Overview
P6SMB160AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 160 V standoff voltage (VWM), 168 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It clamps transients to 219 V at 2.7 A peak pulse current and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the P6SMB160AHE3_B/H datasheet, P6SMB160AHE3_B/H pinout, P6SMB160AHE3_B/H application, or P6SMB160AHE3_B/H equivalent, this device is selected for robust overvoltage protection in high-reliability DC power rails, sensor interfaces, and automotive control modules where fast response (<1 ns), low clamping ratio, and MSL Level 1 solderability are required.
Technical Context
The P6SMB160AHE3_B/H operates as a unidirectional avalanche diode with cathode-banded polarity, leveraging glass-passivated junction technology for stable breakdown and low incremental surge resistance. Its 10/1000 μs waveform rating reflects standardized surge immunity testing per IEC 61000-4-5.
Designed for transient suppression on DC lines, it delivers 219 V clamping voltage at 2.7 A IPPM, yielding a clamping ratio of 1.37 relative to VWM (160 V), and exhibits ≤1 μA reverse leakage at rated standoff. Thermal resistance is 100 °C/W junction-to-ambient under standard PCB mounting (0.2" × 0.2" copper pads).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 160 V - Maximum continuous reverse operating voltage before conduction begins; defines safe DC rail margin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/52 | Same VWM (160 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 150 °C/W). | Limited to lower-energy surges; unsuitable for ISO 7637-2 Pulse 5a compliance without derating. | Select when board space is constrained and surge threat level is limited to IEC 61000-4-4 only. |
| 1.5SMC160A | Same electrical specs but SMC (DO-214AB) package; 20 % larger footprint, RθJA = 85 °C/W. | Better thermal performance allows higher duty-cycle operation; not AEC-Q101 qualified. | Choose for industrial non-automotive use requiring extended thermal margin at cost of PCB area. |

FAQ
What is the clamping voltage of P6SMB160AHE3_B/H at its rated peak pulse current?
The P6SMB160AHE3_B/H has a maximum clamping voltage (VC) of 219 V at 2.7 A peak pulse current (IPPM), measured under the standardized 10/1000 μs waveform. This value is guaranteed across temperature and ensures protected circuits remain within safe operating limits during surge events. The clamping behavior is consistent due to the device's glass-passivated junction and low incremental surge resistance.
Is P6SMB160AHE3_B/H suitable for automotive applications?
Yes, P6SMB160AHE3_B/H is AEC-Q101 qualified and explicitly designated for automotive use with the "HE3" and "_B" suffixes indicating RoHS-compliant, halogen-free, and automotive-grade construction. It meets requirements for under-hood and cabin modules, including thermal cycling, humidity testing, and surge immunity per ISO 7637-2 and ISO 16750-2. Its 150 °C TJ max supports engine bay deployments.
What does the "_B/H" suffix in P6SMB160AHE3_B/H indicate?
The "_B" denotes AEC-Q101 qualification for the P6SMB160AHE3_B/H series (applicable to 6.8 V–220 V unidirectional/bidirectional variants), while "/H" specifies packaging in 7" diameter plastic tape and reel with 750 units per reel. This ordering code ensures traceable, automotive-grade material delivered in industry-standard surface-mount format compatible with high-speed pick-and-place equipment.
How does P6SMB160AHE3_B/H compare to bidirectional TVS diodes like P6SMB160CA?
P6SMB160AHE3_B/H is unidirectional and intended for DC line protection with defined polarity (cathode-banded), whereas P6SMB160CA is bidirectional and used in AC or floating signal paths. The unidirectional version offers lower leakage (<1 μA vs. ~5 μA for bidirectional at VWM) and slightly tighter VBR tolerance-critical for precision DC rail clamping. P6SMB160AHE3_B/H cannot substitute for P6SMB160CA in AC-coupled applications without circuit redesign.
What PCB layout guidance applies to P6SMB160AHE3_B/H for optimal thermal and electrical performance?
For optimal performance, mount P6SMB160AHE3_B/H using the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. Minimize trace length between the TVS and protected node, avoid vias in high-current paths, and ensure solid ground plane connection to the anode pad. This layout achieves the rated RθJA of 100 °C/W and maintains clamping integrity during repetitive surges.
