Product details
Overview
MSX1PBHM3/89A from Vishay General Semiconductor is a surface-mount ESD-capable Schottky rectifier in MicroSMP (DO-219AD) package, rated for 100 V repetitive peak reverse voltage, 1.0 A average forward current, and 18 A non-repetitive surge current. It delivers low forward voltage drop (0.9 V at 1.0 A, 125 °C), operates up to 175 °C junction temperature, and is AEC-Q101 qualified for automotive polarity protection.
For engineers reviewing the MSX1PBHM3/89A datasheet, MSX1PBHM3/89A pinout, MSX1PBHM3/89A application, or MSX1PBHM3/89A equivalent, key selection factors include its ESD immunity (>8 kV HBM per JESD22-A114), ultra-low profile (0.65 mm height), halogen-free RoHS-compliant construction, and MicroSMP footprint compatibility with automated placement.
Technical Context
This device is a single-anode/cathode Schottky rectifier with oxide planar chip junction, optimized for low VF and low IR across commercial and automotive temperature ranges. Its ESD robustness meets AEC-Q101-001 (H3B class), IEC 61000-4-2 (air discharge >15 kV), and ISO 10605 (20 kV typical).
Thermal performance is defined by RθJA = 110 °C/W and RθJL = 30 °C/W (measured at cathode band terminal), supporting high-density PCB layouts with 5.0 mm × 5.0 mm copper pads. Reverse recovery time is 960 ns (typical), and junction capacitance is 5 pF at 4.0 V, 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum reverse blocking capability without breakdown under repetitive conditions. |
| IF(AV) | 1.0 A - Continuous DC forward current rating at TA = 25 °C with derating above 25 °C. |

Pinout & Package
MicroSMP (DO-219AD) is a 2-terminal surface-mount package with anode and cathode on opposite ends of the molded body; cathode identified by a color band. The device has no internal leads - terminals are formed by metallized end caps.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to positive supply or protected rail; must be routed with adequate current-carrying trace width. |
| Cathode (K) | Forward current exit / reverse blocking terminal | Marked with color band; serves as reference node for polarity protection and ESD clamping paths. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS power rails. |
| ESD immunity >8 kV (HBM) | Reduces need for external TVS diodes in I/O and power input stages of connected devices. |
| 0.65 mm profile | Enables ultra-thin designs in space-constrained consumer electronics and portable modules. |
| Oxide planar junction | Ensures stable leakage current (<1.0 µA at 25 °C) and predictable VF across temperature and lifetime. |
| Halogen-free & RoHS-compliant | Meets global environmental compliance requirements for industrial and automotive OEMs. |
Applications
| Automotive Power Rail Protection | USB-C Port Polarity Guard |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from reverse-battery connection during service or jump-start. IC Role / Device Role / Timing Role: Unidirectional polarity protection rectifier placed in series with main power input. Use Value: Prevents damage to downstream PMICs and microcontrollers while adding only 0.9 V conduction loss at full load. |
Use Scenario: Ensuring correct VBUS polarity in dual-role USB-C receptacles where plug orientation is undefined. IC Role / Device Role / Timing Role: Series-blocking diode on VBUS path to enforce unidirectional current flow. Use Value: Eliminates risk of back-powering host ports; low VF minimizes voltage drop across 5 V ±5% tolerance window. |
| Industrial Sensor Node Input Clamp | Smart Home IoT Power Sequencing |
Use Scenario: Safeguarding 3.3 V or 5 V sensor interface inputs against accidental reverse-wiring or ESD events. IC Role / Device Role / Timing Role: Front-end polarity and ESD protection element before LDO or signal conditioning circuitry. Use Value: Combines rail-to-rail clamping and reverse blocking in one device, reducing BOM count and board area. |
Use Scenario: Controlling power-up sequence between primary and auxiliary rails in battery-backed smart thermostats or hubs. IC Role / Device Role / Timing Role: Isolation diode enabling controlled voltage ramp and preventing backfeed between domains. Use Value: Enables clean power sequencing without active control logic; 175 °C rating supports sealed enclosure thermal profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB1100-TB-E3/5AT | 100 V, 1.0 A, VF = 0.85 V @ 1 A (25 °C); not AEC-Q101 qualified; DO-214AA package (higher profile, larger footprint). | Lacks automotive qualification and ESD certification; suitable for commercial-only designs with less stringent reliability requirements. | Choose when cost sensitivity outweighs automotive compliance and board space is not constrained. |
| SS12HM3/89A | 200 V, 1.0 A, VF = 1.05 V @ 1 A (125 °C); same MicroSMP package and AEC-Q101 qualification; higher VRRM but higher VF. | Supports higher-voltage rails (e.g., 24 V industrial systems) but incurs greater conduction loss at 12 V. | Choose when reverse voltage margin >100 V is required and thermal budget allows higher VF. |
Compared with SB1100-TB-E3/5AT, MSX1PBHM3/89A offers automotive qualification and lower profile; compared with SS12HM3/89A, it provides lower VF at 100 V rating-enabling better efficiency in 12 V automotive subsystems without sacrificing reliability or footprint.

FAQ
What is the maximum operating temperature for MSX1PBHM3/89A?
The MSX1PBHM3/89A has a maximum junction temperature (TJ max.) of 175 °C, validated per AEC-Q101 stress testing. This enables reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 105 °C. Derating curves in the datasheet define safe current limits above 25 °C ambient.
Is MSX1PBHM3/89A pin-compatible with other MicroSMP rectifiers?
Yes, MSX1PBHM3/89A uses the standard MicroSMP (DO-219AD) 2-terminal outline with anode and cathode on opposite ends and cathode marked by a band. It shares identical pad layout and solder profile requirements with all Vishay eSMP® rectifiers in the same package, including MSX1PDHM3/89A and MSX1PGHM3/89A.
Does MSX1PBHM3/89A require additional ESD protection in system design?
No-MSX1PBHM3/89A provides intrinsic ESD protection exceeding 8 kV HBM (JESD22-A114) and 20 kV per ISO 10605. When used as a front-end rectifier in power or I/O lines, it reduces or eliminates the need for discrete TVS diodes in many applications, provided layout follows recommended grounding and trace routing practices.
What does the "HM3" suffix indicate in MSX1PBHM3/89A?
The "HM3" suffix denotes that MSX1PBHM3/89A is halogen-free, RoHS-compliant, and AEC-Q101 qualified. It distinguishes this automotive-grade variant from the commercial "M3" version (e.g., MSX1PB-M3/89A), which shares electrical specs but lacks automotive qualification and enhanced ESD test reporting.
Can MSX1PBHM3/89A be used in 24 V systems?
No-MSX1PBHM3/89A is rated for 100 V VRRM, making it unsuitable for continuous 24 V rail protection where transients may exceed 100 V. For 24 V systems, consider MSX1PDHM3/89A (200 V) or MSX1PGHM3/89A (400 V), which share the same MicroSMP package, AEC-Q101 qualification, and thermal characteristics as MSX1PBHM3/89A.
