It enables the device to sustain 10,000 V/µs without snapback-critical for noise immunity in fast-switching automotive inverters where gate drive ringing could otherwise trigger unintended conduction.
