Product details
Overview
P4SMA200CAHE3/5A from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMA (DO-214AC) package, rated for 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), and 400 W peak pulse power (10/1000 µs). It provides clamping protection for automotive-grade sensor signal lines, power rails, and I/O interfaces against ESD and inductive switching transients.
For engineers reviewing the P4SMA200CAHE3/5A datasheet, P4SMA200CAHE3/5A pinout, P4SMA200CAHE3/5A application, or P4SMA200CAHE3/5A equivalent, this AEC-Q101 qualified TVS offers verified bidirectional clamping, low leakage (<1 µA at VWM), and MSL Level 1 moisture sensitivity - critical for high-reliability automotive and industrial PCB designs requiring robust transient immunity without polarity constraints.
Technical Context
This device operates as a voltage-clamped shunt protector: when reverse (or either direction for bidirectional mode) voltage exceeds VBR (220–242 V), it avalanches to limit transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Designed for unclamped transient suppression, it delivers 274 V maximum clamping voltage (VC) at 1.1 A IPPM, with thermal resistance RθJA = 120 °C/W and operating junction temperature up to +150 °C - enabling reliable operation on standard 5.0 mm × 5.0 mm copper pads without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 200 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin for 24 V or 48 V DC systems. |
| VBR (Breakdown) | 220–242 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients above system nominal voltage. |
| VC (Clamping) | 274 V at IPPM = 1.1 A - Measured peak voltage across device during 10/1000 µs surge; determines maximum stress imposed on protected ICs. |
| PPPM | 400 W - Peak pulse power handling per 10/1000 µs waveform; supports repeated surge events at ≤0.01% duty cycle. |
| ID (Leakage) | <1 µA at 200 V - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max | +150 °C - Maximum junction temperature rating; enables deployment in under-hood automotive environments and industrial enclosures. |
| AEC-Q101 | Qualified - Validated for automotive electronics per stress test requirements including HTOL, TC, and ESD; supports PPAP documentation. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads; meets UL 94 V-0 flammability and J-STD-002 solderability standards. MSL Level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; common reference for bidirectional clamping | No marking on device; symmetric terminals enable polarity-agnostic placement on PCB - simplifies layout and eliminates orientation errors. |

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 ratings but SMB (DO-214AA) package - 2.5 mm wider body, higher RθJA (100 °C/W), lower IPPM (1.2 A) | Requires larger PCB footprint; less suitable for dense automotive modules where SMA's 4.93 mm length is critical | Select when board space allows larger package and higher thermal mass is preferred for intermittent surge duty. |
| 1.5SMC200CA | Same electrical specs but SMC (DO-214AB) package - 7.1 mm length, 2.5 mm height, RθJA = 75 °C/W, IPPM = 1.3 A | Higher power derating capability above 70 °C ambient; not AEC-Q101 qualified - limits automotive use | Prefer for industrial power supplies needing extended thermal headroom but lacking automotive qualification requirements. |
Compared with SMBJ200CA and 1.5SMC200CA, the P4SMA200CAHE3/5A uniquely combines AEC-Q101 qualification, SMA footprint efficiency, and MSL Level 1 compatibility - making it the optimal choice for space-constrained, high-reliability automotive PCBs where reflow simplicity and qualification traceability are mandatory.

FAQ
What does the "CA" suffix indicate in P4SMA200CAHE3/5A?
The "CA" suffix in P4SMA200CAHE3/5A denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VBR, VC, and IPPM characteristics regardless of voltage polarity applied across its terminals. This eliminates the need for polarity-aware layout and supports AC-coupled or floating signal line protection.
Is P4SMA200CAHE3/5A suitable for automotive applications?
Yes, P4SMA200CAHE3/5A is AEC-Q101 qualified and carries the "HE3" automotive suffix, confirming compliance with stress tests including high-temperature operating life, temperature cycling, and ESD. It is approved for use in engine control, ADAS sensor interfaces, and body electronics where sustained +150 °C junction temperature and robust surge immunity are required.
What is the maximum clamping voltage (VC) of P4SMA200CAHE3/5A and at what current is it specified?
The maximum clamping voltage (VC) of P4SMA200CAHE3/5A is 274 V, measured at a peak pulse current (IPPM) of 1.1 A using the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the SMA (DO-214AC) package of P4SMA200CAHE3/5A compare to SMB or SMC alternatives in terms of thermal performance?
The SMA package of P4SMA200CAHE3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W, higher than SMB (100 °C/W) or SMC (75 °C/W) variants - meaning it requires more careful thermal pad design. However, its compact 4.93 mm × 2.92 mm footprint enables denser layouts, and its MSL Level 1 rating supports direct reflow without baking, offsetting thermal trade-offs in space-constrained automotive modules.
What is the reverse leakage current (ID) specification for P4SMA200CAHE3/5A at its rated standoff voltage?
P4SMA200CAHE3/5A exhibits a maximum reverse leakage current (ID) of 1 µA at its rated standoff voltage (VWM) of 200 V, tested at TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes quiescent power loss in battery-powered systems - a key advantage over older TVS families with ID >5 µA at rated VWM.
