Product details
Overview
P6SMB110CA-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 or power lines. It features a 110 V standoff voltage (VWM), 125 V maximum clamping voltage (VC) at 3.9 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 P6SMB110CA-E3/5B datasheet, P6SMB110CA-E3/5B pinout, P6SMB110CA-E3/5B application, or P6SMB110CA-E3/5B equivalent, key selection criteria include bidirectional surge protection rating, SMB (DO-214AA) package compatibility, RoHS-compliant commercial-grade construction, and AEC-Q101 qualification availability via alternate suffixes.
Technical Context
This bidirectional TVS diode operates symmetrically across both polarities, with breakdown voltage (VBR) specified at 105–116 V (min/max) under 1 mA test current. Its low incremental surge resistance and fast response time enable effective suppression of ESD, lightning-induced surges, and inductive switching transients without affecting normal signal integrity.
Thermal performance is defined by a junction-to-ambient thermal resistance (RθJA) of 100 °C/W and a maximum operating junction temperature of +150 °C. The device is rated for repetitive 0.01% duty cycle pulses and meets J-STD-020 MSL Level 1 moisture sensitivity with 260 °C lead-free reflow compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 94.0 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 105–116 V at 1 mA - Confirmed avalanche onset range; ensures predictable clamping threshold under transient stress. |
| VC (Clamping Voltage) | 152 V at IPPM = 3.9 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capacity for standardized 10/1000 μs waveform; validates robustness against common surges. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Minimal leakage current at rated standoff voltage; preserves low-power circuit integrity and battery life. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial environments. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated pick-and-place and reflow processes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Same SMB package, identical VWM (94 V) and VC (152 V), but rated for 600 W with tighter VBR tolerance (105–115.5 V vs. 105–116 V). | Preferred where tighter parametric consistency is required across production lots; functionally interchangeable in most layouts. | Select SMBJ110CA when statistical process control demands tighter VBR distribution or when qualifying for IPC-A-610 Class 3 assembly. |
| 1.5KE110CA | Through-hole DO-15 package; same 110 V VWM and 152 V VC, but higher 1500 W PPPM rating and larger thermal mass. | Used in legacy or high-energy surge environments (e.g., AC mains input stages); incompatible with SMT-only assembly. | Choose 1.5KE110CA only if board design permits axial/DO-15 placement and requires >600 W single-pulse capability - not a drop-in replacement. |
Compared with SMBJ110CA and 1.5KE110CA, the P6SMB110CA-E3/5B offers optimized cost and footprint for high-volume SMT applications requiring 600 W protection, while maintaining full compatibility with automated manufacturing and commercial-grade reliability requirements.

FAQ
What does the "CA" suffix indicate in P6SMB110CA-E3/5B?
The "CA" suffix denotes a bidirectional configuration - meaning the P6SMB110CA-E3/5B functions identically in both polarities, with symmetrical breakdown and clamping behavior. This eliminates the need for polarity-aware layout and makes it ideal for AC-coupled lines, differential buses, or ungrounded sensor interfaces where voltage transients may swing positive or negative relative to reference.
Is P6SMB110CA-E3/5B suitable for automotive applications?
The P6SMB110CA-E3/5B itself is a commercial-grade part (RoHS-compliant, E3 suffix), not AEC-Q101 qualified. However, Vishay offers the functionally identical P6SMB110CAHE3_B variant - which carries AEC-Q101 qualification and uses the same die and SMB package. For automotive use, specify the HE3_B suffix; the P6SMB110CA-E3/5B remains appropriate for non-automotive industrial or consumer systems.
What is the maximum clamping voltage of P6SMB110CA-E3/5B under surge conditions?
The P6SMB110CA-E3/5B has a maximum clamping voltage (VC) of 152 V at a peak pulse current (IPPM) of 3.9 A, measured using the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across temperature and lot variations per Vishay's datasheet specifications and defines the upper voltage limit imposed on protected circuitry during transient events.
How does the SMB (DO-214AA) package of P6SMB110CA-E3/5B compare to SMA or SMC packages?
The SMB (DO-214AA) package used by P6SMB110CA-E3/5B measures 3.94 mm × 2.20 mm - smaller than SMC (DO-214AB) but larger than SMA (DO-214AC). It provides a balance of surge capability (600 W), thermal dissipation (RθJA = 100 °C/W), and SMT process compatibility. Unlike SMA, SMB supports higher peak pulse power; unlike SMC, it saves board area - making P6SMB110CA-E3/5B optimal for mid-power protection in dense layouts.
Can P6SMB110CA-E3/5B be used in place of a unidirectional TVS like P6SMB110A-E3/5B?
No - the P6SMB110CA-E3/5B is bidirectional and lacks polarity marking, while P6SMB110A-E3/5B is unidirectional with a cathode band. Substituting them requires verifying circuit topology: bidirectional use is mandatory for AC signals or floating references; unidirectional is required for DC rail protection where reverse conduction must be blocked. Using P6SMB110CA-E3/5B in a unidirectional design may allow unintended reverse conduction during normal operation.
