Product details
Overview
P4SMA62AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping transient overvoltages on power and signal lines. It features 62 V breakdown voltage (VBR = 58.9–65.1 V at IT = 1.0 mA), 53.0 V maximum stand-off voltage (VWM), and 85.0 V clamping voltage (VC) at 4.7 A peak pulse current (IPPM), with 400 W peak pulse power rating (10/1000 µs waveform). It is AEC-Q101 qualified and used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial electronics.
For engineers reviewing the P4SMA62AHE3_A/H datasheet, P4SMA62AHE3_A/H pinout, P4SMA62AHE3_A/H application, or P4SMA62AHE3_A/H equivalent, key selection criteria include unidirectional polarity, 53.0 V working voltage, 85.0 V clamping performance under 4.7 A surge, AEC-Q101 qualification status, and SMA package compatibility with automated SMT assembly.
Technical Context
This TVS diode operates as a voltage-clamping protection device that remains high-impedance below VWM (53.0 V) and rapidly transitions to low-impedance conduction above VBR (min. 58.9 V) to divert transient energy. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
It is rated for 400 W peak pulse power (10/1000 µs), derated to 300 W above 91 V, and supports repetitive surges at 0.01% duty cycle. Thermal resistance is 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead), with operating junction temperature range of –65 °C to +150 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A-E3/52 (Vishay) | Higher VWM (55.1 V), same VC (103 V), larger SMB package (DO-214AA), 600 W PPPM | Requires PCB layout change; better suited for higher-energy surges where space allows | Select when higher surge margin is needed and board area permits larger footprint |
| 1.5SMC62A (ON Semiconductor) | Identical VWM (53.0 V), VC (85.0 V), and PPPM (400 W); same SMA package; RoHS-compliant but not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not required |
Compared with P4SMA62AHE3_A/H, SMBJ64A-E3/52 offers higher surge capacity but requires layout revision, while 1.5SMC62A matches electrical specs and form factor but omits AEC-Q101 validation-making P4SMA62AHE3_A/H the sole option for production automotive applications needing both performance and qualification.

FAQ
What is the clamping voltage of P4SMA62AHE3_A/H at its rated peak pulse current?
The P4SMA62AHE3_A/H has a maximum clamping voltage (VC) of 85.0 V at its rated peak pulse current (IPPM) of 4.7 A, measured using the standard 10/1000 µs double-exponential waveform. This value ensures predictable overvoltage limiting for downstream components and is verified per the Vishay P4SMA datasheet revision 09-Jan-2024. The P4SMA62AHE3_A/H maintains this clamping performance across its full operating temperature range.
Is P4SMA62AHE3_A/H suitable for automotive applications?
Yes, P4SMA62AHE3_A/H is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its construction-glass-passivated junction, MSL Level 1 rating, and –65 °C to +150 °C junction temperature range-meets automotive environmental and reliability requirements. The "HE3" suffix explicitly denotes AEC-Q101 qualification per Vishay's ordering nomenclature.
What does the "_A/H" suffix mean in P4SMA62AHE3_A/H?
In P4SMA62AHE3_A/H, "_A" indicates the revision level (Revision A) per Vishay's internal documentation, and "/H" specifies the packaging format: 7-inch diameter plastic tape and reel, with 1800 units per reel. This ordering code also confirms RoHS compliance and AEC-Q101 qualification. The base "HE3" denotes AEC-Q101 qualified, RoHS-compliant version in SMA package.
How does P4SMA62AHE3_A/H differ from bidirectional variants like P4SMA62CA?
P4SMA62AHE3_A/H is unidirectional, with polarity marked by a cathode band and intended for DC line protection where reverse conduction must be blocked. In contrast, P4SMA62CA is bidirectional, symmetric in both directions, and lacks polarity marking-suitable for AC or differential signal lines. Their VBR, VWM, and VC values differ accordingly: P4SMA62CA has lower VWM (48.0 V) and higher VC (95.0 V), making P4SMA62AHE3_A/H preferable for 53 V DC rail protection.
What is the thermal resistance of P4SMA62AHE3_A/H, and how does it affect layout design?
P4SMA62AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and junction-to-lead resistance (RθJL) of 30 °C/W. These values assume mounting on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures under repetitive surges, PCB layout must provide adequate copper area and avoid thermal bottlenecks-especially critical in automotive under-hood applications where ambient temperatures exceed 85 °C.
