Product details
Overview
P6SMB7.5CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 7.5 V standoff voltage (VWM), 11.3 V maximum clamping voltage at 53.1 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial electronics.
For engineers reviewing the P6SMB7.5CAHE3_A/H datasheet, P6SMB7.5CAHE3_A/H pinout, P6SMB7.5CAHE3_A/H application, or P6SMB7.5CAHE3_A/H equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, low clamping ratio (VC/VWM = 1.51), thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This device operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<500 μA at 6.4 V), while the low incremental surge resistance enables rapid energy absorption during ESD or inductive switching events.
The P6SMB7.5CAHE3_A/H is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 (260 °C peak reflow), supporting high-reliability automotive applications. Its 600 W peak pulse power rating is specified under standardized 10/1000 μs waveform conditions with 0.01% duty cycle, and derating applies above 25 °C ambient per Figure 2.
Key Specifications

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) and VC (11.3 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Less robust for high-energy surges; limited to consumer-grade or low-duty-cycle applications. | Select when board space is constrained and surge threat level is moderate (e.g., internal signal lines). |
| 1.5KE7.5CA | Higher PPPM (1500 W), axial-leaded DO-201 package; larger size, manual assembly only; VWM = 6.4 V, VC = 12.0 V. | Not SMT-compatible; requires through-hole mounting and additional board area; suited for primary-side AC protection. | Choose for legacy designs or high-energy front-end protection where automated placement is not required. |

FAQ
What does the "CA" suffix indicate in P6SMB7.5CAHE3_A/H?
The "CA" suffix denotes a bidirectional configuration - meaning the P6SMB7.5CAHE3_A/H provides symmetrical transient suppression in both voltage polarities, with no cathode marking required. This differs from unidirectional "A" variants (e.g., P6SMB7.5A), which require correct polarity orientation during PCB layout. The CA version is ideal for AC-coupled or differential signal lines where polarity reversal may occur.
Is P6SMB7.5CAHE3_A/H suitable for automotive applications?
Yes - the P6SMB7.5CAHE3_A/H carries the "HE3" suffix, indicating RoHS-compliant construction and full AEC-Q101 qualification. It has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per ANSI/ESDA/JEDEC JS-001, making it approved for use in engine control units, body electronics, and ADAS sensors where reliability under harsh environmental conditions is essential.
What is the maximum clamping voltage of P6SMB7.5CAHE3_A/H and how is it measured?
The maximum clamping voltage (VC) of the P6SMB7.5CAHE3_A/H is 11.3 V, measured at a peak pulse current (IPPM) of 53.1 A using the standardized 10/1000 μs double-exponential waveform. This value represents the highest voltage that will appear across the device during a worst-case transient event, directly determining the overvoltage stress imposed on downstream components such as microcontrollers or transceivers.
How does the SMB package of P6SMB7.5CAHE3_A/H compare to SMA or SMC packages?
The SMB (DO-214AA) package of the P6SMB7.5CAHE3_A/H offers a balanced trade-off: larger than SMA (DO-214AC) for better thermal dissipation (RθJA = 100 °C/W vs. 140 °C/W), yet smaller than SMC (DO-214AB) for denser board layouts. Its 5.59 mm × 4.06 mm footprint supports automated placement and meets IPC-7351B recommendations, unlike axial-leaded alternatives that require manual soldering or through-hole space.
What is the significance of the "_A/H" suffix in P6SMB7.5CAHE3_A/H?
The "_A/H" suffix in P6SMB7.5CAHE3_A/H indicates packaging configuration: "A" refers to the revision code (per Vishay's ordering nomenclature), and "H" specifies 7-inch plastic tape-and-reel delivery with 750 units per reel. This format ensures compatibility with standard SMT pick-and-place equipment and supports high-volume production runs without manual handling or packaging conversion.
