Product details
Overview
P6SMB7.5CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in 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 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P6SMB7.5CAHE3_A/I datasheet, P6SMB7.5CAHE3_A/I pinout, P6SMB7.5CAHE3_A/I application, or P6SMB7.5CAHE3_A/I equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, low clamping ratio (VC/VWM = 1.51), and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This TVS operates as a voltage-clamped shunt protector with symmetrical breakdown in both polarities due to its bidirectional construction. Its glass-passivated junction ensures stable avalanche behavior, while MSL Level 1 rating and matte tin-plated leads support lead-free reflow up to 260 °C peak.
The device delivers 600 W transient suppression under repetitive 0.01% duty cycle conditions and maintains ≤1000 μA reverse leakage at 6.4 V (VWM), enabling reliable protection of low-voltage logic and analog inputs without loading circuits during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 6.4 V - Maximum continuous reverse voltage before clamping begins; sets operating margin for 5 V systems. |
| VBR (Breakdown Voltage) | 7.13–7.88 V at 10 mA - Confirmed symmetric avalanche onset in both directions; enables precise overvoltage thresholding. |
| VC (Clamping Voltage) | 11.3 V at 53.1 A IPPM - Limits transient voltage seen by downstream ICs; clamping ratio = 1.77 relative to VBR max. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - Sustains high-energy surges typical of ISO 7637-2 Load Dump or IEC 61000-4-5 surge events. |
| ID (Reverse Leakage) | ≤500 μA at VWM - Ensures minimal standby current draw in battery-powered sensor nodes. |
| TJ max | 150 °C - Supports operation in under-hood automotive environments and industrial enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5CA | Same VWM (6.4 V) and VC (11.3 V), but 400 W PPPM rating and SMA package (higher RθJA = 140 °C/W) | Limited to lower-duty-cycle or lower-energy transients; less suitable for automotive under-hood thermal environments | Select when cost sensitivity outweighs power handling and thermal performance requirements |
| SMCJ7.5CA | Same VWM and VC, but 1500 W PPPM rating and SMC package (larger footprint, lower RθJA = 50 °C/W) | Overqualified for 600 W needs; occupies 2.5× more PCB area and increases BOM cost | Choose only if future design scaling requires headroom for higher surge standards (e.g., ISO 16750-2) |
Compared with P6SMB7.5CAHE3_A/I, SMAJ7.5CA offers reduced surge robustness and thermal derating margin, while SMCJ7.5CA provides excess power headroom at the expense of board space and cost - making P6SMB7.5CAHE3_A/I the optimal balance for AEC-Q101-compliant 5 V interface protection.

FAQ
What does the "CA" suffix indicate in P6SMB7.5CAHE3_A/I?
The "CA" suffix denotes a bidirectional configuration: the P6SMB7.5CAHE3_A/I provides symmetrical clamping in both polarities, unlike unidirectional variants (e.g., P6SMB7.5A). This eliminates polarity concerns during PCB layout and supports AC-coupled or differential signal lines where voltage reversals occur - critical for protecting CAN, RS-485, or audio interfaces. The device has no cathode marking, confirming its bidirectional nature.
Is P6SMB7.5CAHE3_A/I qualified for automotive applications?
Yes, P6SMB7.5CAHE3_A/I is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay documentation. It undergoes stress testing including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body-model ESD - meeting requirements for under-hood and cabin electronics. The part is rated for TJ = −65 °C to +150 °C and supports reflow profiles up to 260 °C peak, aligning with automotive manufacturing standards.
What is the clamping voltage of P6SMB7.5CAHE3_A/I at its rated peak pulse current?
The P6SMB7.5CAHE3_A/I has a maximum clamping voltage (VC) of 11.3 V at 53.1 A peak pulse current (IPPM), measured using the standard 10/1000 μs double-exponential waveform. This value is guaranteed across temperature and represents the upper limit of voltage imposed on protected circuitry during surge events - essential for ensuring downstream 5 V logic ICs remain within absolute maximum ratings.
How does the SMB package of P6SMB7.5CAHE3_A/I compare to SMA or SMC alternatives?
The SMB (DO-214AA) package of P6SMB7.5CAHE3_A/I offers a balanced trade-off: smaller than SMC (for space-constrained layouts) yet larger than SMA (for better thermal dissipation). With RθJA = 100 °C/W and RθJL = 20 °C/W, it supports higher sustained power handling than SMAJ-series parts while occupying ~40% less area than SMCJ-series devices - making P6SMB7.5CAHE3_A/I ideal for dense automotive ECUs and industrial modules where size and thermal performance must coexist.
Can P6SMB7.5CAHE3_A/I be used in place of a unidirectional TVS like P6SMB7.5A?
No - P6SMB7.5CAHE3_A/I is strictly bidirectional and cannot replace unidirectional parts like P6SMB7.5A in DC-biased applications such as 5 V power rail clamping, where forward conduction must be blocked. Using P6SMB7.5CAHE3_A/I there would allow unintended current flow during normal operation. It is only suitable where symmetrical transient suppression is required, e.g., data lines, AC signals, or floating grounds - always verify circuit topology before substitution.
