Product details
Overview
P6SMB7.5A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features 600 W peak pulse power (10/1000 μs), 7.13–7.88 V breakdown voltage at 10 mA, 6.40 V stand-off voltage, 11.3 V maximum clamping voltage at 53.1 A peak pulse current, and operates from –65 °C to +150 °C junction temperature.
For engineers reviewing the P6SMB7.5A-E3/52 datasheet, P6SMB7.5A-E3/52 pinout, P6SMB7.5A-E3/52 application, or P6SMB7.5A-E3/52 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, IPPM capability under system-level surge stress (e.g., ISO 7637-2 Pulse 1/2a), thermal derating above 25 °C ambient, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and lightning-induced surges (IEC 61000-4-5). Its unidirectional polarity-marked with cathode band-provides forward conduction path only during reverse overvoltage events.
The device is rated for 600 W peak pulse power with 0.01% duty cycle, derated linearly above 25 °C per Fig. 2, and exhibits 0.061 %/°C temperature coefficient of VBR. Thermal resistance is 100 °C/W junction-to-ambient (on recommended pad layout) and 20 °C/W junction-to-lead.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Same SMB package, but 400 W peak pulse power (vs. 600 W); VC = 12.0 V at 32.9 A | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); insufficient for ISO 7637-2 Pulse 5a | Select P6SMB7.5A-E3/52 when 600 W surge handling and tighter clamping (11.3 V) are required for automotive or industrial use. |
| 1.5SMC7.5A | Higher-power SMC package (1500 W), larger footprint (0.285" × 0.235"), VC = 12.9 V at 116 A | Requires PCB area increase and layout revision; better suited for primary-level AC/DC input protection | Choose P6SMB7.5A-E3/52 for space-constrained 5 V rail protection where SMB footprint and 11.3 V clamping are critical. |
Compared with SMAJ7.5A and 1.5SMC7.5A, P6SMB7.5A-E3/52 delivers optimal balance of 600 W surge capacity, 11.3 V clamping, and SMB footprint-making it preferred for secondary-side 5 V/24 V DC protection where board space and voltage margin are constrained.

FAQ
What is the maximum clamping voltage of P6SMB7.5A-E3/52 under surge conditions?
The P6SMB7.5A-E3/52 has a maximum clamping voltage (VC) of 11.3 V at 53.1 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per JEDEC standards and represents the highest voltage the protected circuit will experience during a worst-case transient event. The P6SMB7.5A-E3/52 maintains this clamping performance across its full operating temperature range when mounted on the recommended 0.2" × 0.2" copper pads.
Is P6SMB7.5A-E3/52 suitable for automotive applications requiring AEC-Q101 qualification?
No, P6SMB7.5A-E3/52 is not AEC-Q101 qualified. It carries the "E3" suffix indicating RoHS-compliant commercial grade. For automotive use, Vishay offers the P6SMB7.5AHE3_B variant (with "HE3" and "B" suffixes), which is explicitly AEC-Q101 qualified and tested per stress test conditions including temperature cycling, HTRB, and ESD. The P6SMB7.5A-E3/52 should be used only in non-automotive or non-safety-critical industrial/consumer applications.
What is the thermal resistance of P6SMB7.5A-E3/52 and how does it affect power derating?
The P6SMB7.5A-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended 0.2" × 0.2" copper pads. This value increases significantly with smaller pads or no copper pour. As ambient temperature rises above 25 °C, the device's peak pulse power must be linearly derated per Figure 2 in the datasheet-e.g., at 85 °C ambient, usable PPPM drops to ~60% of 600 W. The P6SMB7.5A-E3/52's RθJL of 20 °C/W supports efficient heat transfer to PCB traces.
How does the unidirectional configuration of P6SMB7.5A-E3/52 impact its placement on a PCB?
The unidirectional configuration of P6SMB7.5A-E3/52 requires correct orientation: the cathode (marked by a band) must connect to the protected line (e.g., 5 V rail), and the anode to ground. This allows forward conduction only during negative transients on the anode side, while blocking normal forward bias. Incorrect orientation renders the device ineffective against positive surges. The P6SMB7.5A-E3/52 cannot replace bidirectional types (e.g., P6SMB7.5CA) without circuit redesign.
What are the soldering requirements for P6SMB7.5A-E3/52 during reflow assembly?
P6SMB7.5A-E3/52 meets J-STD-020 MSL Level 1, permitting unlimited floor life and standard lead-free reflow profiles with a maximum peak temperature of 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for solderability. No pre-baking is required. The P6SMB7.5A-E3/52 must be mounted on the specified 0.2" × 0.2" copper pads per datasheet mechanical drawing to ensure thermal and electrical performance integrity.
