Product details
Overview
P6SMB160CA-E3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal and power lines. It features a 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB160CA-E3/5B datasheet, P6SMB160CA-E3/5B pinout, P6SMB160CA-E3/5B application, or P6SMB160CA-E3/5B equivalent, key selection criteria include bidirectional clamping behavior, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status (via HE3/HM3 variants), thermal resistance (RθJA = 100 °C/W), and compliance with IEC 61000-4-2/4-4/4-5 surge immunity standards.
Technical Context
This bidirectional TVS diode operates symmetrically across both polarities, delivering consistent clamping performance without polarity dependence. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance enables rapid energy diversion during transient events.
The device is rated for repetitive 10/1000 μs surges at 0.01% duty cycle and supports operation from −65 °C to +150 °C junction temperature. Mounted on 5.0 mm × 5.0 mm copper pads, it achieves specified PPPM and IPPM ratings per JEDEC test conditions, with thermal derating above 25 °C ambient per Figure 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 136 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown) | 152–168 V at 1.0 mA - Voltage range where device enters avalanche conduction; ensures reliable turn-on during transients. |
| VC (Clamping) | 219 V at IPPM = 2.7 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM | 600 W - Peak transient power dissipation capability; validates robustness against IEC 61000-4-5 Level 4 surges. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance; informs PCB copper pad sizing and layout for thermal reliability. |
| Package | SMB (DO-214AA) - Surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated placement and reflow. |
| AEC-Q101 | Qualified variant available (HE3/HM3 suffixes) - Confirmed reliability for automotive ECUs, ADAS sensors, and infotainment systems. |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns. |
| 600 W peak pulse power | Supports IEC 61000-4-5 surge immunity up to 4 kV (line-earth) and 2 kV (line-line) in standard configurations. |
| Glass-passivated junction | Ensures long-term stability of VBR and low leakage drift over temperature and lifetime. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity handling. |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on protected ICs compared to higher-ratio suppressors. |

FAQ
What is the clamping voltage of P6SMB160CA-E3/5B at its rated peak pulse current?
The P6SMB160CA-E3/5B has a maximum clamping voltage (VC) of 219 V at a peak pulse current (IPPM) of 2.7 A using the standard 10/1000 μs waveform. This value is measured under JEDEC-defined test conditions with the device mounted on 5.0 mm × 5.0 mm copper pads, and represents the upper voltage limit imposed on protected circuitry during surge events.
Is P6SMB160CA-E3/5B suitable for automotive applications?
P6SMB160CA-E3/5B itself is RoHS-compliant and commercial-grade; however, the P6SMB160CA-HE3/5B variant is AEC-Q101 qualified for automotive use. Engineers selecting P6SMB160CA-E3/5B for automotive designs must verify qualification status via the HE3 suffix and confirm compliance with vehicle manufacturer requirements before deployment in ECUs or ADAS modules.
How does the bidirectional configuration of P6SMB160CA-E3/5B affect its circuit implementation?
The CA suffix denotes bidirectional construction, meaning P6SMB160CA-E3/5B conducts identically in both polarities and requires no orientation during placement. It functions as a symmetric voltage clamp across differential lines or ungrounded signals - eliminating the need for polarity-aware routing and simplifying layout for AC-coupled interfaces like RS-485 or Ethernet PHYs.
What is the thermal resistance of P6SMB160CA-E3/5B, and how does it impact PCB layout?
P6SMB160CA-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures during repetitive surges, designers must allocate sufficient copper area and avoid excessive trace length or thermal bottlenecks between the SMB package leads and thermal planes.
Does P6SMB160CA-E3/5B meet industry-standard surge immunity requirements?
Yes - P6SMB160CA-E3/5B delivers 600 W peak pulse power with a 10/1000 μs waveform, enabling compliance with IEC 61000-4-5 Level 4 (4 kV line-earth, 2 kV line-line) when properly applied in conjunction with appropriate series impedance. Its 219 V clamping voltage ensures protected ICs remain within safe operating limits during standardized surge testing.
