Product details
Overview
P6SMB7.5CAHE3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power with 10/1000 μs waveform, 7.5 V standoff voltage (VWM), and 11.3 V maximum clamping voltage (VC) at 53.1 A peak pulse current. It protects signal lines and ICs in automotive sensor units, industrial I/O interfaces, and telecom power rails against ESD and inductive switching transients.
For engineers reviewing the P6SMB7.5CAHE3/52 datasheet, P6SMB7.5CAHE3/52 pinout, P6SMB7.5CAHE3/52 application, or P6SMB7.5CAHE3/52 equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified transient suppressor optimized for bidirectional surge protection in space-constrained PCB layouts requiring stable clamping performance and low leakage (<500 μA at 6.4 V).
Technical Context
The P6SMB7.5CAHE3/52 operates as a symmetrical avalanche diode, conducting equally in both directions above its breakdown threshold of 7.13–7.88 V (tested at 10 mA). Its glass-passivated junction ensures consistent breakdown behavior and low incremental surge resistance under repetitive 0.01% duty cycle pulses.
Designed for surface-mount assembly on 5.0 mm × 5.0 mm copper pads per terminal, it achieves thermal resistance of 100 °C/W (junction-to-ambient) and supports operating junction temperatures from –65 °C to +150 °C. The device meets MSL Level 1 per J-STD-020 with peak reflow temperature up to 260 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 6.4 V - Maximum reverse voltage before significant conduction; defines safe operating margin below clamping onset. |
| VBR (Breakdown Voltage) | 7.13–7.88 V at 10 mA - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 11.3 V at 53.1 A - Peak voltage seen by protected circuit during 10/1000 μs surge; limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000 μs waveform; enables robust system-level surge immunity. |
| ID (Reverse Leakage) | ≤500 μA at 6.4 V - Low off-state current minimizes standby power loss and avoids false triggering in high-impedance circuits. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated pick-and-place and reflow processes. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per AEC specification. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are symmetric; both leads serve as interchangeable surge-current paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Surge Current Input / Output | Acts as either input or output depending on transient polarity; conducts during positive or negative overvoltage events. |
| Cathode (Lead 2) | Surge Current Input / Output | Functionally identical to Anode in bidirectional operation; forms symmetrical clamping path across protected line. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity constraints. |
| 600 W peak pulse rating | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-line) when properly laid out on 5 mm² copper pads. |
| Low clamping ratio (VC/VBR ≈ 1.48) | Minimizes voltage overshoot during fast transients, reducing risk of latch-up or gate oxide damage in protected MOSFETs/ICs. |
| AEC-Q101 qualification | Validates suitability for automotive body electronics, ADAS sensor interfaces, and infotainment power domains. |
| MSL Level 1 moisture sensitivity | Permits unlimited floor life and standard reflow without baking, simplifying manufacturing logistics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5CA | Same VWM (6.4 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; less suitable for industrial 10/1000 μs surge testing | Select when board space is critical and surge threat level is ≤300 W. |
| SMCJ7.5CA | Same VWM (6.4 V), higher PPPM (1500 W), larger SMC package (7.11 mm × 6.22 mm) | Overqualified for 600 W needs; requires more PCB area and higher thermal mass for full rating | Select when future-proofing against higher surge standards or extended thermal derating is required. |
Compared with SMAJ7.5CA and SMCJ7.5CA, the P6SMB7.5CAHE3/52 delivers optimal balance of 600 W surge handling, SMB footprint compatibility, and AEC-Q101 qualification-making it the preferred choice for automotive and industrial designs where reliability, size, and standardized test compliance are jointly prioritized.

FAQ
What is the clamping voltage of the P6SMB7.5CAHE3/52 under a 10/1000 μs surge?
The P6SMB7.5CAHE3/52 has a maximum clamping voltage (VC) of 11.3 V at 53.1 A peak pulse current under the standardized 10/1000 μs waveform. This value is measured per JEDEC standards and reflects the highest voltage imposed on the protected circuit during worst-case transient conditions, ensuring downstream ICs remain within safe operating limits.
Is the P6SMB7.5CAHE3/52 suitable for automotive applications?
Yes, the P6SMB7.5CAHE3/52 is AEC-Q101 qualified and carries the "HE3" suffix denoting RoHS-compliant and automotive-grade construction. It is validated for use in engine control units, body electronics, and ADAS sensor interfaces where sustained operation from –65 °C to +150 °C and resistance to mechanical shock and thermal cycling are mandatory.
How does the bidirectional design of the P6SMB7.5CAHE3/52 affect its placement on the PCB?
The P6SMB7.5CAHE3/52 has no polarity marking and functions identically in both directions, so it can be placed across any two nodes requiring symmetrical overvoltage protection-such as differential signal pairs, AC-coupled lines, or floating power rails-without orientation constraints. This eliminates assembly errors and simplifies layout for balanced protection schemes.
What is the maximum reverse leakage current specified for the P6SMB7.5CAHE3/52?
The P6SMB7.5CAHE3/52 specifies a maximum reverse leakage current (ID) of 500 μA at its stand-off voltage of 6.4 V. This low leakage ensures minimal power drain in battery-operated systems and prevents false triggering in high-impedance monitoring circuits, supporting reliable operation in always-on sensor and IoT edge devices.
Does the P6SMB7.5CAHE3/52 require heatsinking for continuous operation?
No dedicated heatsink is required for the P6SMB7.5CAHE3/52 under normal conditions. Its 5.0 W steady-state power dissipation rating assumes mounting on 5.0 mm × 5.0 mm copper pads per terminal, which provides sufficient thermal conduction. For repetitive surge events, thermal derating per Figure 2 in the datasheet must be applied based on ambient temperature and duty cycle.
