Product details
Overview
P4SMA200AHE3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 200 V standoff voltage (VWM), 210 V minimum breakdown voltage (VBR), and 274 V maximum clamping voltage (VC) at 1.1 A peak pulse current (IPPM), designed to protect power rails and signal lines in automotive and industrial electronics against ESD and lightning-induced transients.
For engineers reviewing the P4SMA200AHE3/61 datasheet, P4SMA200AHE3/61 pinout, P4SMA200AHE3/61 application, or P4SMA200AHE3/61 equivalent, this AEC-Q101 qualified TVS offers verified 400 W peak pulse power (10/1000 μs), low thermal resistance (RθJL = 30 °C/W), and RoHS-compliant matte tin-plated leads suitable for automated SMT assembly and high-reliability automotive subsystems.
Technical Context
The P4SMA200AHE3/61 operates as a unidirectional avalanche-clamping device with glass-passivated junction, enabling sub-nanosecond response to transient overvoltages. Its 200 V VWM ensures compatibility with 170–200 V DC bus systems, while the 274 V VC at IPPM guarantees safe voltage limiting during 400 W surge events.
Thermally, it features RθJA = 120 °C/W (free-air) and RθJL = 30 °C/W, supporting stable operation up to TJ = 150 °C. The device meets J-STD-020 MSL Level 1 and is qualified per AEC-Q101 for automotive under-hood and powertrain applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 200 V - Maximum continuous reverse working voltage before clamping begins; defines operating margin for 170–200 V DC systems. |
| VBR (Breakdown Voltage) | 190–210 V at IT = 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on within ±5 % of nominal rating. |
| VC (Clamping Voltage) | 274 V at IPPM = 1.1 A (10/1000 μs) - Peak voltage seen by protected circuit during full-rated surge; enables IEC 61000-4-5 Level 4 compliance. |
| PPPM (Peak Pulse Power) | 400 W - Sustains 10/1000 μs transients without degradation; derates to 300 W above 91 V per spec, confirmed at TA = 25 °C on 5.0 mm × 5.0 mm copper pads. |
| ID (Reverse Leakage) | 1.0 μA max at VWM = 200 V - Negligible standby current; avoids power loss in high-impedance sensing or battery-backed circuits. |
| TJ max | 150 °C - Enables use in under-hood automotive environments and industrial power supplies with elevated ambient temperatures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing; ordering code HE3 denotes qualification. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads; polarity indicated by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to lower-potential side of protected line; enables unidirectional clamping from cathode to anode. |
| Cathode | Current exit terminal during reverse-biased clamping | Connected to higher-potential rail (e.g., VBUS); conducts avalanche current when transient exceeds VWM. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 surges up to 4 kV in 2 Ω/12 Ω coupling networks without derating. |
| Glass passivated chip junction | Ensures long-term stability of VBR and leakage under thermal cycling and humidity stress, critical for automotive life-cycle validation. |
| MSL Level 1 (260 °C peak reflow) | Supports single-pass lead-free reflow soldering without moisture-related popcorning or delamination. |
| AEC-Q101 qualification (HE3 suffix) | Validates suitability for automotive powertrain, body control, and ADAS modules requiring zero-failure field performance. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), improving protection margin for sensitive gate drivers and ADC inputs. |
Applications
| Automotive Power Supply Protection | Industrial Motor Drive DC Bus Clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A-E3/5A | Same VWM/VBR/VC specs, but rated for 400 W only up to 170 V; derates to 300 W at 200 V; no AEC-Q101 qualification. | Limited to commercial/industrial use; not approved for automotive production programs. | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification assurance. |
| 1.5SMC200AHE3_A | Higher package thermal mass (SMC vs SMA); same electrical specs but RθJA = 40 °C/W; 1500 W peak power rating. | Better suited for high-duty-cycle or repeated surge environments where heat dissipation is critical. | Choose when board space allows larger SMC package and system requires >400 W single-pulse headroom. |

FAQ
What is the clamping voltage of P4SMA200AHE3/61 at its rated peak pulse current?
The P4SMA200AHE3/61 has a maximum clamping voltage (VC) of 274 V at 1.1 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet (Doc. #88367) and defines the upper voltage limit imposed on protected circuits during full-rated surge events. The P4SMA200AHE3/61 maintains this clamping performance across its qualified temperature range and after AEC-Q101 stress testing.
Is P4SMA200AHE3/61 suitable for automotive applications?
Yes, P4SMA200AHE3/61 is explicitly AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number. It has passed automotive-grade reliability tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per JESD22-A114. The P4SMA200AHE3/61 is approved for use in engine control units, body electronics, and ADAS modules where transient immunity and long-term stability are mandatory.
What is the standoff voltage rating of P4SMA200AHE3/61, and how does it relate to system design?
The P4SMA200AHE3/61 has a standoff voltage (VWM) of 200 V, meaning it remains non-conductive up to this DC or RMS voltage level. This rating allows direct placement on 170–200 V DC bus lines-such as those found in 48 V mild-hybrid automotive systems or industrial servo drives-without leakage or thermal runaway. The P4SMA200AHE3/61's 200 V VWM provides a 10 % margin below its 210 V minimum breakdown voltage, ensuring reliable operation under normal conditions.
Does P4SMA200AHE3/61 have a bidirectional variant?
No, P4SMA200AHE3/61 is a unidirectional TVS diode, as confirmed by its "A" suffix and cathode band marking. Bidirectional variants in the P4SMA series use the "CA" suffix (e.g., P4SMA200CA). The P4SMA200AHE3/61 is intended for DC rail protection where polarity is fixed; using it in AC or floating applications would require external circuitry or selection of a CA-part.
What is the thermal resistance from junction to lead (RθJL) for P4SMA200AHE3/61, and why does it matter?
The P4SMA200AHE3/61 has a typical junction-to-lead thermal resistance (RθJL) of 30 °C/W, per Vishay's thermal characteristics table. This low value enables efficient heat transfer from the silicon die to the PCB copper via the leads, supporting sustained operation at elevated ambient temperatures. For the P4SMA200AHE3/61, this directly improves reliability in enclosed automotive enclosures where airflow is limited and junction temperature must stay below 150 °C.
