Product details
Overview
P4SMA62CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on signal or power lines. It features a 53.0 V standoff voltage (VWM), 65.1 V maximum breakdown voltage (VBR), 85.0 V clamping voltage (VC) at 4.7 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and communication lines in automotive and industrial control systems.
For engineers reviewing the P4SMA62CAHM3/I datasheet, P4SMA62CAHM3/I pinout, P4SMA62CAHM3/I application, or P4SMA62CAHM3/I equivalent, this device delivers AEC-Q101 qualified transient suppression for bidirectional signal paths where low clamping ratio, fast response (<1 ns), and halogen-free RoHS compliance are required in space-constrained layouts.
Technical Context
The P4SMA62CAHM3/I operates as a bidirectional avalanche diode, symmetrically clamping voltage surges above ±65.1 V in either polarity without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
Thermal performance is defined by 120 °C/W junction-to-ambient resistance (RθJA) on standard 0.2" × 0.2" copper pads, enabling reliable operation up to +150 °C junction temperature. The 3.3 W steady-state power dissipation (PD) and 40 A surge capability (IFSM, unidirectional only) confirm its suitability for repetitive transient events in automotive ECUs and industrial I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1.0 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 85.0 V at 4.7 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability under standardized 10/1000 μs waveform; validates robustness against lightning-induced surges. |
| ID (Reverse Leakage) | <1.0 μA at VWM - Minimal standby current; preserves signal integrity and battery life in always-on sensor nodes. |

IC Role / Device Role: Symmetric TVS pair (one per line) or single bidirectional device across bus differential pair. Use Value: Clamps common-mode surges to <85 V without disrupting 1–5 Mbps CAN signaling integrity or introducing capacitive loading >100 pF. |
| Consumer USB Port ESD Protection | Telecom DSL Line Surge Suppression |
Use Scenario: Shielding USB 2.0 D+/D− lines in set-top boxes and smart home hubs from human-body-model (HBM) ESD events. IC Role / Device Role: Low-capacitance bidirectional TVS placed directly at connector entry point. Use Value: Sub-100 pF junction capacitance (per datasheet Fig. 4 at VWM) avoids signal rise-time degradation while passing ±15 kV contact discharge per IEC 61000-4-2. |
Use Scenario: Front-end protection of ADSL/VDSL line interface circuits exposed to lightning-induced surges on outdoor copper pairs. IC Role / Device Role: Primary surge limiter mounted before transformer coupling and line driver ICs. Use Value: Absorbs 400 W transient energy per ITU-T K.20/K.21 standards while maintaining <1.0 μA leakage to preserve line impedance matching and SNR. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Higher VWM (58.1 V), same VC (85.0 V), larger SMB package (DO-214AA); 600 W PPPM rating. | Requires larger PCB area; better suited for higher-energy surges but less space-efficient than SMA. | Select when higher surge margin is needed and board space permits larger footprint. |
| 1.5KE68CA | Through-hole DO-15 package; 68 V VBR, 118 V VC at 3.4 A; 1500 W PPPM but slower thermal response. | Not surface-mountable; incompatible with automated assembly; unsuitable for high-density or automotive vibration environments. | Consider only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SMBJ64CA and 1.5KE68CA, the P4SMA62CAHM3/I offers optimal balance of compact SMA packaging, AEC-Q101 qualification, and precise 53.0 V standoff - making it preferred for new automotive and industrial SMT designs requiring verified reliability and layout efficiency.

FAQ
What does the "CA" suffix indicate in P4SMA62CAHM3/I?
The "CA" suffix denotes a bidirectional configuration: the P4SMA62CAHM3/I functions identically in both polarities, clamping positive and negative transients symmetrically. This eliminates the need for polarity-aware layout and simplifies protection of AC-coupled or differential signal paths - a key advantage over unidirectional variants like P4SMA62AHM3/I.
Is P4SMA62CAHM3/I suitable for automotive applications?
Yes, P4SMA62CAHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction validated for automotive environments. Its 150 °C max junction temperature, MSL Level 1 rating, and tested performance under ISO 7637-2 pulse waveforms make it appropriate for engine control units, body electronics, and ADAS sensor interfaces.
What is the clamping voltage of P4SMA62CAHM3/I and why does it matter?
The P4SMA62CAHM3/I has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (IPPM) under 10/1000 μs waveform. This value defines the highest voltage imposed on protected circuitry during a surge - critical for ensuring downstream ICs (e.g., CAN transceivers rated to 70 V absolute max) remain within safe operating limits.
How does the SMA (DO-214AC) package of P4SMA62CAHM3/I compare to SMB or SMC packages?
The SMA package of P4SMA62CAHM3/I measures 5.28 mm × 4.50 mm - smaller than SMB (DO-214AA) and significantly smaller than SMC (DO-214AB). This enables higher board density in space-constrained applications like automotive camera modules or portable telecom equipment, while retaining sufficient thermal mass for 400 W pulse handling when mounted on recommended 0.2" × 0.2" copper pads.
Does P4SMA62CAHM3/I require a heatsink for normal operation?
No external heatsink is required for P4SMA62CAHM3/I under typical transient conditions. Its RθJA of 120 °C/W is specified with standard 0.2" × 0.2" copper pads per terminal - sufficient for intermittent surge events. Continuous power dissipation is limited to 3.3 W (PD), so sustained DC stress must remain well below this level; thermal design should verify junction temperature stays ≤150 °C under worst-case ambient and power conditions.
