Product details
Overview
P6SMB7.5CA-E3/52 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 rating with 10/1000 μs waveform - deployed in automotive sensor interfaces, industrial I/O protection, and telecom line conditioning.
For engineers reviewing the P6SMB7.5CA-E3/52 datasheet, P6SMB7.5CA-E3/52 pinout, P6SMB7.5CA-E3/52 application, or P6SMB7.5CA-E3/52 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM = 1.51), AEC-Q101 qualification eligibility, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<500 μA at 6.4 V), while the low incremental surge resistance enables rapid energy absorption during ESD or lightning-induced surges.
The device is rated for repetitive 10/1000 μs transients at 0.01% duty cycle and supports operating junction temperatures from –65 °C to +150 °C. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), requiring minimal PCB copper area for thermal management in space-constrained designs.
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 |
|---|---|---|---|
| SMBJ7.5CA | Same SMB package, identical VWM (6.4 V) and VC (11.3 V), but rated for 600 W with tighter VBR tolerance (±3.5% vs. ±5%). | Preferred where tighter voltage matching is required across production lots, e.g., precision analog front-ends. | Select SMBJ7.5CA if statistical process control demands lower parametric variation; otherwise P6SMB7.5CA-E3/52 offers cost-effective volume scalability. |
| 1.5SMC7.5CA | Larger SMC (DO-214AB) package, same electrical specs but higher thermal mass (RθJA = 65 °C/W); 1.5 kW peak power rating. | Suitable for high-reliability industrial systems requiring extended surge endurance or elevated ambient temperature operation (>105 °C). | Choose 1.5SMC7.5CA only when board space allows larger footprint and thermal budget exceeds 100 °C/W - not a drop-in replacement. |
Compared with SMBJ7.5CA, P6SMB7.5CA-E3/52 trades minor VBR tolerance for broader qualification coverage and lower unit cost; versus 1.5SMC7.5CA, it delivers identical clamping performance in 30% smaller area but requires careful thermal pad design to maintain 150 °C junction limit.

FAQ
What is the clamping voltage of P6SMB7.5CA-E3/52 at its rated peak pulse current?
The P6SMB7.5CA-E3/52 has a maximum clamping voltage (VC) of 11.3 V at 53.1 A peak pulse current (IPPM), measured under the standard 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range and represents the highest voltage the protected circuit will experience during a defined surge event. The low VC/VWM ratio of 1.77 ensures effective protection for 5 V and 3.3 V logic interfaces without overstressing downstream components.
Is P6SMB7.5CA-E3/52 suitable for automotive applications?
P6SMB7.5CA-E3/52 itself is commercial-grade (RoHS-compliant, MSL Level 1), but the P6SMB7.5CAHE3_B variant is AEC-Q101 qualified for automotive use. Engineers selecting P6SMB7.5CA-E3/52 for automotive prototypes must verify qualification status via Vishay's ordering code matrix - the "HE3_B" suffix denotes automotive qualification, while "E3/52" indicates commercial tape-and-reel packaging. No requalification is needed if migrating from E3 to HE3_B in same layout.
How does the bidirectional nature of P6SMB7.5CA-E3/52 affect PCB layout?
The bidirectional design of P6SMB7.5CA-E3/52 eliminates polarity marking and orientation constraints - the device has no cathode band and can be placed in either direction across a differential pair or AC signal line. This simplifies pick-and-place programming and reduces assembly errors. Layout best practice remains mounting on 0.2" × 0.2" copper pads per terminal to achieve specified thermal and surge ratings, as verified in Vishay's datasheet Figure 2.
What is the maximum operating temperature for P6SMB7.5CA-E3/52?
P6SMB7.5CA-E3/52 has a maximum junction temperature (TJ max.) of +150 °C and operates from –65 °C to +150 °C. At ambient temperatures above 25 °C, power derating applies per Figure 2 in the datasheet: for example, at TA = 85 °C, the maximum allowable peak pulse power drops to ~420 W. PCB thermal design - including copper pad size and proximity to heat sources - directly impacts achievable TJ and must be validated for each end application.
Does P6SMB7.5CA-E3/52 meet industry surge immunity standards?
Yes, P6SMB7.5CA-E3/52 supports compliance with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) when applied per Vishay's recommended layout and coordinated with system-level protection elements. Its 600 W peak pulse rating aligns with Level 3 (1 kV/2 Ω) of IEC 61000-4-5, and its fast response time (<1 ns) ensures clamping occurs before vulnerable IC structures are stressed. Full system validation remains the designer's responsibility.
