Product details
Overview
MSMP8.0AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in MicroSMP (DO-219AD) package, with 8.0 V stand-off voltage (VWM), 8.89–9.83 V breakdown voltage (VBR), 150 W peak pulse power (10/1000 μs), and AEC-Q101 qualification. It protects automotive sensor signal lines and MOSFET gates against ESD and inductive switching transients.
For engineers reviewing the MSMP8.0AHM3/H datasheet, MSMP8.0AHM3/H pinout, MSMP8.0AHM3/H application, or MSMP8.0AHM3/H equivalent, key selection criteria include clamping voltage (13.6 V max at IPPM), low-profile height (0.65 mm), MSL Level 1 rating, and verified 15 kV air / 8 kV contact ESD immunity per IEC 61000-4-2 and AEC-Q101-001.
Technical Context
This device operates as a unidirectional TVS diode with oxide planar chip junction, designed for fast response to transient overvoltages. Its clamping behavior follows VCL = RD × IPP + VBR(max), with RD = 0.342 Ω and VBR(max) = 9.83 V - enabling predictable suppression under 10/1000 μs surges up to 11.0 A.
Thermal performance is defined by RθJM = 30 °C/W (junction-to-mount) and RθJA = 250 °C/W (junction-to-ambient), requiring minimum 6.0 mm × 6.0 mm copper pads per terminal for rated 150 W pulse handling. It meets J-STD-020C MSL Level 1 and LF peak of 260 °C for reflow compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - maximum reverse stand-off voltage before conduction; ensures no leakage during normal 8 V rail operation. |
| VBR (min/max) | 8.89 V / 9.83 V at 1.0 mA - precise breakdown threshold defining turn-on onset for transient clamping. |
| VC (max) @ IPPM | 13.6 V at 11.0 A (10/1000 μs) - peak clamped voltage protecting downstream ICs within safe voltage margins. |
| PPPM | 150 W (10/1000 μs) - surge energy absorption capability validated on 6.0 mm × 6.0 mm PCB copper pads. |
| ESD Rating | 15 kV air / 8 kV contact - exceeds IEC 61000-4-2 Level 4, suitable for automotive sensor interface protection. |
| Package | MicroSMP (DO-219AD) - 2.30 mm × 1.10 mm footprint, 0.65 mm height, halogen-free, RoHS-compliant, AEC-Q101 qualified. |
| TJ max | 150 °C - maximum operating junction temperature enabling use in under-hood automotive environments. |
Pinout & Package
MicroSMP (DO-219AD) is a 2-terminal surface-mount package with cathode denoted by a color band. Anode and cathode terminals are located on opposite ends of the rectangular die; polarity must be observed during PCB layout to ensure correct transient shunting path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (for unidirectional operation) | Connected to protected line (e.g., sensor output); conducts only when line voltage exceeds VBR relative to cathode. |
| Cathode | Transient current return path to ground or reference rail | Marked by color band; must connect to low-impedance ground plane to achieve specified clamping performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, ADAS sensors, and body electronics per stress test requirements. |
| Low profile (0.65 mm height) | Enables placement in space-constrained modules such as camera ECUs and radar front-ends without mechanical interference. |
| Oxide planar chip junction | Ensures stable, repeatable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| Matte tin-plated leads | Guarantees solderability per J-STD-002 and JESD 22-B102, with whisker resistance per JESD 201 Class 2. |
| UL 94 V-0 molding compound | Provides flame-retardant encapsulation required for automotive and industrial safety compliance. |
Applications
| Automotive Sensor Protection | Industrial Motor Drive I/O |
|---|---|
Use Scenario: Protecting LIN/CAN sensor signal lines (e.g., temperature, pressure, position) from load dump and ESD events in vehicle cabins and powertrains. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between sensor output and microcontroller input to limit voltage excursions below absolute maximum ratings. Use Value: Maintains signal integrity during 15 kV ESD strikes and 10/1000 μs inductive spikes while adding < 0.3 pF capacitance to preserve rise time. |
Use Scenario: Safeguarding digital I/O pins of PLC modules and motor driver gate drivers exposed to relay coil flyback and field wiring transients. IC Role / Device Role / Timing Role: Standoff-rated transient suppressor mounted directly at connector entry points to divert surge energy before reaching logic-level circuitry. Use Value: Clamps to ≤13.6 V at 11 A, preventing latch-up or permanent damage to 3.3 V/5 V interface ICs in harsh factory environments. |
| Automotive Power Supply Rail | Consumer IoT Interface Protection |
Use Scenario: Secondary protection on 12 V battery-fed subsystem rails (e.g., infotainment USB-C port, lighting control) where primary TVS or fuse coordination is required. IC Role / Device Role / Timing Role: Fast-reacting secondary clamp working in concert with upstream fuses or polymer PTCs to limit let-through energy during sustained overvoltage. Use Value: Withstands repeated 150 W pulses and maintains VWM stability across -55 °C to +150 °C, supporting ASIL-B system robustness. |
Use Scenario: ESD hardening of USB, I²C, and UART lines in smart home hubs and wearable chargers subjected to user-handling discharge. IC Role / Device Role / Timing Role: Board-level ESD suppressor placed adjacent to connectors to absorb human-body-model discharges before reaching SoC GPIOs. Use Value: Delivers 8 kV contact / 15 kV air ESD immunity in a 2.3 mm × 1.1 mm footprint - minimizing PCB area vs. larger SOD-323 alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A-HF | Same VWM/VBR range but SMA (DO-214AC) package (4.5 mm × 2.7 mm); higher RθJA (400 °C/W); non-AEC-Q101. | Limited to commercial-grade industrial or consumer use; not qualified for automotive under-hood deployment. | Select when cost sensitivity outweighs space constraints and AEC-Q101 is not mandated. |
| SMCJ8.0A-QH | Higher PPPM (1500 W), DO-214AB package (7.1 mm × 6.2 mm); AEC-Q101 qualified; VBR = 8.89–9.83 V same as MSMP8.0AHM3/H. | Used where higher surge margin is needed (e.g., alternator-connected systems), but requires 3× board area. | Choose when system-level surge testing exceeds 150 W and board space permits larger footprint. |
Compared with SMAJ8.0A-HF and SMCJ8.0A-QH, MSMP8.0AHM3/H uniquely delivers AEC-Q101 qualification in the smallest qualified footprint (MicroSMP), enabling high-density automotive PCB layouts without sacrificing surge rating or thermal derating compliance.
