Product details
Overview
MSX1PD-M3/89A from Vishay General Semiconductor is a surface-mount ESD-capable Schottky rectifier in MicroSMP (DO-219AD) package, rated for 200 V repetitive peak reverse voltage, 1.0 A average forward current, and 18 A non-repetitive surge current. It delivers 0.9 V forward voltage at 1.0 A and 125 °C, with 960 ns typical reverse recovery time and 5 pF junction capacitance - used for polarity and rail-to-rail protection in automotive power rails and industrial DC inputs.
For engineers reviewing the MSX1PD-M3/89A datasheet, MSX1PD-M3/89A pinout, MSX1PD-M3/89A application, or MSX1PD-M3/89A equivalent, key selection criteria include its AEC-Q101 qualification (HM3 variant), MSL Level 1 rating, 175 °C max junction temperature, low-profile 0.65 mm height, and ESD immunity exceeding 8 kV per HBM (JESD22-A114) and 15 kV per IEC 61000-4-2 air discharge.
Technical Context
This device is a single-die, oxide planar Schottky rectifier optimized for low forward voltage and fast switching in space-constrained DC power paths. Its MicroSMP package enables automated placement and supports high-density PCB layouts while maintaining thermal resistance of 110 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead).
Designed for commercial, industrial, and automotive environments, it meets J-STD-020 MSL Level 1 (260 °C reflow peak), passes JESD201 Class 2 whisker testing, and exhibits <1.0 μA reverse leakage at 25 °C and <50 μA at 125 °C under rated VRRM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum reverse blocking capability for 24 V–48 V system rail protection |
| IF(AV) | 1.0 A - continuous DC current handling at TA = 25 °C with derating above 25 °C |
| VF @ 1.0 A, 125 °C | 0.9 V - low conduction loss enabling efficient operation in thermally stressed environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-MR12020-M3 | Higher VRRM (200 V same), but larger SMA package (2.5 mm × 1.5 mm × 1.2 mm), higher RθJA (140 °C/W), no AEC-Q101 option | Less suitable for ultra-low-profile or automotive-qualified designs; better for manual assembly or legacy layouts | Select when board space allows larger footprint and AEC-Q101 is not required |
| ON Semiconductor SB120 | Same VRRM (200 V), same IF(AV) (1.0 A), but DO-214AA package (4.2 mm × 2.5 mm), VF = 0.95 V @ 1.0 A, 25 °C only | Higher profile and thermal resistance limits use in thermally dense or automotive under-hood locations | Choose for cost-sensitive commercial applications where MicroSMP placement equipment is unavailable |
Compared with VS-MR12020-M3 and SB120, MSX1PD-M3/89A offers the smallest footprint, lowest height, best thermal performance in its class, and unique AEC-Q101 qualification - making it optimal for next-generation automotive and space-constrained industrial power interfaces.

FAQ
What is the maximum junction temperature rating for MSX1PD-M3/89A?
The MSX1PD-M3/89A has a maximum junction temperature (TJ) of +175 °C, verified per Vishay's thermal characterization and validated across its full operating range. This rating enables reliable operation in under-hood automotive environments and high-temperature industrial enclosures. Derating curves in the datasheet confirm 1.0 A IF(AV) is maintained up to 125 °C ambient with appropriate PCB copper area, and the device remains functional beyond that with reduced current capacity. The 175 °C limit is integral to its AEC-Q101 qualification scope.
Does MSX1PD-M3/89A meet automotive qualification standards?
MSX1PD-M3/89A itself carries the M3 suffix, indicating halogen-free and RoHS compliance but not AEC-Q101 qualification. However, its automotive-grade variant MSX1PDHM3/89A is explicitly AEC-Q101 qualified per the Vishay datasheet. Engineers selecting MSX1PD-M3/89A for automotive use must verify whether their design requires formal qualification - if so, the HM3 version is mandatory. Both share identical electrical specs, package, and marking code "XD".
What does the "89A" in MSX1PD-M3/89A indicate?
The "89A" in MSX1PD-M3/89A is Vishay's preferred package code denoting a 7-inch diameter plastic tape-and-reel delivery format containing 4500 units per reel. It specifies packaging configuration only - not electrical or thermal differences. This code appears in ordering information tables and is used by automated pick-and-place machines for reel setup. No functional or parametric variation exists between MSX1PD-M3/89A and other M3-suffix variants using different reel codes (e.g., 89B or 89C).
How does the ESD performance of MSX1PD-M3/89A compare to standard rectifiers?
MSX1PD-M3/89A provides >8 kV human-body-model (HBM) ESD immunity per JESD22-A114 and >15 kV air-discharge immunity per IEC 61000-4-2 - significantly exceeding typical Schottky rectifiers (<2 kV HBM). This is achieved through proprietary junction passivation and layout design. As a result, MSX1PD-M3/89A can serve dual roles: rectification and system-level ESD protection - reducing or eliminating the need for discrete TVS diodes in 12 V/24 V power rails and interface lines.
What is the thermal resistance from junction to lead (RθJL) for MSX1PD-M3/89A?
The thermal resistance from junction to lead (RθJL) for MSX1PD-M3/89A is 30 °C/W, measured at the cathode terminal per Vishay's test conditions. This value reflects direct conduction from die to cathode pad and is critical for estimating local temperature rise when the cathode is connected to a large copper pour. Unlike RθJA (110 °C/W), RθJL is less dependent on board layout and enables accurate thermal modeling of high-current pulse events where ambient convection is negligible.
