Product details
Overview
P6SMB75A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 75 V standoff voltage (VWM), 71.3–78.8 V breakdown voltage (VBR) at 1 mA test current, 103 V maximum clamping voltage at 5.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P6SMB75A-E3/52 datasheet, P6SMB75A-E3/52 pinout, P6SMB75A-E3/52 application, or P6SMB75A-E3/52 equivalent, key selection considerations include its unidirectional polarity, 103 V clamping performance under 5.8 A surge, RoHS-compliant matte tin-plated leads, MSL Level 1 moisture sensitivity, and suitability for automotive-grade designs when ordered with HE3 suffix.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: during transient overvoltage events exceeding its breakdown threshold, it rapidly switches from high-impedance to low-impedance state, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable avalanche characteristics and long-term reliability under repetitive surge stress.
The device is rated for 150 °C maximum junction temperature, exhibits 0.105 %/°C temperature coefficient of VBR, and delivers 5.8 A peak pulse current (IPPM) at 103 V clamping voltage under standardized 10/1000 μs waveform conditions. Thermal resistance is 100 °C/W junction-to-ambient (RθJA) on recommended 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 64.1 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC working limit. |
| VBR (Breakdown Voltage) | 71.3–78.8 V at 1 mA - Voltage at which device enters avalanche conduction; ensures precise triggering margin above VWM. |
| VC (Clamping Voltage) | 103 V at 5.8 A IPPM - Peak voltage seen across protected circuit during worst-case 10/1000 μs surge; determines stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 600 W - Maximum transient energy absorption capability per 10/1000 μs pulse; enables robust protection in industrial environments. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max. | 150 °C - Maximum junction temperature; supports operation in under-hood automotive and industrial control enclosures. |
| RθJA | 100 °C/W - Thermal resistance to ambient on standard PCB pad layout; informs derating requirements above 25 °C ambient. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by band marking on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to system ground or lower-potential rail in unidirectional TVS configuration. |
| Cathode | Current exit terminal during forward conduction; marked with band | Connected to protected line (e.g., I/O, power rail); clamps transients to cathode potential. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables reliable suppression of high-energy transients common in motor drives and power supply inputs without thermal runaway. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ75A | Same SMB package, but lower 400 W PPPM rating and higher 120 V VC at 4.3 A IPPM. | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or GR-1089 Level 3. | Select P6SMB75A-E3/52 when 600 W surge handling and tighter clamping (103 V vs. 120 V) are required. |
| SMCJ75A | Higher-power SMC (DO-214AB) package with 1500 W PPPM and 121 V VC at 12.4 A IPPM. | Physically larger footprint; requires PCB redesign; over-spec'd for space-constrained consumer designs. | Choose P6SMB75A-E3/52 where SMB footprint, cost, and 600 W capability align with board area and surge profile constraints. |
Compared with SMAJ75A and SMCJ75A, the P6SMB75A-E3/52 delivers optimal balance of compact SMB packaging, 600 W surge capacity, and 103 V clamping-making it ideal for space-limited industrial and automotive modules requiring certified transient immunity without over-engineering.

FAQ
What is the clamping voltage of the P6SMB75A-E3/52 under maximum rated surge current?
The P6SMB75A-E3/52 has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM), measured using the standardized 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is critical for ensuring downstream ICs remain within their absolute maximum ratings. The P6SMB75A-E3/52 maintains this clamping performance across its specified operating temperature range.
Is the P6SMB75A-E3/52 suitable for automotive applications?
The P6SMB75A-E3/52 itself is RoHS-compliant commercial-grade (E3 suffix) and not AEC-Q101 qualified; however, Vishay offers the functionally identical P6SMB75AHE3_B variant with AEC-Q101 qualification for automotive use. Engineers selecting the P6SMB75A-E3/52 should verify whether end-equipment requirements mandate automotive qualification-otherwise, the P6SMB75A-E3/52 remains appropriate for non-automotive industrial and consumer applications requiring the same electrical performance.
What is the meaning of the "-E3/52" suffix in P6SMB75A-E3/52?
The "-E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads, while "/52" specifies packaging in 7-inch diameter plastic tape and reel containing 750 units. This ordering code ensures compatibility with standard SMT pick-and-place equipment and confirms adherence to JEDEC moisture sensitivity level 1 (MSL-1), allowing direct placement without baking. The P6SMB75A-E3/52 thus combines environmental compliance, manufacturability, and logistics readiness for high-volume production.
How does the P6SMB75A-E3/52 compare to bidirectional TVS diodes like P6SMB75CA?
The P6SMB75A-E3/52 is unidirectional and intended for DC line protection where polarity is fixed (e.g., VCC-to-GND), offering lower leakage and sharper knee characteristics than bidirectional variants. In contrast, P6SMB75CA provides symmetrical clamping for AC or floating signal lines but exhibits higher reverse leakage and slightly reduced surge handling due to dual-junction architecture. Use the P6SMB75A-E3/52 when protecting polarized rails; select P6SMB75CA only for truly bidirectional paths such as RS-485 or audio lines.
What PCB layout guidance applies to the P6SMB75A-E3/52 for optimal thermal and electrical performance?
For optimal performance, mount the P6SMB75A-E3/52 on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve the specified 100 °C/W junction-to-ambient thermal resistance. Keep traces short and wide between the P6SMB75A-E3/52 and protected node to minimize inductance, and avoid routing noisy signals near its terminals. Ensure the cathode band orientation matches schematic polarity-reversal will prevent proper clamping during positive transients.
