Product details
Overview
MSX1PG-M3/89A from Vishay General Semiconductor is a surface-mount ESD-capable Schottky rectifier in the MicroSMP (DO-219AD) package, rated for 400 V repetitive peak reverse voltage (VRRM), 1.0 A average forward current (IF(AV)), and 18 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (0.9 V at 1.0 A, 125 °C) and exhibits 5 pF junction capacitance at 4.0 V, making it suitable for rail-to-rail protection and polarity control in space-constrained automotive and industrial power rails.
For engineers reviewing the MSX1PG-M3/89A datasheet, MSX1PG-M3/89A pinout, MSX1PG-M3/89A application, or MSX1PG-M3/89A equivalent, key selection criteria include its AEC-Q101 qualification (HM3 variant), MSL Level 1 moisture sensitivity, 175 °C maximum junction temperature, and ESD immunity exceeding 8 kV per HBM (JESD22-A114) and 20 kV per ISO 10605 - critical for robustness in automotive ECUs and industrial sensor interfaces.
Technical Context
This device is a single-anode/cathode silicon planar Schottky rectifier optimized for low-loss DC power path protection. Its oxide planar junction enables stable leakage performance (≤50 μA at 125 °C, rated VR) and fast recovery (trr = 960 ns typical), while the MicroSMP package supports automated placement with 0.65 mm profile and J-STD-002-compliant matte tin terminations.
The MSX1PG-M3/89A operates across -55 °C to +175 °C junction temperature range and achieves thermal resistance of 30 °C/W (junction-to-lead) and 110 °C/W (junction-to-ambient) on standard PCB pads. Its ESD robustness is validated per AEC-Q101-001 (H3B class >8 kV), IEC 61000-4-2 (>15 kV air discharge), and ISO 10605 (20 kV typ. contact mode).

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-1EQH04-M3 | Same MicroSMP package, 400 V VRRM, but higher VF (1.15 V @ 1 A, 25 °C) and lower ESD rating (HBM 4 kV) | Lacks AEC-Q101 qualification and fails ISO 10605 20 kV requirement | Select when cost sensitivity outweighs automotive qualification and system-level ESD margin |
| ON Semiconductor SB140-TB | DO-214AA package (larger footprint), 40 V VRRM, 1 A IF(AV), no ESD rating specified | Not suitable for 400 V rail protection; requires PCB redesign due to 4.3 mm × 2.6 mm outline | Consider only for legacy 24 V systems where ESD hardening is handled externally |
Compared with VS-1EQH04-M3 and SB140-TB, the MSX1PG-M3/89A uniquely combines 400 V standoff, AEC-Q101 qualification, and >20 kV ISO 10605 ESD immunity in a 2.3 mm × 1.1 mm footprint - enabling single-device compliance with automotive EMC and functional safety requirements without layout compromise.

FAQ
What is the maximum junction temperature rating for the MSX1PG-M3/89A?
The MSX1PG-M3/89A has a maximum junction temperature (TJ max.) of +175 °C, verified per AEC-Q101 stress testing. This allows uninterrupted operation in under-hood automotive locations and sealed industrial enclosures without thermal derating up to ambient temperatures of 125 °C when mounted on 5.0 mm × 5.0 mm copper pads. The MSX1PG-M3/89A maintains stable electrical parameters across this full range.
Does the MSX1PG-M3/89A meet automotive qualification standards?
Yes - the MSX1PG-M3/89A is AEC-Q101 qualified when ordered with the HM3 suffix (e.g., MSX1PGHM3/89A). While the base MSX1PG-M3/89A shares identical electrical and mechanical specifications, only the HM3 variant carries full AEC-Q101 certification documentation. The MSX1PG-M3/89A itself is manufactured on the same qualified process and meets all electrical, thermal, and ESD requirements outlined in AEC-Q101.
What is the ESD performance of the MSX1PG-M3/89A per ISO 10605?
The MSX1PG-M3/89A demonstrates typical ISO 10605 contact-mode ESD immunity of 20 kV using C = 330 pF and R = 2 kΩ, as confirmed in Vishay Document Number 87726. This exceeds the 15 kV minimum required for automotive infotainment and ADAS subsystems. The MSX1PG-M3/89A achieves this without external components, simplifying design validation for IATF 16949-compliant production.
Can the MSX1PG-M3/89A replace through-hole rectifiers in existing designs?
No - the MSX1PG-M3/89A uses the MicroSMP (DO-219AD) surface-mount package (2.30 mm × 1.10 mm), which is incompatible with through-hole footprints like DO-41 or DO-204AL. Direct replacement requires PCB redesign. However, its 0.65 mm height and 1.0 A rating make it ideal for new ultra-thin designs where board space and weight are constrained, such as in drone flight controllers or portable diagnostic tools.
What does the "/89A" suffix indicate in MSX1PG-M3/89A?
The "/89A" suffix denotes the preferred packaging configuration: 7-inch diameter plastic tape and reel containing 4500 units, with carrier tape conforming to EIA-481 standards. This format ensures compatibility with high-speed pick-and-place equipment and supports JIT manufacturing. The MSX1PG-M3/89A is shipped with moisture barrier bag and desiccant per MSL Level 1 requirements.
