Product details
Overview
P4SMA200CAHE3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 200 V standoff voltage (VWM), 220 V breakdown voltage (VBR), and 400 W peak pulse power (10/1000 µs). It provides robust ESD and surge protection for signal lines in automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the P4SMA200CAHE3_A/I datasheet, P4SMA200CAHE3_A/I pinout, P4SMA200CAHE3_A/I application, or P4SMA200CAHE3_A/I equivalent, this AEC-Q101 qualified TVS offers verified clamping performance at 274 V under 1.1 A peak pulse current, low leakage (<1 µA at 171 V), and MSL Level 1 moisture sensitivity - critical for high-reliability automotive PCB assembly and long-term field operation.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns) to transient events such as inductive switching spikes or lightning-induced surges.
The device is rated for 150 °C maximum junction temperature and features low incremental surge resistance, enabling effective voltage clamping during repetitive 10/1000 µs transients at 0.01% duty cycle. Thermal resistance is 120 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 209–231 V at 1 mA - Confirmed minimum/maximum voltage at which device enters avalanche conduction; tight tolerance supports predictable protection threshold. |
| VC (Clamping Voltage) | 274 V at IPPM = 1.1 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case surge; enables downstream IC survival per IEC 61000-4-5 Level 3. |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy-handling capability for standardized 10/1000 µs waveform; sufficient for automotive load-dump and ISO 7637-2 pulse 1/2/5a. |
| ID (Reverse Leakage) | <1 µA at 171 V - Negligible standby current draw; avoids signal distortion or battery drain in always-on sensor nodes. |
| TJ max | 150 °C - Enables operation in under-hood automotive environments and industrial enclosures without derating below full power. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing; supports PPAP documentation. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. No polarity marking - bidirectional symmetry eliminates orientation concerns during automated placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Terminal A | One side of symmetrical PN junction; connects to line under protection (e.g., CAN_H or RS-485 A). |
| Cathode | Terminal K | Other side of symmetrical PN junction; connects to same line (bidirectional configuration requires no ground reference polarity). |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both directions - simplifies layout for AC-coupled or differential buses like CAN, RS-485, or audio lines. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling and HTRB - eliminates need for additional qualification testing in Tier-1 designs. |
| MSL Level 1 rating | Unlimited floor life at ≤30 °C/60% RH - supports just-in-time SMT assembly without baking or dry-pack requirements. |
| 400 W peak pulse power | Handles IEC 61000-4-5 2 kV open-circuit surge (10/700 µs equivalent) with margin - protects against indirect lightning and system-level ESD. |
| Glass passivated junction | Stable VBR over lifetime and temperature - prevents drift-induced false triggering or failure to clamp in harsh thermal environments. |
Applications

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 in larger SMB (DO-214AA) package; 600 W PPPM rating. | Higher power handling suits infrequent high-energy surges; less suitable for dense automotive PCBs due to 2.6 mm height. | Select when board space allows and surge duty cycle includes rare >400 W events. |
| 1.5KE200CA | Through-hole DO-15 package; identical 200 V VWM but higher 1.5 kW PPPM; higher junction capacitance (~100 pF). | Not suitable for high-speed data lines; intended for power rail or low-frequency analog protection. | Choose only for non-data applications where leaded mounting and higher surge margin are acceptable. |
Compared with SMBJ200CA and 1.5KE200CA, P4SMA200CAHE3_A/I delivers optimal balance of AEC-Q101 compliance, low-profile SMT fit, and precise 274 V clamping - making it the preferred choice for space-constrained, high-reliability signal-line protection where consistent timing and minimal parasitic capacitance matter.

FAQ
What is the clamping voltage of P4SMA200CAHE3_A/I at its rated peak pulse current?
The P4SMA200CAHE3_A/I has a maximum clamping voltage (VC) of 274 V when subjected to its specified peak pulse current (IPPM) of 1.1 A under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88367 and ensures protected circuits remain within safe voltage limits during transient events. The P4SMA200CAHE3_A/I maintains this clamping performance across its full operating temperature range.
Is P4SMA200CAHE3_A/I suitable for automotive applications?
Yes, P4SMA200CAHE3_A/I is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix "HE3". It undergoes stress testing for temperature cycling, high-temperature reverse bias, and ESD per AEC standards. The P4SMA200CAHE3_A/I is commonly deployed in engine control units, body electronics, and ADAS sensor modules where reliability under thermal and electrical stress is mandatory.
What does the "CA" suffix indicate in P4SMA200CAHE3_A/I?
The "CA" suffix in P4SMA200CAHE3_A/I denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VBR, VC, and leakage characteristics regardless of voltage polarity applied. This eliminates the need for polarity-aware layout and makes the P4SMA200CAHE3_A/I ideal for AC-coupled or differential signal lines such as CAN, RS-485, or audio paths.
What is the maximum operating temperature for P4SMA200CAHE3_A/I?
The P4SMA200CAHE3_A/I has a maximum junction temperature (TJ max) of +150 °C, validated per Vishay's thermal characterization. This allows uninterrupted operation in under-hood automotive environments and sealed industrial enclosures. Derating begins above TA = 25 °C per Figure 2 in document 88367, with 100% power capability maintained up to +70 °C ambient on standard PCB pad layout.
Does P4SMA200CAHE3_A/I require special handling during PCB assembly?
No - P4SMA200CAHE3_A/I meets MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30 °C/60% RH and withstands peak reflow temperatures up to 260 °C without preconditioning. The P4SMA200CAHE3_A/I is compatible with standard lead-free reflow profiles and requires no baking, dry packing, or humidity-controlled storage prior to SMT placement.
