Product details
Overview
MSX1PJ-M3/89A from Vishay General Semiconductor is a surface-mount Schottky rectifier in the eSMP® MicroSMP (DO-219AD) package, rated for 600 V repetitive peak reverse voltage, 1.0 A average forward current, and 18 A non-repetitive surge current. It features low forward voltage drop (0.9 V at 1.0 A, 125 °C), 960 ns typical reverse recovery time, and ESD immunity exceeding 8 kV per HBM (JESD22-A114). It is used for rail-to-rail polarity protection in automotive power modules.
For engineers reviewing the MSX1PJ-M3/89A datasheet, MSX1PJ-M3/89A pinout, MSX1PJ-M3/89A application, or MSX1PJ-M3/89A equivalent, key selection criteria include its 600 V VRRM, MicroSMP footprint compatibility with space-constrained PCBs, AEC-Q101 qualification status (via HM3 variant), thermal resistance of 30 °C/W (junction-to-lead), and ESD robustness per ISO 10605 (20 kV typ.) and IEC 61000-4-2 (air discharge >15 kV).
Technical Context
This device is a single-die, oxide planar junction Schottky rectifier optimized for high-voltage commercial and automotive applications where low leakage and fast switching are required. Its 600 V rating enables use in 48 V and 60 V DC bus protection, while its 175 °C maximum junction temperature supports under-hood deployment without derating.
The MicroSMP (DO-219AD) package provides a 0.65 mm profile and matte tin-plated terminals compliant with J-STD-002 and JESD22-B102. Thermal performance is characterized with RθJA = 110 °C/W and RθJL = 30 °C/W on 5.0 mm × 5.0 mm copper pads, enabling efficient heat transfer to the PCB.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-MBR1660CT-M3 | TO-220AB package, dual common-cathode configuration, 600 V, 8 A per die | Higher current, through-hole mounting, no ESD qualification | Select when higher surge capacity and heatsink attachment are required; not suitable for space-constrained SMT layouts |
| ON Semiconductor SBVR6060 | MicroSMP package, 600 V, 1.0 A, VF = 0.92 V @ 1 A, but only JESD22-A114 HBM = 4 kV | Lacks AEC-Q101 and ISO 10605 qualification; lower ESD immunity | Acceptable for commercial-grade applications where ESD stress is controlled; not recommended for automotive or harsh industrial environments |
Compared with VS-MBR1660CT-M3 and SBVR6060, MSX1PJ-M3/89A uniquely combines 600 V rating, MicroSMP footprint, >8 kV HBM ESD, and AEC-Q101-ready qualification-making it the only option among the three qualified for automotive under-hood polarity protection without layout or thermal redesign.

FAQ
What is the maximum junction temperature rating for MSX1PJ-M3/89A?
The MSX1PJ-M3/89A has a maximum junction temperature (TJ) of +175 °C, verified per the Vishay datasheet revision 04-Aug-2020. This rating allows the MSX1PJ-M3/89A to operate reliably in under-hood automotive environments and near high-power converters without thermal throttling or derating below 1.0 A at ambient temperatures up to 125 °C.
Is MSX1PJ-M3/89A AEC-Q101 qualified?
No-MSX1PJ-M3/89A is not AEC-Q101 qualified. The AEC-Q101-qualified version is the MSX1PJHM3/89A, which carries the HM3 suffix and includes full automotive-grade testing and traceability. The MSX1PJ-M3/89A is commercial-grade, RoHS-compliant, and halogen-free, but lacks the automotive qualification documentation required for Tier 1 automotive programs.
What does the "89A" in MSX1PJ-M3/89A indicate?
The "89A" in MSX1PJ-M3/89A is Vishay's preferred package code denoting a 7-inch diameter plastic tape-and-reel delivery format containing 4500 units. It specifies packaging configuration only-not electrical or thermal differences-and applies identically to both MSX1PJ-M3/89A and MSX1PJHM3/89A variants.
How does the ESD performance of MSX1PJ-M3/89A compare to standard Schottky diodes?
The MSX1PJ-M3/89A delivers >8 kV HBM (JESD22-A114 Class 3B), >400 V MM (JESD22-A115 Class C), and >15 kV air-discharge per IEC 61000-4-2-exceeding most standard Schottky diodes, which typically offer ≤4 kV HBM. This enhanced ESD robustness is achieved via proprietary junction design and passivation, making the MSX1PJ-M3/89A suitable for unshielded board-level interfaces without additional protection circuitry.
What is the thermal resistance from junction to lead (RθJL) for MSX1PJ-M3/89A?
The thermal resistance from junction to lead (RθJL) for MSX1PJ-M3/89A is 30 °C/W, measured at the cathode band terminal on a PCB with 5.0 mm × 5.0 mm copper pad areas. This value enables effective heat conduction from the die directly into the PCB plane, supporting sustained 1.0 A operation without external heatsinking when layout guidelines are followed.
