Product details
Overview
P4SMA62CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in the P4SMA series, designed for clamping voltage transients on signal or power lines. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at 1 mA), 85 V maximum clamping voltage (VC) at 4.7 A peak pulse current, 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive applications.
For engineers reviewing the P4SMA62CAHE3_A/H datasheet, P4SMA62CAHE3_A/H pinout, P4SMA62CAHE3_A/H application, or P4SMA62CAHE3_A/H equivalent, this device is selected for robust ESD and surge protection in automotive sensor interfaces, industrial I/O lines, and telecom DC power rails where bidirectional clamping, low leakage (<1 µA at 53 V), and MSL Level 1 reflow compatibility are critical.
Technical Context
The P4SMA62CAHE3_A/H operates as a bidirectional avalanche diode with symmetrical clamping in both polarities, enabling transient suppression without polarity sensitivity. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, supporting fast response to sub-nanosecond ESD events.
Thermally, it exhibits RθJA = 120 °C/W and RθJL = 30 °C/W, with derating above 25 °C per Figure 2. It sustains 400 W peak pulse power only when mounted on 0.2" × 0.2" copper pads and is rated for continuous power dissipation of 3.3 W at 50 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1 mA - defines precise clamping onset threshold for bidirectional overvoltage events |
| VC @ IPPM | 85 V at 4.7 A - maximum voltage seen by protected circuit during 400 W transient (10/1000 µs) |
| VWM | 53.0 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| ID @ VWM | <1 µA - ultra-low leakage preserves signal integrity in high-impedance sensor or data lines |
| PPPM | 400 W (≤91 V), 300 W (>91 V) - peak surge handling capacity under standardized lightning/surge waveform |
| TJ max | +150 °C - enables operation in under-hood automotive environments and industrial enclosures |

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 VBR (60.8–67.2 V), same SMA package but SMB (DO-214AA) footprint - 2.5 mm wider body | Requires PCB pad revision; slightly higher clamping (90 V) reduces margin for 62 V nominal systems | Select when existing layout accommodates SMB and higher VC is acceptable for legacy designs |
| 1.5KE68CA | Through-hole TO-204AE (DO-201AE); 68 V VBR, 118 V VC at 5.3 A; 1500 W rating | Not SMT-compatible; used in high-energy legacy power supplies where board space allows axial leads | Choose only for through-hole prototyping or repair of older equipment - not drop-in for P4SMA62CAHE3_A/H |
Compared with SMBJ64CA and 1.5KE68CA, the P4SMA62CAHE3_A/H delivers optimal balance of compact SMA packaging, precise 62 V clamping, AEC-Q101 qualification, and 400 W surge capability - making it the preferred choice for new automotive and industrial SMT designs requiring bidirectional protection without layout compromise.

FAQ
What is the exact breakdown voltage range for P4SMA62CAHE3_A/H?
The P4SMA62CAHE3_A/H has a guaranteed breakdown voltage (VBR) range of 58.9 V to 65.1 V at 1 mA test current, measured per ANSI/IEEE C62.35. This ±5% tolerance ensures predictable clamping onset across production lots and temperature extremes, critical for protecting 48–60 V systems without premature conduction.
Is P4SMA62CAHE3_A/H unidirectional or bidirectional?
P4SMA62CAHE3_A/H is a bidirectional TVS diode, indicated by the "CA" suffix. It provides symmetrical clamping in both polarities - meaning it protects against positive and negative transients equally, with identical VBR, VC, and leakage characteristics in either direction. No polarity marking is present on the SMA package.
Does P4SMA62CAHE3_A/H meet automotive qualification standards?
Yes, P4SMA62CAHE3_A/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay documentation (Rev. 09-Jan-2024, Doc. #88367). It has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev. D, making it suitable for under-hood and cabin electronics.
What is the maximum clamping voltage of P4SMA62CAHE3_A/H under surge conditions?
The maximum clamping voltage (VC) of P4SMA62CAHE3_A/H is 85 V at 4.7 A peak pulse current (IPPM), tested with a 10/1000 µs waveform. This value represents the worst-case voltage imposed on the protected circuit during a 400 W transient event, ensuring downstream ICs rated for ≤100 V operation remain within safe limits.
Can P4SMA62CAHE3_A/H be used in high-humidity or harsh-environment applications?
Yes, P4SMA62CAHE3_A/H uses a molding compound rated UL 94 V-0 for flammability and is qualified to MSL Level 1 with peak reflow tolerance of 260 °C. Its glass-passivated junction and matte tin-plated leads provide resistance to moisture ingress and corrosion, supporting reliable operation in industrial enclosures and automotive under-hood environments per its -65 °C to +150 °C operating range.
