Product details
Overview
P6SMB27CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 23.1 V standoff voltage (VWM), 27 V breakdown voltage (VBR min), 37.5 V clamping voltage at 16.0 A peak pulse current, 600 W peak pulse power rating (10/1000 μs), and SMB (DO-214AA) package - deployed in automotive sensor interfaces, industrial I/O modules, and telecom line protection.
For engineers reviewing the P6SMB27CAHE3_A/H datasheet, P6SMB27CAHE3_A/H pinout, P6SMB27CAHE3_A/H application, or P6SMB27CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low clamping ratio (VC/VBR ≈ 1.39), MSL Level 1 moisture sensitivity, and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling suppression of positive and negative transients without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports fast energy diversion during ESD or lightning-induced surges.
The device is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient per Fig. 2; thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). It meets JESD201 Class 2 whisker resistance and is RoHS-compliant with matte tin-plated leads solderable per J-STD-002.
Key Specifications

FAQ
What does the "CA" suffix indicate in P6SMB27CAHE3_A/H?
The "CA" suffix in P6SMB27CAHE3_A/H denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB27A), P6SMB27CAHE3_A/H has no cathode marking and functions identically regardless of terminal orientation - essential for protecting AC-coupled or differential signal lines where polarity is undefined.
Is P6SMB27CAHE3_A/H qualified for automotive use?
Yes, P6SMB27CAHE3_A/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay documentation. This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD - validating its suitability for under-hood and cabin applications such as body control modules, ADAS camera interfaces, and infotainment power rails.
What is the maximum clamping voltage of P6SMB27CAHE3_A/H and why does it matter?
The maximum clamping voltage of P6SMB27CAHE3_A/H is 37.5 V at 16.0 A (10/1000 μs waveform). This value represents the highest voltage imposed on the protected circuit during a surge event - directly determining whether downstream ICs (e.g., 3.3 V or 5 V logic, CAN transceivers) remain within absolute maximum ratings. A lower VC improves system robustness, especially in low-voltage domains.
How does the SMB (DO-214AA) package of P6SMB27CAHE3_A/H affect PCB layout?
The SMB (DO-214AA) package of P6SMB27CAHE3_A/H requires a standardized 0.205" × 0.220" pad layout with 0.2" × 0.2" copper areas per terminal to achieve rated 600 W pulse power. Its compact size supports high-density routing, but thermal relief must be minimized to maintain low RθJA; designers must avoid excessive trace length between P6SMB27CAHE3_A/H and protected ICs to preserve sub-nanosecond response.
What is the significance of the "_A/H" suffix in P6SMB27CAHE3_A/H?
The "_A/H" suffix in P6SMB27CAHE3_A/H indicates packaging format: "H" specifies 7" diameter plastic tape and reel with 750 units per reel, while "A" denotes the revision code per Vishay's internal documentation. This ordering code ensures traceability to the 09-Jan-2024 revision (Document Number: 88370) and guarantees compliance with RoHS, JESD201 Class 2 whisker resistance, and AEC-Q101 test records.
