Product details
Overview
MSP5.0A-E3/89A 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, 6.40–7.07 V breakdown at 10 mA, 150 W peak pulse power (10/1000 μs), and AEC-Q101 qualified for automotive-grade surge protection on signal and power lines.
For engineers reviewing the MSP5.0A-E3/89A datasheet, MSP5.0A-E3/89A pinout, MSP5.0A-E3/89A application, or MSP5.0A-E3/89A equivalent, key selection criteria include clamping voltage (9.2 V max at 16.3 A), low profile (0.65 mm height), ESD robustness (15 kV air / 8 kV contact), thermal resistance (RθJA = 250 °C/W), and MicroSMP mechanical compatibility with automated SMT placement.
Technical Context
The MSP5.0A-E3/89A employs an oxide planar chip junction and operates as a unidirectional TVS diode, conducting only during positive transients relative to cathode. Its clamping behavior follows VCL = RD × IPPM + VBR(max), with dynamic resistance RD = 0.131 Ω (10/1000 μs) enabling predictable overvoltage suppression under fast-rising surges.
Designed for PCB top-side mounting only, it meets MSL Level 1 per J-STD-020C with 260 °C peak reflow, supports 1 oz. copper pad layouts (6.0 mm × 6.0 mm per terminal), and delivers 150 °C maximum junction temperature operation with derated power dissipation above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum reverse stand-off voltage before conduction; ensures no leakage during normal 5 V system operation. |
| VBR (min/max) | 6.40 V / 7.07 V at 10 mA - Confirmed breakdown range defines turn-on threshold tolerance for transient detection. |
| VCL @ IPPM | 9.2 V max at 16.3 A (10/1000 μs) - Clamping voltage limits downstream IC stress during standardized surge events. |
| PPPM | 150 W - Peak pulse power handling capacity for 10/1000 μs waveform; determines survivability against inductive switching spikes. |
| RD | 0.131 Ω - Dynamic resistance directly impacts clamping voltage rise under surge current; enables precise VCL calculation. |
| TJ max | 150 °C - Maximum junction temperature sets thermal design margin for continuous power cycling and high-ambient environments. |
| ESD Rating | 15 kV air / 8 kV contact per IEC 61000-4-2 - Validates immunity to human-body model discharges in end-equipment handling and operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Same VWM (5.0 V), higher VCL (10.8 V @ 14.8 A), SMA package (larger footprint, 2.3 mm height) | Less suitable for ultra-thin designs; better thermal mass for higher average power but incompatible with MicroSMP land patterns | Select SMAJ5.0A only if board space allows larger package and higher clamping voltage is acceptable. |
| SMF5.0A | Same VWM (5.0 V), lower PPPM (200 W), SOD-123FL package (1.7 mm height, 2.7 mm × 1.7 mm) | Higher clamping (11.2 V @ 17.9 A) and reduced surge margin; not AEC-Q101 qualified | Choose SMF5.0A for cost-sensitive non-automotive applications where 200 W rating suffices and AEC-Q101 is unnecessary. |
Compared with SMAJ5.0A and SMF5.0A, the MSP5.0A-E3/89A provides the lowest profile (0.65 mm), tightest clamping (9.2 V), and automotive qualification-making it optimal for space-constrained, safety-critical 5 V line protection where layout density and reliability are prioritized over raw power rating.

FAQ
What is the exact package type and dimensions of the MSP5.0A-E3/89A?
The MSP5.0A-E3/89A uses the MicroSMP (DO-219AD) package, measuring 2.70 mm × 1.40 mm × 0.65 mm (L × W × H) with a cathode band marking. Its footprint requires 6.0 mm × 6.0 mm copper pads per terminal for full 150 W pulse rating, and it complies with MSL Level 1 per J-STD-020C for lead-free reflow up to 260 °C. This package is distinct from SMA or SOD-123 variants.
Does the MSP5.0A-E3/89A support bidirectional transient suppression?
No, the MSP5.0A-E3/89A is strictly unidirectional, as confirmed by its polarity specification and cathode-band marking. It clamps only when the anode voltage exceeds the cathode by ≥6.40 V. For bidirectional protection, Vishay offers separate part numbers such as the SMBJ5.0CA; the MSP5.0A-E3/89A must be oriented correctly in-circuit to avoid reverse-bias failure.
What is the maximum clamping voltage of the MSP5.0A-E3/89A under standard test conditions?
The MSP5.0A-E3/89A has a maximum clamping voltage of 9.2 V at 16.3 A using the 10/1000 μs waveform, as specified in the Electrical Characteristics table. This value is derived from VCL = RD × IPPM + VBR(max), where RD = 0.131 Ω and VBR(max) = 7.07 V. It does not exceed 9.2 V under validated test conditions.
Is the MSP5.0A-E3/89A qualified for automotive applications?
Yes, the MSP5.0A-E3/89A is AEC-Q101 qualified, as explicitly stated in the Features section and Immunity table. It meets Human Body Model Class H3B (>8 kV contact) and supports operating junction temperatures from –55 °C to +150 °C-fulfilling requirements for under-hood and cabin-mounted automotive electronics including sensor interfaces and body control modules.
How does the MSP5.0A-E3/89A compare to the MSP3V3 variant in terms of electrical parameters?
The MSP5.0A-E3/89A differs from MSP3V3 in stand-off voltage (5.0 V vs. 3.3 V), breakdown range (6.40–7.07 V vs. 4.10–5.10 V), and clamping voltage (9.2 V vs. 7.6 V at respective IPPM). Both share identical MicroSMP packaging, 150 W rating, and AEC-Q101 qualification-but MSP5.0A-E3/89A is intended for 5 V systems, while MSP3V3 targets 3.3 V logic and interface protection.
