Product details
Overview
P4SMA110CA-E3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P4SMA 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 2.0 A peak pulse current, and 400 W peak pulse power capability with a 10/1000 µs waveform - suitable for protecting MOSFETs, sensor interfaces, and telecom line drivers against inductive switching surges.
For engineers reviewing the P4SMA110CA-E3/61 datasheet, P4SMA110CA-E3/61 pinout, P4SMA110CA-E3/61 application, or P4SMA110CA-E3/61 equivalent, this device delivers verified bidirectional surge suppression in SMA (DO-214AC) package with AEC-Q101 qualification option, low incremental surge resistance, and MSL Level 1 moisture sensitivity rating for high-reliability automated assembly.
Technical Context
The P4SMA110CA-E3/61 operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its breakdown voltage (VBR) is specified at 105–116 V (min/max) under 1 mA test current, with a temperature coefficient of 0.107 %/°C - enabling predictable voltage drift across operating junction temperatures from –65 °C to +150 °C.
It sustains 400 W peak pulse power per 10/1000 µs waveform when mounted on 5.0 mm × 5.0 mm copper pads, derating linearly above 25 °C ambient (RθJA = 120 °C/W). The device exhibits fast response time (<1 ns), low clamping ratio (VC/VBR ≈ 1.14), and meets UL 497B recognition for protector classification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 94.0 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 105–116 V at IT = 1 mA - Avalanche onset range; ensures consistent turn-on behavior across production lots. |
| VC (Clamping Voltage) | 152 V at IPPM = 2.0 A - Peak voltage seen by protected circuit during 10/1000 µs surge; critical for IC-level overvoltage margining. |
| PPPM (Peak Pulse Power) | 400 W - Surge energy handling capacity under standard 10/1000 µs waveform; supports repetitive transients at ≤0.01% duty cycle. |
| ID (Reverse Leakage) | 1.0 µA max at VWM - Minimal standby current leakage; preserves signal integrity and battery life in always-on circuits. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive or industrial environments. |
| Package | SMA (DO-214AC) - Surface-mount outline with 5.28 mm length, 4.50 mm width, and 2.29 mm height; compatible with standard SMT reflow profiles. |

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 | 600 W PPPM, SMB package (DO-214AA), higher thermal mass but larger footprint (4.6 × 3.9 mm vs. 5.3 × 4.5 mm). | Preferred where higher surge margin is needed and PCB space allows larger body size. | Select SMBJ110CA for >400 W surge headroom; verify pad layout compatibility with wider cathode band spacing. |
| 1.5KE110CA | 1500 W PPPM, axial DO-15 package, through-hole mounting, higher VBR tolerance (±5% vs. ±5.5%). | Suitable for prototyping, legacy designs, or high-energy industrial mains-side protection where SMT is not required. | Choose 1.5KE110CA only for non-SMT applications; not drop-in compatible due to mounting and thermal profile differences. |
Compared with P4SMA110CA-E3/61, SMBJ110CA offers greater surge robustness in a slightly larger SMT package, while 1.5KE110CA provides significantly higher power handling but requires through-hole assembly - making P4SMA110CA-E3/61 optimal for space-constrained, high-volume automated production of mid-power protection circuits.

FAQ
What is the clamping voltage of P4SMA110CA-E3/61 at its rated peak pulse current?
The P4SMA110CA-E3/61 has a maximum clamping voltage (VC) of 152 V at 2.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured with the device mounted on 5.0 mm × 5.0 mm copper pads and represents the upper limit of voltage imposed on the protected circuit during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P4SMA110CA-E3/61 suitable for automotive applications?
P4SMA110CA-E3/61 itself is a commercial-grade part (E3 suffix), but the P4SMA110CA-HE3 variant is AEC-Q101 qualified. For automotive use, specify the HE3 or HM3 suffix versions - they undergo additional stress testing including temperature cycling, HTRB, and ESD per AEC-Q101 Rev G. The P4SMA110CA-E3/61 may be used in non-safety-critical automotive subsystems only if validated per customer qualification protocols.
How does the bidirectional design of P4SMA110CA-E3/61 affect its PCB layout?
The P4SMA110CA-E3/61 has no polarity marking and identical electrical behavior in both directions, so PCB layout requires no orientation alignment - either terminal can connect to line or ground. This simplifies routing in differential or AC-coupled paths and eliminates risk of reverse installation. Layout must still follow Vishay's recommended 5.0 mm × 5.0 mm copper pad dimensions per terminal to ensure rated 400 W pulse power dissipation.
What is the maximum operating temperature for P4SMA110CA-E3/61?
The P4SMA110CA-E3/61 has a maximum junction temperature (TJ max) of +150 °C and an operating junction/storage temperature range of –65 °C to +150 °C. Derating begins above 25 °C ambient per Figure 2 in the datasheet, with thermal resistance RθJA = 120 °C/W. At 85 °C ambient, the device supports ~2.2 W steady-state power dissipation before reaching TJ max - sufficient for most transient-only applications with low duty cycle.
Does P4SMA110CA-E3/61 meet any safety certifications?
Yes, P4SMA110CA-E3/61 is Underwriters Laboratory (UL) recognized under file E136766 for protector classification per UL 497B, covering both unidirectional and bidirectional types. This certification validates its suitability for use in telecom, industrial, and consumer equipment requiring third-party safety approval for transient protection components - independent of end-product certification scope.
