Product details
Overview
P4SMA8.2CAHE3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in the P4SMA series, designed for clamping voltage transients on signal and power lines. It features a 8.2 V breakdown voltage (VBR = 7.79–8.61 V at 10 mA), 5.8 V standoff voltage (VWM), 12.1 V maximum clamping voltage (VC) at 33.1 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial systems.
For engineers reviewing the P4SMA8.2CAHE3/61 datasheet, P4SMA8.2CAHE3/61 pinout, P4SMA8.2CAHE3/61 application, or P4SMA8.2CAHE3/61 equivalent, this AEC-Q101-qualified, RoHS-compliant bidirectional TVS offers verified clamping performance, low incremental surge resistance, and MSL Level 1 reflow compatibility up to 260 °C - critical for automotive-grade ESD and load-dump protection design validation.
Technical Context
The P4SMA8.2CAHE3/61 operates as a bidirectional avalanche diode, symmetrically clamping transient voltages in both polarities without polarity marking. Its glass-passivated junction enables fast response time (<1 ns) and stable breakdown characteristics across -65 °C to +150 °C operating range.
It delivers 400 W peak pulse power (10/1000 µs) with 12.1 V clamping at 33.1 A, and exhibits 0.065 %/°C temperature coefficient of VBR. Designed for mounting on 5.0 mm × 5.0 mm copper pads, it achieves thermal resistance RθJA = 120 °C/W and RθJL = 30 °C/W.

Use Scenario: Protecting RS-485 transceiver pins in building automation gateways connected to long outdoor cabling. IC Role / Device Role / Timing Role: Front-end transient suppressor limiting line-to-ground surges to safe levels before differential receiver inputs. Use Value: 400 W rating handles induced lightning surges; AEC-Q101 qualification ensures longevity in uncontrolled environmental deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0CA | Higher VWM = 6.4 V, lower VC = 12.0 V at 33.3 A, same 400 W rating but SMB package (DO-214AA) | Larger footprint; better suited for higher-current PCB layouts with >10 mm² copper area | Select when board space allows larger package and tighter clamping tolerance is prioritized |
| 1.5KE8.2CA | Through-hole TO-218 package, same VBR/VC, 1500 W rating but slower response due to higher junction capacitance | Not suitable for high-speed signal lines; intended for bulk power rail protection only | Choose only for legacy through-hole designs where rework to SMT is not feasible |
Compared with SMBJ8.0CA and 1.5KE8.2CA, the P4SMA8.2CAHE3/61 provides optimal balance of compact SMA footprint, AEC-Q101 qualification, and precise 5.8 V standoff-making it the preferred choice for new automotive and space-constrained industrial designs requiring certified reliability.

FAQ
What is the clamping voltage of P4SMA8.2CAHE3/61 under standard 10/1000 µs surge conditions?
The P4SMA8.2CAHE3/61 has a maximum clamping voltage (VC) of 12.1 V at 33.1 A peak pulse current with a 10/1000 µs waveform. This value is measured per JEDEC standards and reflects the actual voltage imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings. The P4SMA8.2CAHE3/61 maintains this performance across its full operating temperature range.
Is P4SMA8.2CAHE3/61 suitable for automotive applications?
Yes, P4SMA8.2CAHE3/61 is AEC-Q101 qualified and carries the HE3 suffix denoting RoHS-compliant, automotive-grade construction. It undergoes rigorous testing for temperature cycling, highly accelerated life testing (HALT), and ESD immunity - making it approved for use in engine control units, ADAS sensor modules, and body electronics where reliability under thermal stress and vibration is mandatory. The P4SMA8.2CAHE3/61 meets all requirements for under-hood deployment.
What does the "CA" suffix indicate in P4SMA8.2CAHE3/61?
The "CA" suffix in P4SMA8.2CAHE3/61 specifies a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VBR, VC, and IPPM characteristics regardless of voltage polarity. Unlike unidirectional variants (e.g., P4SMA8.2A), the P4SMA8.2CAHE3/61 has no cathode band marking and is used where AC-coupled or polarity-agnostic protection is required, such as on differential signal lines or AC power inputs.
What is the standoff voltage (VWM) of P4SMA8.2CAHE3/61, and why does it matter?
The standoff voltage (VWM) of P4SMA8.2CAHE3/61 is 5.8 V - the maximum continuous reverse voltage the device can block without exceeding 200 µA leakage current. This parameter ensures the P4SMA8.2CAHE3/61 remains non-conductive during normal operation, avoiding power loss or false triggering, while still responding instantly to transients exceeding VWM. It is selected to sit safely below system operating voltage but above noise margins.
Does P4SMA8.2CAHE3/61 require special PCB layout considerations?
Yes - for optimal surge handling, P4SMA8.2CAHE3/61 must be mounted on minimum 5.0 mm × 5.0 mm copper pads per terminal as specified in the Vishay datasheet. Smaller pads reduce thermal dissipation and increase clamping voltage under repeated surges. Additionally, short, direct traces to protected nodes minimize inductance, preserving sub-nanosecond response. The P4SMA8.2CAHE3/61's SMA package supports standard reflow profiles with peak temperature up to 260 °C (MSL Level 1).
