Product details
Overview
MSP5.0AHM3/89A from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in MicroSMP (DO-219AD) package, rated for 5.0 V stand-off voltage, 7.07 V max breakdown at 10 mA, 150 W peak pulse power (10/1000 μs), and AEC-Q101 qualified for automotive applications including sensor line and MOSFET gate protection.
For engineers reviewing the MSP5.0AHM3/89A datasheet, MSP5.0AHM3/89A pinout, MSP5.0AHM3/89A application, or MSP5.0AHM3/89A equivalent, key selection criteria include clamping voltage at 16.3 A (9.2 V), junction temperature range (−55 °C to +150 °C), ESD robustness (15 kV air / 8 kV contact), and automotive-grade whisker-tested matte tin terminations.
Technical Context
The MSP5.0AHM3/89A employs an oxide planar chip junction and operates exclusively in unidirectional polarity, with cathode denoted by a color band. Its thermal design relies on 6.0 mm × 6.0 mm copper pads per terminal to achieve RθJM = 30 °C/W and sustain 150 W surge dissipation.
It meets J-STD-020C MSL Level 1, supports reflow up to 260 °C peak, and delivers 9.2 V maximum clamping voltage at 16.3 A IPPM (10/1000 μs), calculated via VCL = RD × IPPM + VBR(max) where RD = 0.131 Ω.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum reverse stand-off voltage before significant leakage; ensures no conduction during normal 5 V rail operation. |
| VBR (min/max) | 6.40 V / 7.07 V at 10 mA - Tight breakdown tolerance enables precise overvoltage triggering in 5 V systems. |
| PPPM | 150 W (10/1000 μs) - Sustains high-energy transients common in automotive load-dump and inductive switching events. |
| VCL @ IPPM | 9.2 V at 16.3 A - Clamping level protects downstream 5 V ICs with margin below typical 12 V absolute maximum ratings. |
| TJ Range | −55 °C to +150 °C - Supports under-hood automotive environments and industrial control enclosures without derating. |
| ESD Rating | 15 kV (air), 8 kV (contact) - Exceeds IEC 61000-4-2 Level 4 for system-level ESD immunity in sensor interfaces. |
| Package | MicroSMP (DO-219AD), 0.091" × 0.055" × 0.022" - Ultra-low profile (0.65 mm height) enables placement on dense PCBs and automated assembly. |
Pinout & Package
MicroSMP (DO-219AD) package with two terminals: anode and cathode. Cathode identified by molded color band. Matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; connected to protected line (e.g., signal or power rail) | Acts as reference node for clamping; must be routed with low-inductance path to ground via TVS cathode. |
| Cathode | Current exit point during transient suppression; tied to system ground or low-impedance return path | Color band marks cathode; requires direct, short trace to ground plane to minimize clamping overshoot and inductance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including engine control units, ADAS sensors, and body electronics requiring zero field failure risk. |
| 0.65 mm profile height | Enables placement on space-constrained boards such as camera modules and compact ECUs without interfering with adjacent components. |
| Halogen-free, RoHS-compliant HM3 suffix | Meets automotive material compliance requirements (JESD201 Class 2 whisker test, UL 94 V-0 molding compound). |
| 150 W peak pulse power | Handles ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 5a (load dump) waveforms in 12 V vehicle systems. |
Applications
| Automotive Sensor Protection | Industrial I/O Line Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0AHE3/5BT | Same 5.0 V VWM, but SMA (DO-214AC) package (2.5 mm height); 400 W PPPM; higher clamping (11.2 V @ 32.4 A) | Higher surge capacity suits industrial power supplies; taller profile limits use in ultra-thin automotive modules. | Select when higher energy handling is required and board height allows SMA footprint. |
| TPSMA6L5.0A-Q1 | AEC-Q101 qualified; same MicroSMP package; lower VBR (6.12–6.78 V); tighter VCL (9.0 V @ 16.7 A); 100 W PPPM | Better clamping precision for low-voltage logic rails; reduced surge rating limits use in high-energy load-dump scenarios. | Select when tighter clamping tolerance and lower VCL are prioritized over peak power handling. |
Compared with SMAJ5.0AHE3/5BT and TPSMA6L5.0A-Q1, the MSP5.0AHM3/89A uniquely balances AEC-Q101 compliance, MicroSMP low-profile packaging, 150 W surge capability, and 9.2 V clamping-making it optimal for space-constrained automotive electronics where both reliability and board real estate are critical.

FAQ
What is the maximum clamping voltage of the MSP5.0AHM3/89A at its rated peak pulse current?
The MSP5.0AHM3/89A has a maximum clamping voltage (VCL) of 9.2 V at 16.3 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per standard test methods and reflects actual device behavior when suppressing transients on 5 V lines. The MSP5.0AHM3/89A maintains this clamping performance across its full operating temperature range of −55 °C to +150 °C.
Is the MSP5.0AHM3/89A suitable for automotive applications?
Yes, the MSP5.0AHM3/89A is AEC-Q101 qualified and built with HM3 suffix-indicating automotive-grade construction, including JESD 201 Class 2 whisker resistance and halogen-free, RoHS-compliant materials. It is explicitly designed for automotive sensor protection, ECU power rails, and communication line safeguarding. The MSP5.0AHM3/89A meets stringent automotive reliability and thermal cycling requirements.
What does the "HM3" suffix indicate in MSP5.0AHM3/89A?
The "HM3" suffix in MSP5.0AHM3/89A denotes halogen-free, RoHS-compliant, and automotive-grade construction-including JESD 201 Class 2 whisker resistance, UL 94 V-0 molding compound, and qualification per AEC-Q101. It distinguishes the part from industrial-grade "M3" variants and confirms suitability for under-hood and safety-critical vehicle systems. The MSP5.0AHM3/89A carries this suffix to assure full automotive material and process compliance.
What is the thermal resistance from junction to mount (RθJM) for the MSP5.0AHM3/89A?
The MSP5.0AHM3/89A has a typical junction-to-mount thermal resistance (RθJM) of 30 °C/W when mounted on 6.0 mm × 6.0 mm copper pads per terminal. This low thermal resistance enables effective heat transfer during 150 W transient events and supports reliable operation at junction temperatures up to +150 °C. The MSP5.0AHM3/89A achieves this performance using its MicroSMP package's optimized thermal pad layout and matte tin terminations.
How does the MSP5.0AHM3/89A compare to the MSP3V3HM3/89A in terms of electrical parameters?
The MSP5.0AHM3/89A is rated for 5.0 V stand-off voltage (VWM) and 6.40–7.07 V breakdown (VBR), whereas the MSP3V3HM3/89A targets 3.3 V systems with 4.10–5.10 V VBR. Both share identical MicroSMP packaging, AEC-Q101 qualification, and 150 W PPPM, but differ in clamping (9.2 V vs. 7.6 V) and leakage (<100 μA vs. <200 μA at VWM). The MSP5.0AHM3/89A is selected for 5 V rail protection; MSP3V3HM3/89A for 3.3 V logic and USB interfaces.
