Product details
Overview
P4SMA200CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMA (DO-214AC) package, designed for clamping voltage transients on signal or power lines. It features 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), 274 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect MOSFETs, sensor interfaces, and telecom line drivers against ESD and inductive switching surges.
For engineers reviewing the P4SMA200CAHE3_A/H datasheet, P4SMA200CAHE3_A/H pinout, P4SMA200CAHE3_A/H application, or P4SMA200CAHE3_A/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, clamping performance at rated surge current, thermal resistance data, and direct alternative part comparisons for automotive and industrial transient protection design.
Technical Context
The P4SMA200CAHE3_A/H operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients without polarity dependence. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 µA at VWM), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
It delivers 274 A peak pulse current under standardized 10/1000 µs waveform conditions when mounted on 5.0 mm × 5.0 mm copper pads, with clamping voltage limited to 328 V at IPPM - enabling robust protection of 200 V-rated circuits without overstressing downstream components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff Voltage) | 200 V - maximum continuous reverse operating voltage before conduction begins; defines circuit's normal operating margin before clamping activates. |
| VBR (Breakdown Voltage) | 220 V min - voltage at which device enters avalanche conduction at 1 mA test current; ensures reliable triggering above system operating voltage. |
| VC (Clamping Voltage) | 328 V at 274 A - maximum voltage seen across protected line during full-rated transient; determines stress on downstream ICs or MOSFETs. |
| PPPM (Peak Pulse Power) | 400 W - energy-handling capability under 10/1000 µs waveform; sufficient for IEC 61000-4-5 Level 3 surge events in industrial interfaces. |
| RθJA | 120 °C/W - junction-to-ambient thermal resistance; requires adequate PCB copper area (0.2" × 0.2") to maintain TJ ≤ 150 °C under repetitive surges. |
| AEC-Q101 Qualified | Yes - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard; suitable for ADAS sensor power rails. |
| Package | SMA (DO-214AC) - surface-mount package with 2.54 mm lead pitch; compatible with automated placement and reflow soldering per J-STD-020. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with matte tin-plated leads, UL 94 V-0 rated. Bidirectional construction has no polarity marking; terminals are symmetrical anode/cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Provides low-impedance path for negative-going transients; electrically identical to cathode in CA devices. |
| Cathode | Transient return path (bidirectional) | Provides low-impedance path for positive-going transients; functionally interchangeable with anode in CA configuration. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables single-device protection against IEC 61000-4-5 surges up to 1 kV open-circuit in 2 Ω source impedance systems. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ESD > 10 kV/µs), improving protection fidelity. |
| MSL Level 1, 260 °C peak reflow | Supports standard lead-free assembly without preconditioning or special handling; eliminates moisture-related popcorning risk. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive under-hood and infotainment applications requiring extended temperature operation (-65 °C to +150 °C). |
| Glass passivated junction | Ensures long-term stability of VBR and leakage current over 10+ years in humid or high-bias environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Same VWM/VBR/VC specs but SMB package (DO-214AA); higher RθJA (110 °C/W) due to larger pad area requirement. | Better suited for higher-power layouts where 600 W PPPM headroom is needed; less space-constrained than SMA. | Select SMBJ200CA when board real estate allows larger footprint and thermal management uses ≥1 cm² copper per terminal. |
| 1.5KE200CA | Through-hole DO-201 package; 1500 W PPPM rating but slower response (>1 ns vs. <1 ns for P4SMA); higher junction capacitance (~100 pF). | Used in legacy power supply inputs or AC mains protection where layout density is not critical and speed is secondary. | Choose 1.5KE200CA only for non-high-speed applications where PCB space permits through-hole mounting and sub-100 MHz bandwidth is acceptable. |
Compared with SMBJ200CA and 1.5KE200CA, the P4SMA200CAHE3_A/H offers optimal balance of miniaturization, AEC-Q101 compliance, and sub-nanosecond response - making it preferred for modern automotive sensor modules and compact industrial communications hardware where surface-mount density and automotive qualification are mandatory.

FAQ
What does the "CA" suffix indicate in P4SMA200CAHE3_A/H?
The "CA" suffix denotes a bidirectional Transient Voltage Suppressor. Unlike unidirectional variants (e.g., P4SMA200A), the P4SMA200CAHE3_A/H conducts symmetrically in both polarities - essential for protecting AC-coupled lines, differential buses like RS-485, or any circuit where voltage transients may swing positive or negative relative to ground. This eliminates the need for polarity-aware placement during assembly.
Is P4SMA200CAHE3_A/H suitable for automotive applications?
Yes, the P4SMA200CAHE3_A/H is AEC-Q101 qualified (confirmed by HE3 suffix and Vishay documentation), tested for temperature cycling, high-temperature reverse bias, and ESD per automotive standards. It operates from −65 °C to +150 °C and is rated for under-hood and ADAS sensor power rail protection where transient immunity and long-term reliability are critical.
What is the clamping voltage of P4SMA200CAHE3_A/H at its rated peak pulse current?
The P4SMA200CAHE3_A/H clamps to a maximum of 328 V at its rated peak pulse current of 274 A (10/1000 µs waveform). This value is measured under standardized test conditions with 0.2" × 0.2" copper pads per terminal and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
How does the SMA package of P4SMA200CAHE3_A/H compare to SMB or SMC in terms of power handling?
The SMA (DO-214AC) package of P4SMA200CAHE3_A/H supports 400 W peak pulse power with proper PCB layout (5.0 mm × 5.0 mm copper pads), whereas SMB (DO-214AA) and SMC (DO-214AB) offer higher thermal mass and thus greater sustained power capability. However, the P4SMA200CAHE3_A/H achieves best-in-class power density for its footprint - delivering 400 W in the smallest standardized surface-mount TVS outline.
Does P4SMA200CAHE3_A/H require derating at elevated ambient temperatures?
Yes, the P4SMA200CAHE3_A/H must be derated above TA = 25 °C per Figure 2 in the Vishay datasheet (Document 88367). At 85 °C ambient, its peak pulse power drops to approximately 280 W - meaning designers must verify that expected surge energy remains within the derated PPPM envelope, especially in enclosed or thermally constrained enclosures.
